Observations
At 8am on Sunday, April 11th, we started from Heather Meadows and arrived at the base of Mt. Ann just before 9am. Problems observed were significant cross loading, recent evidence of a wind slab release beneath Mt. Ann, as well as potential problems in glide cracks and wet-loose avalanches. 2cm of surface hoar were present on our approach, sagging/consolidating by the time we reached the saddle.
Our group did not witness any avalanches, but we did witness minor/manageable sluffing with our turns on N-facing slopes. While the majority of slopes did not show signs of instability, S-facing slopes on the saddle below Mt. Ann proved to release small soft slabs as we down-booted. In certain spots, these S-facing slopes also proved to be firm + steep and tricky to navigate without caution.
Winds were calm to non existent throughout the day, and we experienced little cloud cover until ~12pm. Solar radiation was well underway. Riding conditions were delightful for April; snow quality was fast and dry.
