This wet loose avalanche is a great example of where they often occur. Rocks absorb extra heat from the sun and can quickly melt and destabilize the snow. Either move under areas like this early in the morning (as we did), or if you have to travel under them later in the day, move quickly.

Toured out of beehive basin yesterday (4/22). I spotted a storm slab avalanche on a northeast-facing slope at 9400 ft It was fairly far away, but the debris pile was decently sized. While skiing a northwest aspect in the high alpine, I pulled out several small wind slab pockets, including one that propagated about 10 ft and was a foot or so deep. These slabs were beginning to set up and weren't super touchy. Later in the day, I saw a small point release originating from an east-facing rock band at around 10000 ft.
