We had originally hoped to ski a north facing gulley, but the April persistent slab was thicker and stiffer than we expected, and still producing unstable test results, so we bailed from that terrain.  Wet loose avalanches were easy to trigger near and above treeline on southerlies this afternoon, entraining all of the recent snow (3" to 4" deep) down to the April 1 crust.  One of these wet loose avalanches triggered a persistent slab about a foot thick as it ran into east-facing terrain.  

Wet instabilities developed this afternoon with natural and skier triggered activity. No cracking or collapsing observed, but one wet loose triggered a persistent slab, and we also found propagating test results on the same layer.

On a NE aspect at 13,000', a stability test produced ECTP22 results on the April 1 faceted crust.  The slab was 50cm thick and mostly 4F, with a small amount of 1F.  I also found ECTPV results in a fresh windslab that probably formed in the past 24 hours. It was only 10 cm thick but 1F hard.  

The recent snow (above the April 1 crust) became wet throughout on south aspects ATL, and just the surface was wet on east aspects ATL.  The snow surface remained dry on northeast aspects ATL.  The buried April 1 crust remained frozen N/ATL.  Below treeline, there was negligible recent snow and no wet loose concerns in this location.  At these lower elevations, the exposed April 1 crust softened into nice corn and remained supportive to boot pen through the entire day.
