積雪構造 HST 30-45cm remaining dry on polar, rapidly settled on solar above 2200m and formed a crust below. HST sits on top of previously settled dry snow on polar and on a sun crust on solar up to 2100m with a weak bonding leading to storm slab reactivity. Wind slabs suspected reactive on high ridges but snow remained mostly undisturbed below. At TL/BTL 230116MFcr is down 120-220cm and does not show signs of activity.
