先週の雪崩事故、救助までの一晩
これだけの文面から、以下は私の想像です
おそらくノコギリが無かったので屋根を塞げるきちっとしたブロックまでは切り出せず、雪の壁の上にスキーや木の枝をかぶせてブロックを載せようと試みたのではないかな。隙間風などで寒く、あまり快適ではなかったので、周辺で雪洞を作れる十分な積雪と時間が十分あり、作った経験のある雪洞に結果的に切り替えたのでしょう。
“The possibility of using an igloo for emergency bivouacking.”
The night until rescue following last week’s avalanche accident
In a web article by the Japan Avalanche Network, based on interviews with involved parties, it was reported that following last week’s avalanche incident on March 14, 2024, on the northeast slope of Mt. Kohinata in the Hakuba Range, Nagano Prefecture, one member, unable to move due to a fracture, spent the night awaiting rescue, attempting to construct an igloo.
“Using nearby trees, skis, and snow, P2 created the structure but later moved into a snow cave, where they boiled water to spend the night.”
Although contact was established that day, harsh weather conditions prevented helicopter rescue until the following morning. It was essential to provide a place for the injured with a fracture to remain immobile for an extended period, considering the cold. The importance of being prepared to improvise with available tools and materials in such situations cannot be overstated. This epitomizes the essence and profound allure of mountaineering.
Based on this text alone, the following is my speculation
From this account, it seems likely that due to the absence of a saw, they couldn’t create tightly fitting blocks for the roof, so they attempted to cover blocks placed atop the snow wall with skis or tree branches. However, due to drafts and discomfort, they ultimately switched to a snow cave, benefiting from ample snow and time. If they had a saw, they might have managed to construct a more comfortable igloo with a draft-free roof. However, the decision to attempt building an igloo was still commendable.
A saw is not particularly heavy, and it greatly facilitates tasks like making a fire. Additionally, laying pine boughs collected with a saw as a bed for the injured person would provide comfort. Those on day trips for skiing or mountaineering might not typically carry a saw, but in Hokkaido University’s mountain club, we have always carried one alongside a shovel, even before the days of beacons and probes. They are affordable at around ¥4000-¥5000 and are a lifelong investment. I highly recommend having one, as they are useful not only in winter but also during summer outings.”
