00:00:00【The Legend of Zelda Ocarina of Time】
00:00:22石瓢を纏い切れ落ちる岩の峰々
00:00:26カナダ・ロッキー山脈です
00:00:36氷河に削られた大地には息を飲む絶景や自然現象が
00:00:44何だこれ!
00:00:46Have you ever seen anything like that?
00:00:50現れたのは七色に輝く奇妙な湖
00:00:59まさに見たことのない奇観
00:01:09絶景の宝庫カナダ南西部
00:01:13夏と冬ではその姿はがらりと変わります
00:01:20夏と冬の気温差は最大80度以上
00:01:26この差が類稀な絶景を生み出すというのです
00:01:33冬、全面凍結した湖
00:01:38氷の中には天然のアートが
00:01:44北緯58度、極北の大雪原
00:01:49夏、姿を現したのは広大な砂漠でした
00:01:57サラッサラ、ほんと砂漠の砂ですね
00:02:02アルファバスカの砂はグレイシャーで作られています
00:02:07浮かび上がってきたのはカンとダンの壮絶な攻め合い
00:02:15マイナス20度の滝壺に現れたのは巨大な氷の塔
00:02:24熱間積雪量12メートルの豪雪地帯で目の当たりにしたのは
00:02:32巨大な流れ
00:02:37カナダ南西部絶景地帯
00:02:43カンとダンが生み出す神秘の世界を体感します
00:03:02東京オリンピック
00:03:06今回皆さんをお連れするのはカナダ南西部、ロッキー山脈周辺
00:03:14ここではカンとダンの攻め合いが生み出す驚きの造形や自然現象に出会えるんです
00:03:22まずはカルナリーへ
00:03:25かつて東京オリンピックが開催された町
00:03:31東京オリンピック
00:03:35着きましたね
00:03:37結構涼しいですね
00:03:39日本よりカラッとして風が結構気持ちいいですね
00:03:46訪れたのは7月の初め
00:03:49湿度は45%
00:03:52日本の夏と比べると快適なんでしょうね
00:04:01人口は160万ほど
00:04:04一方年間300万人の観光客が訪れます
00:04:14地元の人におすすめの絶景ポイントを聞いてみました
00:04:20カナダのロッキー山脈
00:04:22世界で一番美しい場所を見ることができる
00:04:26どこでも楽しんでください
00:04:29Many beautiful viewpoints, hikes, wildlife, rivers, streams
00:04:37It's really beautiful
00:04:43カルナリーの西
00:04:45およそ80キロにそびえるカナディアンロッキー
00:04:49地元の人たちが絶景の宝庫と太鼓板を押す場所へ
00:04:59いざ
00:05:05カナダ南西部を縦に貫くカナディアンロッキー
00:05:10南北400キロにわたって3000メートル級の山々が連なります
00:05:18実に壮大
00:05:33車を走らせること1時間半
00:05:39山脈にある観光の拠点バンフに着きました
00:05:47バンフ
00:05:53綺麗なところですね
00:05:56山に囲まれて観光客もいっぱいいますね
00:06:10まずはヘリコプターに乗り込み
00:06:13空の上からカナディアンロッキーの雄大な風景を体感してみましょう
00:06:34雪と岩が入り組んだ険しい山々
00:06:39標高3000メートルを超える峰を要するカナディアンロッキー
00:06:47真夏でも雪がなくなることはないようです
00:06:57旧春な山々の間には深い谷
00:07:08雪どけ水はこうした谷を流れ周囲に不思議な色を放つ湖を形成
00:07:17これがこの山脈の特徴なんです
00:07:29そしてもう一つの特徴が氷が
00:07:34その数はなんと3000に及ぶんです
00:07:46その一つアレクサンドラ氷河
00:07:51乱立する氷の塔
00:07:56この不思議な造形は氷の下の斜面が階段状になっているため
00:08:02氷河が動くと無数の亀裂が入り形作られるのだといいます
00:08:17かつて骨幹の時代を経験したカナディアンロッキー
00:08:24その成り立ちについて探っていくことにしましょう
00:08:33カナディアンロッキー
00:08:41案内人はカナディアンロッキーガイド歴15年のJP14さんです
00:08:48Pretty excited for the next few days and go see all the lakes and mountains and glaciers
00:08:53and everything else we have here for you
00:09:01まずはカナディアンロッキーの成り立ちがよくわかるという展望台へ
00:09:11ゴンドラで一気に標高2000メートルの地点に向かいます
00:09:18Hi!
00:09:28But you think the view is pretty amazing
00:09:39Yeah and the one that's probably best known is right here and that's Mount Tempo
00:09:44標高3543メートル
00:09:48そそり立つようにそびえる姿が観光客に人気のテンプルさんです
00:09:57So the mountains here are around at 3500 meters across on the side here
00:10:05富士山に匹敵するほどの高い山々の連なり
00:10:10カナディアンロッキーならではの絶景
00:10:15どのように形作られたのでしょう
00:10:21The Rockies were formed when the tectonic plate pushed against each other and pushed high
00:10:26Last glaciers through here were 10,000 years ago
00:10:30and that's what formed the valleys that we're in right now
00:10:34So before that they would have been there but it would have looked very different than now
00:10:40ロッキー山脈が形成されたのは今からおよそ6000万年前
00:10:48プレートの衝突によって大地に加わる力
00:10:53そのパワーが地面を隆起させたと考えられています
00:10:59そして260万年前から氷河期が始まり
00:11:04山脈は氷河に覆われました
00:11:08その後地球の気温は激しく変動したため
00:11:12氷河は交代と拡大を繰り返し幾度となく山を削ります
00:11:22それが100万年以上繰り返され
00:11:25現在の深い谷と切り立った山並みが作り出されていきました
00:11:35カナディアン・ロッキーは
00:11:37江戸に訪れるすさまじい寒さと温かな気候の中
00:11:42生み出された絶景だったんですね
00:11:49深い渓谷には今もその名残が
00:11:52例えばこちらビクトリア氷河です
00:12:07渓谷の底を走るハイウェイを通り
00:12:10氷河に削られた壮大な絶景を間近に見てみましょう
00:12:22ロッキーの大きな城のように見えます
00:12:52ロッキーの大きな城のように見えます
00:13:22ロッキーの大きな城のように見えます

00:14:12ロッキーの大きな城のように見えます
00:14:15ロッキーの大きな城のように見えます
00:14:19私のお気に入りの場所はここです
00:14:22アブラハム湖です
00:14:48実に不思議な光景です
00:15:00面積は54平方キロメートル
00:15:04日本の戸惑湖と同じくらいの大きさです
00:15:11ターコイズブルー一色に染まる湖
00:15:15鮮やかな色彩の正体は何なのでしょうか
00:15:27いやすごい!
00:15:29いや、なんか青緑というかすごい綺麗な色をしてますね
00:15:36多くの湖はこの色になっていますが
00:15:38私はこれが一番美しいです
00:15:41多分私のお気に入りです
00:15:43少しだけ見えますが
00:15:46実際は35キロメートルの長さです
00:16:04今度はペットボトルですくってみます
00:16:13色は緑じゃないですね
00:16:15普通の水というかちょっと濁ってますかね
00:16:25驚いたことに
00:16:27湖に流れ込む川もターコイズブルーです
00:16:31一体どういうことなのでしょう
00:16:36And if you want to, we can go up to the headwaters and see why it's that color
00:16:44色の謎を解き明かす湖の水源はここから20キロ遡ったところに
00:16:53Hiking, it'd be a couple of days
00:16:55But if we take the helicopter, we can get there in about 15 minutes
00:16:59Okay, which one?
00:17:01Let's take the helicopter. That'll be a lot quicker too
00:17:05Okay
00:17:14エリコプターで湖に流れ込む川を遡ること15分
00:17:26目的の場所に到着したようです
00:17:32ふぅ、もう着きましたね
00:17:36ここは標高3300メートルを超える山の山頂付近
00:17:45So here we're at the base of the Klein Glacier
00:17:49And in front of us, right now it looks more like snow
00:17:52But this is the Klein Glacier and here is part of the headwaters
00:17:56One of the headwaters of Abraham Lake
00:18:00クライン氷河
00:18:03The Klein Glacier
00:18:05ここから溶け出した水がアブラハム湖に注ぎ込むのです
00:18:11でもターコイスブルーの色とどんな関係があるのでしょうか
00:18:21You can see here, and you can see on here
00:18:25All of the straight lines going this way
00:18:28And those are just evidence from when the glaciers are moving
00:18:31And it's scraping on the rocks
00:18:33And then it's leaving all these straight lines behind on here
00:18:37ふぅ、なんかヤスリで削ったみたいな
00:18:43氷河は1年に数十メートルから数百メートルのスピードで動き続けています
00:18:51その時、重い氷河が岩盤を削り
00:18:55大量の砂や岩の粉を生み出します
00:19:01And if you rub your fingers on, you'll see a little bit of that rock flower
00:19:11確かに、結構強く擦ると指真っ白になりますね
00:19:17指真っ白になりますね
00:19:20It's really, really fine
00:19:23And this is what is giving the color to the lakes like we've been looking at
00:19:32岩の粉はロックフラワーと呼ばれます
00:19:37その一粒は千分の二ミリほど
00:19:41目では全く見えないほどの細かさです
00:19:47雪溶け水にロックフラワーが入り込むことで
00:19:51湖がターコイズブルーに輝くというのです
00:19:57This rock flower, when it's in the water, it changes how the light is refracting on the lake
00:20:03And that's why, depending on how much there is in there
00:20:06It changes the color from a lighter blue to a more turquoise
00:20:11太陽光に含まれる様々な色の成分
00:20:17それが湖の中の岩の粉にぶつかると
00:20:22青や緑色が激しく散乱されます
00:20:26そのため、人の目には湖の色がターコイズブルーに見えるのです
00:20:34And you can see Abraham Lake right there
00:20:38And all of this water going all the way there
00:20:41Giving it its majestic color
00:20:43Making it look amazing right down at the end of the valley here
00:20:51氷河が生み出す色鮮やかな湖
00:20:57カナディアン・ロッキーの美しさを一層引き立てる
00:21:02神秘の絶景です
00:21:14The summer is gorgeous, but winter is my favorite season
00:21:18And there's something quite special on Abraham Lake in the winter
00:21:22It's just something that you only see in a few places in the world
00:21:26And it's quite magical to stand on the ice there
00:21:33過去5年間でこのあたりの夏の最高気温は31度
00:21:40一方冬はマイナス45.8度
00:21:45その時湖は姿を変え幻想的な光景が現れるといいます
00:21:52それは一体?
00:21:56February, Abraham Lake on Lake Gokkan
00:22:00February, Abraham Lake on Lake Gokkan
00:22:10It's that thing
00:22:13I can see it now
00:22:18It's so cold
00:22:25真っ白ですね
00:22:28夏と全然景色が違いますね
00:22:35ターコイズブルーに輝いていた夏とはうって変わり
00:22:40白銀の世界となったアブラハム湖
00:22:47一年のうち4ヶ月も全面凍結するといいます
00:22:54ゴッカンのこの時期は湖の上を歩くことができるんです
00:23:11湖上に冬ならではの絶景を見つけ出しましょう
00:23:24凍りの上を歩いていますね
00:23:30人が乗ってもびくともしません
00:23:34凍りは相当分厚そうです
00:23:38これなんかすごい綺麗ですね
00:23:47本当だ!
00:23:49凍りの中に木の枝のような造形が
00:24:04夜気温が下がると凍りは収縮し亀裂が入ります
00:24:10そこに日中溶けた水が入り込み夜再び凍結
00:24:17その凍りが霜柱のように成長し不思議な模様を描き出すのです
00:24:29さらに進むと
00:24:42凍りの厚さは60センチ
00:24:45まるでガラスのような透明度です
00:25:05え!?マイナス45度!?
00:25:09その気温でできた絶景って何でしょう
00:25:16Look at this here
00:25:19綺麗ですね
00:25:22大きいのや小さいのや凍りの下で模様になっています
00:25:29確かに凍りの中に何かが埋まっているように見えますが
00:25:36凍りの下から見るとその姿がはっきりわかるといいます
00:25:50分厚い凍りに穴を開け水中ドローンで覗いてみましょう
00:26:05凍りと格闘し続けること1時間
00:26:11ようやく貫通
00:26:35では貫通しましょう
00:27:05♪♪
00:27:14♪♪
00:27:24♪♪
00:27:34♪♪
00:27:44♪♪
00:27:54♪♪
00:28:05♪♪
00:28:15♪♪
00:28:25♪♪
00:28:35♪♪
00:28:45♪♪
00:28:55♪♪
00:29:05♪♪
00:29:15♪♪
00:29:25♪♪
00:29:35♪♪
00:29:45♪♪
00:29:55♪♪
00:30:05♪♪
00:30:15♪♪
00:30:25♪♪
00:30:35♪♪
00:30:45♪♪
00:30:55♪♪
00:31:05♪♪
00:31:15♪♪
00:31:25♪♪
00:31:35♪♪
00:31:45♪♪
00:31:55♪♪
00:32:05♪♪
00:32:15♪♪
00:32:25♪♪
00:32:35♪♪
00:32:45♪♪
00:32:55♪♪
00:33:05♪♪
00:33:15♪♪
00:33:25♪♪
00:33:35♪♪
00:33:45♪♪
00:33:55♪♪
00:34:05♪♪
00:34:15♪♪
00:34:25♪♪
00:34:35♪♪
00:34:45♪♪
00:34:55But probably it's because of some of the organisms that live there.
00:35:01You think of very, very harsh environments.
00:35:05This is a harsh environment.
00:35:07And so not very many organisms can live there.
00:35:11If there's a lot of organisms present,
00:35:13then there'll be an intense color.
00:35:15If there's less present, less intense color.
00:35:19♪♪
00:35:22♪♪
00:35:32♪♪
00:35:42♪♪
00:35:52♪♪
00:36:02♪♪
00:36:12♪♪
00:36:22♪♪
00:36:32♪♪
00:36:42♪♪
00:36:47We have to respect that.
00:36:49I mean, it is a scientific curiosity.
00:36:53But it's more important to respect the culture.
00:36:57And so, no, I don't have plans to study further Spotted Lake.
00:37:02♪♪
00:37:10♪♪
00:37:18♪♪
00:37:26♪♪
00:37:31♪♪
00:37:36♪♪
00:37:44♪♪
00:37:59Yeah, it is.
00:38:00This park is known for beautiful lakes,
00:38:03wild rivers, birds, nature.
00:38:06It's a beautiful place to be.
00:38:08I'm so glad you're here.
00:38:14I'm looking forward to it.
00:38:22Wow, it's amazing.
00:38:24It's an amazing waterfall.
00:38:27Wow, it's so tight.
00:38:32Wow, I can't open my eyes.
00:38:35It's scary.
00:38:37Wow.
00:38:40Wow.
00:38:44♪♪
00:38:47♪♪
00:38:54♪♪
00:38:59♪♪
00:39:04♪♪
00:39:08Ari, look at this.
00:39:10Isn't this an amazing cliff?
00:39:13What do you think from that cliff?
00:39:17The height of the cliff is 200 meters.
00:39:22It is said that all of this
00:39:24is a volcanic rock that has been frozen by lava.
00:39:33We're actually standing on top of a lava flow.
00:39:37This flow, by the way, like you see it here,
00:39:39it's right here.
00:39:41It's all the way over there.
00:39:43So at one time, it covered the whole valley.
00:39:47It was not one lava flow, but many lava flows.
00:39:50So it took place over probably, you know, 100,000 years.
00:39:57The volcanic activity began about 350 million years ago.
00:40:03For many years, small-scale eruptions
00:40:06occurred in various places.
00:40:08And because there was little stickiness of the lava,
00:40:11it was impossible to make volcanoes.
00:40:13A flat lava plateau was formed.
00:40:21It is said that if you climb the observatory,
00:40:23you can experience that scale.
00:40:28Oh, it's a nice view.
00:40:31And now you can imagine this being dropped down,
00:40:34being a big plateau,
00:40:36being a big plateau,
00:40:38all flooded with lavas like the kind that we saw.
00:40:44The vast land was created
00:40:46by the constant flow of blazing lava.
00:40:51Now it is covered by lush greenery,
00:40:54but the lava land fills up
00:40:56the entire Shuritsu Park,
00:40:58which is twice as large as Tokyo.
00:41:06The one that's really of interest and stands out
00:41:10is Pyramid Mountain.
00:41:12You can see Pyramid right on the other side
00:41:14of these trees.
00:41:19Pyramid Mountain was formed
00:41:21underneath the glacier.
00:41:23It was formed by lava just flowing
00:41:25kind of flat over the plateau.
00:41:28And subsequently, you have a big pile of glacier,
00:41:32but the volcanism, the volcanic activity
00:41:35continues.
00:42:05The glacier, by the way, here,
00:42:07it's like a mountain.
00:42:09It's like a mountain.
00:42:11It's like a mountain.
00:42:13It's like a mountain.
00:42:15It's like a mountain.
00:42:17It's like a mountain.
00:42:19It's like a mountain.
00:42:21It's like a mountain.
00:42:23It's like a mountain.
00:42:25It's like a mountain.
00:42:27It's like a mountain.
00:42:29It's like a mountain.
00:42:31It's like a mountain.
00:42:33The glacier, by the way, here,
00:42:35was about 2 kilometers thick
00:42:37at its maximum.
00:42:39So imagine that, being under
00:42:412 kilometers of ice,
00:42:43sticking out.
00:42:45The very top was sticking out
00:42:47above the glacier.
00:42:49If you were standing here,
00:42:51you would be under ice.
00:42:55And then, 10,000 years ago,
00:42:57it melted, and there was
00:42:59a horrendous flood of water.
00:43:01Over this plateau.
00:43:27I know, I know.
00:43:29This is really the icon
00:43:31of Wales Great Park.
00:43:33People are coming from all over
00:43:35the world to see it.
00:43:59The amount of water here
00:44:01is 100,000 liters per second.
00:44:03500 times more than
00:44:05the amount of water
00:44:07in a family's bath.
00:44:17The cliff surrounding the waterfall
00:44:19is a volcanic rock
00:44:21that has solidified.
00:44:23It has become a deep warning
00:44:25due to the strong current
00:44:27of the glacier.
00:44:33Ice and fire
00:44:35coming together to make
00:44:37this spectacular scene.
00:44:39So imagine
00:44:41if we could go back
00:44:43almost half a million years ago.
00:44:50Does that make sense?
00:44:52Can you kind of picture that in your mind?
00:44:54So we're looking here at something
00:44:56that's a scene that formed
00:44:58over almost half a million years.
00:45:00That's a long time.
00:45:06And then,
00:45:08Nancy Hakshi told us
00:45:10something interesting.
00:45:12In winter,
00:45:14an unimaginable natural
00:45:16object appears
00:45:18in this waterfall.
00:45:20Almost like
00:45:22a snow cone
00:45:24around the bottom
00:45:26of the falls.
00:45:28And to me,
00:45:30that's when it's at its
00:45:32greatest beauty.
00:45:34I think it's
00:45:36fantastic and
00:45:38it's very dramatic.
00:45:43The highest temperature
00:45:45in summer is 45 degrees.
00:45:47In winter,
00:45:49it can cool down
00:45:51to minus 32 degrees.
00:45:55What does
00:45:57an ice cone
00:45:59look like
00:46:01in winter?
00:46:08The end of February.
00:46:13Our winter guide
00:46:15is a local nature guide,
00:46:17Chris Griffard.
00:46:26Welcome to Helmican Falls,
00:46:28our premier winter
00:46:30wonderland attraction.
00:46:40It's an ice cone.
00:46:47A giant ice tower
00:46:49appears to surround
00:46:51the flowing waterfall.
00:46:55Ice cone.
00:46:58An ice tower
00:47:00made of ice.
00:47:05How high is it?
00:47:07That right now,
00:47:09it's about 20 meters.
00:47:11It does get bigger,
00:47:13just as it gets colder,
00:47:15it builds up taller.
00:47:17It can get up to
00:47:1940 meters, probably.
00:47:21Really?
00:47:23Yeah.
00:47:2540 meters is
00:47:27equivalent to a 10-story building.
00:47:31It's an amazing
00:47:33gigantic structure
00:47:35created by nature.
00:47:37From the top,
00:47:41you can see
00:47:43the flowing waterfall
00:47:45being sucked
00:47:47into the ice cone.
00:47:53And then,
00:47:55a large amount
00:47:57of water splashes.
00:48:00Moisture coming off
00:48:02the waterfall,
00:48:04it freezes and creates
00:48:06a cone around the waterfall.
00:48:08And the fall,
00:48:10the mist,
00:48:12it's just perfect conditions
00:48:14for creating ice cones.
00:48:36The water
00:48:38flows through
00:48:40the ice cone.
00:48:44The water splashes
00:48:46freeze in an instant
00:48:48when they touch
00:48:50the edge of a round hole.
00:48:52The water splashes
00:48:54keep freezing
00:48:56and build up
00:48:58into a cone,
00:49:00creating a giant
00:49:02ice cone.
00:49:06In winter,
00:49:08the water splashes
00:49:10as much as
00:49:12the amount of water
00:49:14that flows through
00:49:16the ice cone.
00:49:18Even though
00:49:20the temperature
00:49:22of the water
00:49:24can drop to minus 30 degrees,
00:49:26the river never freezes
00:49:28and 26,000 liters
00:49:30of water flows
00:49:32every second.
00:49:34What is the identity
00:49:36of the huge amount
00:49:38of water
00:49:40that flows
00:49:42through the ice cone?
00:49:55To get more information,
00:49:57we headed to
00:49:59British Columbia University.
00:50:01Hello.
00:50:03She is a researcher
00:50:05at Elysee Lagars
00:50:07in Canada.
00:50:11I guess the most important
00:50:13thing is that
00:50:15the western coast of Canada
00:50:17is really close to the Pacific Ocean.
00:50:19And so that is essentially
00:50:21like a narrow filament
00:50:23of water that occurs
00:50:25in the jet stream
00:50:27that is bringing and drawing
00:50:29up from the tropics
00:50:31to hit BC where we see a lot of rain.
00:50:33In particular,
00:50:35one that we see causing
00:50:37a lot of precipitation
00:50:39is an atmospheric river.
00:50:41It is said that
00:50:43it rains a lot
00:50:45in this land
00:50:47in the cold winter.
00:50:49In most places,
00:50:51it rains more than
00:50:53600 millimeters
00:50:55from November to February.
00:50:58This is more than
00:51:00twice the amount
00:51:02of water that flows
00:51:04through the ice cone.
00:51:06The cause is
00:51:08the warm and moist
00:51:10atmospheric river.
00:51:12It is a layer of atmosphere
00:51:14that contains a large amount
00:51:16of water that extends
00:51:18from the tropical zone
00:51:20to the north and south.
00:51:22This is what causes
00:51:24warm heavy rain
00:51:26to hit the tropics.
00:51:28It is also called
00:51:30the Pineapple Express
00:51:32because it flows
00:51:34from the Pacific Ocean
00:51:36to land near Hawaii.
00:51:38Most atmospheric rivers
00:51:40hit,
00:51:42so we generally get
00:51:44about like 10 to 12
00:51:46a year.
00:51:48But we'll see most
00:51:50in like that November,
00:51:52December period.
00:51:54If it's from the tropics,
00:51:56then they're generally warmer,
00:51:58so they're going to fall as rain.
00:52:02The warm and moist air
00:52:04brought by the Pineapple Express
00:52:06hits the mountains
00:52:08and rises at once.
00:52:10It is suddenly cooled
00:52:12by the air in the sky
00:52:14and becomes a cloud
00:52:16and a lot of rain falls.
00:52:18Can and Dan
00:52:20fight each other in the sky.
00:52:22As a result,
00:52:24a large amount of water
00:52:26is brought.
00:52:28It is cooled instantaneously
00:52:30in the waterfall
00:52:32to create a gigantic
00:52:34structure.
00:52:42The atmosphere of the river
00:52:44Pineapple Express
00:52:46In order to experience the river, the Pineapple Express, we head to the coast facing the Pacific Ocean.
00:53:04Wow! The waves are amazing!
00:53:46And we've got to get ourselves back to the top.
00:53:56Well, they've got a bomb beside you.
00:54:00I have come to lose the smile.
00:54:04And I feel myself echoing.
00:54:08Something turning.
00:54:16Canada's nature is portrayed in the battle between the Canes and the Danes.
00:54:26The conflict has created a spectacular landscape in the Arctic.
00:54:38The destination is 800 km north of Calgary.
00:54:46The guide is Goddard, a naturalist.
00:54:54We head north, and...
00:55:01It's shaking more than before.
00:55:05It's all ice.
00:55:08It's a real winter road.
00:55:11Very slippery.
00:55:16This road is a winter road that can only be used in the cold winter of the Arctic.
00:55:22In the summer, it's a vast wetland.
00:55:28The ice is so thick that you can't drive.
00:55:34Every year, when it freezes completely, it becomes a road that connects inland.
00:55:46The road to Calgary
00:55:53Do you want to touch?
00:55:56Yes.
00:55:57See, it's really slippery. It's all ice.
00:56:00It's hard.
00:56:02It's all frozen.
00:56:04In the winter, we're lucky. It's frozen, it's solid, ready to drive on.
00:56:09But in the summer, we couldn't be driving here at all.
00:56:16For the locals, this road is a special winter road.
00:56:22It's minus 50 degrees.
00:56:25It's a winter gift from the Arctic.
00:56:34Two hours on the winter road.
00:56:38So we just arrived to the area I want to show you.
00:56:42Yeah, it should be really exciting.
00:56:45From here, we'll put on our snowshoes and walk to the scenic spot.
00:57:00It takes 30 minutes to walk on the snow.
00:57:06It's getting pretty hot.
00:57:10There are no trees around here at all.
00:57:14Yeah, now we arrived exactly where I want to show you.
00:57:18It's a huge snowfield.
00:57:23There are no trees around here at all.
00:57:28A huge snowfield has appeared.
00:57:32It's a beautiful view.
00:57:35It's a beautiful view, but there's a secret.
00:57:54Mr. Jashin started digging snow.
00:57:59Then...
00:58:03This is the sand.
00:58:09What? Desert sand in the Arctic?
00:58:13What's going on?
00:58:19Wow, it's so smooth.
00:58:23It's frozen, but it feels like desert sand.
00:58:30There's sand everywhere under the snow here.
00:58:33It's just covered with sand under the snow.
00:58:39It's amazing.
00:58:41I can't believe there's desert here.
00:58:47Please come back in the summer.
00:58:49It's going to be awesome to discover this beautiful, mysterious place and learn how it works and how it's been formed.
00:58:58It's 58 degrees in the north.
00:59:01It's located in the Arctic, which is the same latitude as Russia's Kamchatka Peninsula and Alaska Peninsula.
00:59:10In winter, it's about minus 50 degrees.
00:59:13In summer, it's about 40 degrees.
00:59:17This snowfield is said to turn into a desert.
00:59:22Is it true?
00:59:29The end of June.
00:59:34There is no way to access the ground.
00:59:41So I'm going to the snowfield in the air.
00:59:47It's been about two hours.
00:59:51I can see something.
00:59:57Wow, it's amazing.
01:00:00The snowfield has changed completely.
01:00:03As far as I can see, it has turned into a world of sand.
01:00:08This is the Asabaska Desert.
01:00:13The annual precipitation is about 300 mm, so it's not classified as a desert.
01:00:20But it still looks like a desert.
01:00:28The snowfield has changed completely.
01:00:31As far as I can see, it has turned into a world of sand.
01:00:36The area is about 300 square kilometers.
01:00:40It's about half of Tokyo's 23 districts.
01:00:48It is said that it is extremely rare in the world for such a vast land of sand to spread to the Arctic.
01:01:05Wow, it's vast.
01:01:22The guide for the summer is the nature guide, Colin Fry.
01:01:30It's hard to walk.
01:01:33It's slippery.
01:01:39It's very smooth.
01:01:42It's amazing.
01:01:45It's very smooth.
01:01:47It's like sand in the desert.
01:01:50It's very fine sand.
01:01:54It looks like we're in the Sahara Desert.
01:02:04It's a desert as far as I can see.
01:02:10The scenery hasn't changed at all.
01:02:13I have no idea where I am.
01:02:17It's a real desert.
01:02:22The sand dunes continue forever.
01:02:26However, there was an unexpected sight waiting for us.
01:02:34Wow, it's amazing.
01:02:36It's a beautiful view.
01:02:38We made it to the beautiful William River.
01:02:41What do you think?
01:02:43Wow, the forest.
01:02:46Wow, a stream of river runs through the desert.
01:02:51A green forest spreads around it.
01:03:00Wow, it's beautiful.
01:03:05It's a beautiful brown gradation.
01:03:10It's like a portrait.
01:03:15It's beautiful.
01:03:23You can see how it's kind of a light tan.
01:03:27That means that the water is very shallow.
01:03:30Where it looks black, that's the deepest water.
01:03:34And it's caused by the sand.
01:03:36The sand that's in the river is giving it the color.
01:03:41The sand at the bottom of the river reflects the sunlight.
01:03:45And the depth of the sand creates a beautiful gradation.
01:03:59How was the Asabasca Salmonidae born?
01:04:11The clue to the secret is at the end of the river.
01:04:18Okay, let's go.
01:04:23Cold river.
01:04:26It's cold.
01:04:30It's cold.
01:04:33There's sand at the bottom of the river, and the pattern is beautiful.
01:04:39It's a sight you've never seen before.
01:04:47It's a beautiful pattern of clear water and fine sand.
01:05:03It's deeper than I thought.
01:05:06My feet are getting caught in the sand.
01:05:11It's hard to walk.
01:05:15He's soaked to his waist in the water, and he's crossed the 100-meter-wide river.
01:05:24He somehow made it.
01:05:33He's walking through the desert again.
01:05:44Is this a lake?
01:05:50It was a huge lake.
01:05:55It's 7,850 square kilometers.
01:05:59It's 12 times the size of Biwako.
01:06:06And this lake is related to the birth of the desert.
01:06:16This was a big glacier.
01:06:18And when the glaciers melted, it formed Lake Athabasca.
01:06:23When the glaciers were here, they ground all the sandstone up.
01:06:29And created the sand.
01:06:31And then as the lake went down, it exposed the sand,
01:06:36and then the wind has blown the sand into the dunes.
01:06:40So, Athabasca sand dunes were made by glaciers.
01:06:46When this area was covered by huge glaciers,
01:06:50the land was scraped off, and a large amount of sand accumulated at the edge and below.
01:06:58Approximately 12,000 years ago,
01:07:01when the ice age came to an end and it became warm,
01:07:04the glaciers melted and water flowed out,
01:07:07and many lakes were formed at the edge of the glaciers.
01:07:14A large amount of sand was deposited at the bottom.
01:07:199,000 years ago, when the temperature rose rapidly,
01:07:24the water in the lake cooled down,
01:07:27and the fixed sand was exposed.
01:07:30The Athabasca sand dunes were born.
01:07:49This is amazing!
01:07:52This would have to be the most scenic place on the dunes, wouldn't you agree?
01:07:56And you have this ridge, it looks like we're in the Sahara Desert.
01:08:02Wow!
01:08:04It's beautiful!
01:08:18The sand dunes were formed by the ice age and the warm climate.
01:08:32The Athabasca sand dunes are traces of the battles between the Kandans from ancient times to the present.
01:08:48The Athabasca Sand Dunes
01:08:56Canada in winter again.
01:09:01The final destination is the western side of the Rocky Mountains,
01:09:05the Revelstoke.
01:09:10The annual snowfall is more than 12 meters.
01:09:19It is also known as the holy land of skiers.
01:09:26It is said that terrible natural phenomena occur here.
01:09:33First, let's find out what they are.
01:09:41We came to a ski resort.
01:09:45There are quite a few people here.
01:09:53I'm from England.
01:09:55Just for a bit of fun, just to get to slide around in the mountains, have a good time.
01:10:00The snow after this storm is super light and fluffy,
01:10:04and there's still a lot of untouched stuff that you can find wherever you ski.
01:10:09It's really fun.
01:10:12Revelstoke is known for its powder snow.
01:10:18This light and soft snow is associated with the phenomenon of terror.
01:10:31A meeting with a Revelstoke guide in the middle of the mountains.
01:10:41Revelstoke
01:10:47Amazing.
01:10:49It's a world of white snow.
01:10:55The cameraman, Frank DeRogier, who lives in this town,
01:10:59suddenly appeared.
01:11:02Welcome, welcome, Revelstoke.
01:11:05But what makes this place so different is the snow is like champagne powder.
01:11:10It's very light and very low density and just beautiful for skiing.
01:11:27So this is the champagne powder. Try it.
01:11:32And it is so beautiful and this is what people come for.
01:11:36This is the white gold in Revelstoke.
01:11:40Let's go.
01:11:43Let's go.
01:11:44Powder snow that captivates skiers from all over the world.
01:11:52It is the coldness of the ground that produces fine and low-moisture snow.
01:12:01This is the snow.
01:12:07The terrible phenomenon that this snow causes is...
01:12:32Revelstoke
01:12:34Revelstoke is actually a flood-stricken area.
01:12:3917 people have died in the past five years.
01:12:50I've been in a huge avalanche.
01:12:53And I lost my best friend in an avalanche.
01:12:57And I broke every bone in my body and had to be evacuated by search-and-rescue.
01:13:06Frank, who is a cameraman, is concerned about the flood.
01:13:11Since the accident, he has been filming to convey his fear.
01:13:17He has arrived.
01:13:22Wow.
01:13:24The trees are all over the place.
01:13:27It's like the water of the river in a flood.
01:13:33The weight of the 1-meter-wide snow is 600 to 800 kilograms.
01:13:39Such a lump of snow slides down at a speed of up to 200 kilometers per hour.
01:13:51This was very, very scary.
01:13:55This is kind of like the world we live in.
01:13:58In order to reduce the damage caused by the flood, various measures have been taken in Revelstoke.
01:14:10This is a weather forecast center.
01:14:16In order to ensure the safety of residents and tourists, the government and the military have cooperated to implement flood prevention measures.
01:14:28Just over here.
01:14:33It starts at 8 o'clock in the morning after everybody's been here for about an hour.
01:14:38And we've had somebody go to our weather plot and do a morning weather reading
01:14:42and determine if there is any new snow that fell overnight and how that snow is bonding to the existing snow.
01:14:47And based on all those inputs, we'll generate a hazard forecast for the next operational period.
01:14:57Based on the weather data, we determine where there is a high possibility of a flood.
01:15:06Temporarily block roads.
01:15:10Ensure the safety of cars and people, and create a small artificial flood.
01:15:18The method is...
01:15:27...to throw a typhoon into the snow.
01:15:32Before a major flood occurs, the snow is removed to prevent a major flood.
01:15:43The Trans-Canada Highway, which passes through Revelstoke's flood-affected areas,
01:15:49is an important road connecting Calgary and coastal cities.
01:15:58On the other hand, in order to avoid flooding,
01:16:03the implementation of artificial flooding must be carried out carefully.
01:16:09One hour of closure time is roughly $3 million impact to the Canadian economy.
01:16:16So it's very important that we minimize the amount of time the highway remains closed.
01:16:21That is the reason for our avalanche control forecasting program.
01:16:27So we have a group of technicians who are dedicated to assessing the weather on a daily basis,
01:16:33venturing into the backcountry to assess the snowpack and the stability of the snowpack.
01:16:40It's an important forecast for the country's economy.
01:16:44The forecast for a major flood.
01:16:47There is a Japanese man who has been involved in this mission for 20 years.
01:16:54Tomoaki Fujimura.
01:16:57He was checking the snow condition on this day as well.
01:17:03What I'm doing now is to find the difference in density.
01:17:12Floods are caused by three layers of different densities.
01:17:18The hard, ice-like, slippery surface.
01:17:22On top of that, the weak layers, where the condensation of the crystals is weak and fragile.
01:17:28On top of that, a large amount of fresh snow accumulates.
01:17:33When these three layers are combined, a high probability of flooding occurs.
01:17:40This is the soft layer.
01:17:43This is the kind layer.
01:17:46It's done with the same force, right?
01:17:49And when it comes to this, it goes in.
01:17:52This is the weak layer.
01:17:55And underneath that is the hard, slippery surface.
01:17:58The hard layer is the slippery surface.
01:18:05These three layers are the result of a fierce battle between the South and the West of Canada.
01:18:15There is a phenomenon called the Pineapple Express.
01:18:19It's when the heat from the snow comes in and the warm air and the wet rain fall on top of it.
01:18:26This is how the snow melts and forms the slippery surface.
01:18:33The slippery surface is like a smooth, ice-like state where the melted snow is re-frozen.
01:18:41It's made by the rain from the warm Pineapple Express.
01:18:46After the snow accumulates on top of the slippery surface, the weak layer is said to be formed when a strong, cooling, sunny day continues.
01:19:00It's called the hard layer, but it weakens the binding force.
01:19:04This is the weak layer.
01:19:07After the snow accumulates on top of the slippery surface, a strong, cooling, sunny day continues.
01:19:13This is the hard layer.
01:19:16After the snow accumulates on top of the slippery surface, the weak layer is said to be formed when a strong, cooling, sunny day continues.
01:19:25After the snow accumulates on top of the slippery surface, the weak layer is said to be formed when a strong, cooling, sunny day continues.
01:19:41This is a huge flood that occurs due to the unique coldness of the south-western part of Canada.
01:19:52To avoid this, people in private homes also carry out man-made floods.
01:19:57In this case, people are asked by a forestry company to carry out man-made floods to prevent damage to the forest.
01:20:17A few days later, they decided to participate in the decisive moment of the floods.
01:20:27Cameraman Frank also recorded the moment of the floods with a drone.
01:20:40The day of the floods has come.
01:20:45The place where the floods occurred is 30 km east of Revelstoke.
01:20:58At 8 o'clock in the morning, the staff has gathered.
01:21:04They have already contacted the relevant authorities, and people and cars are not allowed to enter.
01:21:15This is Mike Smallwood, who is in charge of the site.
01:21:27Because we're concerned that there's avalanches that could affect the road where the forestry workers are driving.
01:21:35So we'll do that by taking the explosive charges and putting them on the ridge top, blowing up the cornice,
01:21:42and then hopefully the cornice comes off and takes the volume of snow off the slope with it.
01:21:49There is 5 meters of snow on the top of the hill.
01:21:54The goal is to remove this and protect the forest road running under the mountain.
01:22:05The method is not a cannon, but an explosive.
01:22:10They approach the mountain by helicopter, detonate explosives, and cause a flood.
01:22:19The weight of one explosive is 12 kg.
01:22:23It is said to have the power to blow up 10 meters around the area.
01:22:32Penny Goddard is the one who detonates these explosives.
01:22:48Or at all.
01:22:54The helicopter has taken off.
01:22:57What kind of sight can we see?
01:23:05There are 9 cameras, including 3 of Frank's drones.
01:23:10OK, launching.
01:23:18The helicopter approaches the first crossing point.
01:23:36In order to effectively remove the snow, the explosives must be dropped at the correct point.
01:23:44The detonator is activated.
01:23:53The explosives have been dropped.
01:23:58The helicopter approaches the second crossing point.
01:24:08The helicopter approaches the third crossing point.
01:24:14The helicopter quickly leaves the place.
01:24:21And then...
01:24:24Oh, it exploded.
01:24:31Wow, amazing!
01:24:34Along with the loud explosion, a mass of 500 meters of snow has fallen.
01:24:44Wow, amazing!
01:24:47Wow, the snow!
01:24:50The snow is flowing!
01:24:55Wow, amazing!
01:25:03The altitude difference is 1100 meters.
01:25:07The snow falls at a distance of 30 seconds.
01:25:13Wow!
01:25:16Wow!
01:25:18Wow, amazing! The snow!
01:25:21The snow is falling more and more.
01:25:26In three hours, 12 explosives have been dropped.
01:25:33About 4,000 tons of snow has been removed.
01:25:46A terrible phenomenon.
01:25:49The phenomenon flows.
01:25:55On the other hand, it has also become an important role in connecting the world of nature.
01:26:12When avalanche paths continually log the trees that grow up in that area,
01:26:16it creates an area of green vegetation that provides food for different animals.
01:26:23Animals whose relationship with avalanche paths is totally beneficial.

01:26:55After the avalanche passed, the green grassland was spreading.
01:27:03Rocky mountains are full of trustworth.
01:27:08Because the trees were swept down by the avalanche, the sunlight shines and small flowers bloom.
01:27:25Yellow flowers are the favorite food of bears.
01:27:29Leaves and seeds are the precious possessions of herbivores.
01:27:36The simplicity unique to this land continues to support the ecological cycle that begins with the avalanche.

01:27:53From the ancient times to the present, the battle between the Kans and the Dans continues.
01:28:00It was depicting the roughness of nature and the landscape of life in the far north.
01:28:23The battle between the Kans and the Dans continues.
01:28:32The Kans and the Dans continue to fight the avalanche.
01:28:39The Kans and the Dans continue to fight the avalanche.
01:28:43The Kans and the Dans continue to fight the avalanche.
01:28:49The Kans and the Dans continue to fight the avalanche.
01:28:58Great Nature
