白馬大池の三角形(←割と通じる)を滑ろう!と6:30頃に家を出発。電動アシスト自転車で。スキーは珍しくプラブーツT4にそれなりのステップ板で。ゆえに装備が重い。アシスト自転車のバッテリーの減りっぷりで分かります。7:30栂池自然園からの歩き出し。天狗原まではもうスキーアクセスは終了ですね。登りも下りも歩きがおススメ。登山道の完全露出を100とすると今は60程でしょうか。天狗原には8:30に到着。ゆっくりと休んで9:00に動き出し。正面、白馬乗鞍岳の斜面をスキーで上がります。雲が流れており上がってる最中は真っ白け。雪面の状況は・・というと片手セルフィーにはキツイ程度に凸凹しております。そしていつものことですが白馬乗鞍岳山頂周辺には雪は無し。板をザックにぶら下げて歩きます。足もとはプラブーツのまま。んー、これが失策。。軽いスニーカーでもザックに入れとけば・・。あの岩伝いの歩きをガコンガコンしてるストレスはなかなかのものでした。。眼下には雪消え過程も美しい白馬大池。自然の造作に見とれてしまいます。三角の頂点には10:30の到着。天狗原から1.5時間、結構頑張りましたね。そしてこの三角も時期なりに凸凹コンディション。まぁもうすぐ7月だもんね。シールを外しながら自然園に降りられる斜面を覗きます。あー、行けそう。雪が繋がっているのは先日確認済み。よし、帰路はこっちで帰ろう!プラブーツで岩を歩くのも嫌だし。そして天狗原の斜面も滑るとこ無いし。うん、決定〜。の前に三角の真ん中を一本滑りましょー。今年も滑ることができました〜。さぁ登り返して次なるドロップへ。ここは長いよ。しかもやっぱりガリガリだしね。まそれでもヒリヒリする程には斜度が無いので淡々と。何度か休みながら無事中斜面まで。ふぅー。気が抜けたわけでも無いのだけれど足払いをくらったようにスリップ転倒〜。竹、ですよ。たった一本の細い竹。これに乗っちゃった。まんまと両スキーで、しかもいい角度でね。竹は滑るのよ・・。自然園の自転車まで無事到着。11:30でしたね。というわけで5時間の動きっぱなし。心地のよい疲労です。これで自転車の鍵が無い!?が無かったらパーフェクトだったんだけどなぁ・・・好事魔多し。。 2025年6月19日

Off to ski the "Triangle" of Hakuba Oike (← surprisingly, that term is actually understood!) ? I left home around 6:30 AM on an electric assist bicycle. For once, I took my plastic T4 boots and reasonably decent scaled skis. Naturally, that made the gear heavier. You could really tell by how fast the e-bike battery drained.

I started hiking from Tsugaike Nature Park at 7:30. Ski access up to Tenguhara is now effectively over ? hiking is recommended both up and down. If 100% is a fully snow-free trail, it’s probably around 60% exposed right now.

Arrived at Tenguhara by 8:30, took a relaxed break, and got moving again at 9:00. I skinned up the slope of Mt. Hakuba Norikura straight ahead. Clouds were drifting across, so it was completely whiteout while climbing. As for the snow surface ? let’s just say it was too bumpy for a one-handed selfie.

As always, the summit area of Mt. Hakuba Norikura was snow-free. I had to strap my skis to my pack and hike. Still in my plastic boots. Yeah… that was a bad call. I should have packed some lightweight sneakers. The clunky, stressful process of rock-hopping in plastic boots was no joke…

Below, Hakuba Oike was in the middle of its snowmelt ? a stunning sight. Nature’s sculpting at its finest.

I reached the tip of the Triangle at 10:30. Took about 1.5 hours from Tenguhara ? not bad, I worked pretty hard. Naturally, the Triangle slope was also bumpy with late-season conditions. But hey, July is just around the corner.

While removing my climbing skins, I peeked at the slope that heads down toward the Shizen’en (Nature Park). Looks like it’s doable. I’d already confirmed the snow was still continuous there the other day. Alright ? let’s take that way back. I really didn’t want to rock-hop again in plastic boots. And there’s nothing left to ski at Tenguhara anyway. Decision made!

…But first, one run down the center of the Triangle. Glad I got to ski it again this year!

Then I skinned back up for the next drop. This one’s a long haul. And, of course, still icy and crusty. Fortunately, the slope isn’t steep enough to make it too intimidating, so I just kept grinding away. Took a few breaks and eventually reached the mid-slope safely. Whew.

And then ? not because I lost focus or anything ? I slipped and fell hard like I’d been kicked out from under. The culprit? Bamboo. Just one skinny little stalk of bamboo. I landed on it with both skis, at the perfect angle. Bamboo is slippery...

Finally made it back to my bike at the Nature Park by 11:30. So that was a full 5 hours of constant movement. A satisfying kind of exhaustion. If only… I hadn’t lost my bike key! That would’ve made it a perfect outing. But alas ? good things attract trouble.
