重要な層と弱層とテスト結果
Snowpack 20-30cm HN sits on a variety of surfaces and crystal types. N-Erly terrain harbor 2mm SH, 1mm FCsf (rounding), 2mm PPgp. Southerly aspects hold a thin 1F-P MFcr, with 2mm FC Crust is harder where steeper. Wind affected areas with a 1F bed surface at 1900m were conducive to larger releases below todays HN.
