On quick hand pits we were getting nice clean shears on that goo crust about 18" down, but it took a fair bit to get it to pop. When we and the party we entrained with skied we had some medium-sized sluffing, but no problems. Did yesterday's loading settle out quickly? didn't form a slab due to the trees? Even tho Argenta headwall is not necessarily "safe" per se due to the steepness and openness of the trees, it is a bit more protected than some of the more exposed lines, and I was glad that we were in Argenta vs bigger, more-alpine terrain.
