Natural cornice drop in West Monitor only produced a shallow sluff. New snow seemed mostly well bonded.

Dropped a fairly good size cornice into Scotts Bowl, got some cracking but no slide. Both West Monitor and Scotts have a stout wind slab capping the facets underneith, seems to me these wind effected slopes will hold more weight than the protected slopes with facets top to bottom. Which in turn means that they will require more weight to avalanche thus producing deeper and larger slides if we get enough snow to overload these slopes. Might take a cornice drop or the weight of a person to send them over the edge, guess it all depends on how much weight we get.

Of note also is the weak snow on the south end of the compass, where there is snow. Noted weak snow on SE and SW, crust facet sandwich. Took a look at SW facing slope about 9600ft out of the wind scoured zone pit revealed at least three deteriorating crust with large grained facets seperating them, crust under the new 2" was the stoutest but would crumble in your hand if you were not carful with it.
