鈴蘭山の会の講習
北大山岳部の先輩から依頼のあった、鈴蘭山の会のイグルー講習会の講師に日程的にいけないので、代表3人に乗鞍岳来てもらって事前研修で特訓となりました。先輩はイグルーは何度も作っているけど、３時間かかる、１時間以内で作れるスキルを、とのことです。世界最速のイグルスキー式を体得してもらいました。
鈴蘭山の会は、何十年もある山岳会です。90年代には沢と山スキーで精力的に活躍していて、充実の報告書をバンバン出していました。私の世代の社会人クラブとしてBCの初期を作ったクラブのひとつではないかな。当時パソコン通信で知り合った鈴蘭の古本さんたちに、一度イグルー講習山行をしたことがありました。白鳥山から日本海へ滑りおりる山行でした。古本さんはその後、笊ヶ岳の沢で死んでしまった。
製作3時間→1時間に
やはり作った経験のある人は飲み込みが早く、長くてきれいなブロックを切り出して、１時間程で完成させました。スピードはやはりブロックの切り方をいかに磨くかです。立方体は一段囲んで終わり、早々に長いブロックを切り出します。
中心に3人用サロン、周辺に個人イグルーを３つ作ってトンネル連結です。先輩たちは一泊して明日は上を目指すとのこと。イグルスキーは、20分で滑り降りてバスで松本に帰りました。
晴れて風も弱く気持ちの良い天気だったけど気温は結構下がった。スキーぶっ飛ばして降りたら体が冷えた。とんかつと新潟の酒を買って帰りました。
An Igloo Workshop at Norikura – Organized for the Suzuran Mountain Club
I was asked by a senior member of the Hokkaido University Mountaineering Club to serve as an instructor for an igloo workshop organized by the Suzuran Mountain Club. However, due to scheduling conflicts, I couldn’t make it. Instead, three representatives from the club came to Norikura-dake for an intensive pre-training session. The senior member mentioned that while they had built igloos several times before, it took them about three hours each time. They wanted to learn how to build one in under an hour. So, I taught them the world’s fastest “Igloosky Method.”
The Suzuran Mountain Club has been around for decades. Back in the 1990s, they were very active in mountaineering and backcountry skiing, producing excellent activity reports one after another. I believe they were one of the clubs that pioneered backcountry skiing among social clubs during my generation. I once organized an igloo workshop expedition for Suzuran members I had met through PC communication networks back then. It was a trip that started from Shiratori-yama and ended with skiing down to the Sea of Japan.
One of those members, Mr. Furumoto, later passed away in an accident while climbing a stream on Mt. Zaru.
Reducing the construction time from 3 hours to 1 hour.
As expected, those with prior experience in building igloos picked up the technique quickly. They cut long, neat blocks and finished the igloo in about an hour. The key to speed lies in refining the block-cutting technique. Once the first layer of cubic blocks was completed, they swiftly moved on to cutting longer blocks.
We built a central igloo with space for three people to gather and connected it via tunnels to three smaller personal igloos surrounding it. The senior members planned to stay overnight and aim for the summit tomorrow. As for me, skied down , taking only 20 minutes to descend before catching a bus back to Matsumoto.
The weather was clear, with weak winds and a pleasant atmosphere, but the temperature dropped considerably. By the time I sped downhill on skis, my body was chilled.
On the way home, I bought tonkatsu and some sake from Niigata.
