重要な層と弱層とテスト結果
Snowpack Coverage still thin. Easy to punch through to Haimatsu or Nanakamado once above treeline. Most terrain still below threshold with only isolated start zones around gully features. Surface is 20-25cm F on a settled base. HS 160cm above Hakuginso, less above treeline. Gullies not fully filled in yet.
Comments
Limited observations due to low coverage and short time period.
