Snowpack

AM laps were rough but the ski quality quickly improved. All slopes over 37 degrees produced sensitive storm slabs, slopes under 37 would crack and slide with some pushing. Some slabs broke up to 20" deep and 150' wide, running quite far but debris piles were small.

Every lap produced multiple storm slab avalanches. Last lap at 1600 in 2D -SS-ASc-D1.5-R2-I (20" deep, 175' wide running about 300 feet). Storm slabs got more sensitive as the day went, intense precip bursts of graupel/rime throughout the day quickly changed conditions. Averaged over 1" an hour for 8 hours today. Multiple repeaters today in Thortons, Way Long, Gerbil Shooter today. Thorton's SS-ASc-R1-D1-I PP (15cm x 25m x 75m)
