翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tree well ： ウィキペディア英語版 Tree well A tree well is a void or area of loose snow around the trunk of a tree enveloped in deep snow. Also known as "spruce traps", these voids present danger to hikers, snowshoers, skiers, and snowboarders who fall into them. ==Formation== A tree's branches shelter its trunk from snowfall, allowing a void or area of loose snow to form. Low-hanging branches as on small firs further contribute to forming a tree well, as they efficiently shelter the area surrounding the trunk. Such wells have been observed as deep as 20 feet.〔(【引用サイトリンク】 accessdate=2014-12-07 )〕 They can also occur near rocks and along streams. Tree wells may be encountered in backcountry, on ungroomed trails, off-piste, and on ungroomed/piste boundaries. The risk of encountering one is greatest during and immediately following a heavy snowstorm. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tree well」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
