Quick report

Took a leisurely walk up above Marion to dig around on south aspects and get some views of the surrounding alpine terrain.

  • Observed one crown that looked relatively newer in the Dickey drainage. This crown failed just below ridgeline. It looked more recent than other nearby slab avalanche activity. 
  • Wet loose activity appeared a couple of days old. All D1-D1.5 in size. 
  • Surface conditions on south aspects softened by the time I arrived at noon. Surface snow was still semi-supportable to ski at around 3 pm.  Just starting to get manky. 
  • North aspects at upper elevation still held dry surface snow. 
  • Meltwater reached the January crust/facet layer on southerly aspects at 6000 feet.  Facets below the January crust are just starting to become moist.
  • I only found a few inches of wet snow above a crust on a southerly aspect near 7000 feet. This was however on a slope with roughly a 30-degree angle. I suspect steeper slopes that receive a more direct sun angle have more wet snow. 

There was still plenty of time for the sun to do its work after I left.

I'm guessing it was a hard slab. Failed just below ridgeline. Crown looked crisper than old crowns observed on Cameahwait.
