Broken Top Area
Ski or Snowboard
I toured on south, east, and north aspects on Ball Butte and on SE, S, and SW aspects on Broken Top. Previously formed shallow windslabs were observed on east aspects below ridgetops, but they were not reactive. I found no cracking and no slabs moving under my skis. The windslabs I observed are becoming well bonded to the older snow surfaces.
I observed very small skier triggered loose wet slides on a SW aspect above treeline (a la mode run on Broken Top). I observed no other signs of unstable snow and no other avalanche problems. I found great skiing on windward aspects that were softened by the sun and warm temperature.
I found remnants of surface hoar (on the surface) on southerly slopes near the base of Broken Top; it was decomposing and laying down.
Wind ranged from calm to light and out of the W and SW. Scattered clouds were present throughout the day. At noon at an elevation of 7800 on Ball Butte, the air temp was 1.5C (35F).
I encountered some very slick crust surfaces near ridgetops on Ball Butte.
