Problem #1 Comments
Solar effect becoming prominent on directly south facing slopes beginning around 11 am. There was a subcentimeter zipper crust irregularly distributed on these aspects that wouldn't make for fun riding. Small pinwheels were initiating on steeper slopes within the new snow but weren't gaining much steam.

Problem #2 Comments
Visibly largely confined to E-N aspects during our travel. Cornice drops and ski cuts onto SE slopes yielded no results. Didn't go near the pure easterly side of the compass.
Comments
Toured from Butler->Mill A->East shoulder of Raymond. Lower elevations are a mix of sun crusts and preserved dense powder. Some wind drifting onto the Southerly side of Baker pass but wind transported snow was limited to areas immediately below the ridgeline, and there was no cohesive slab formation. Southerly slopes are getting solar as noted above, but SE facing was well-preserved creamy powder. We were able to start some moderate loose snow sluffs on the steepest pitches of the chutes off of Raymond summit but these were predictable and not large in size. Multiple ski cuts and cornice drops produced no results and the riding was excellent.
Exited out Butler Basin from Gobblers. E facing head of the basin is heavily windloaded and extremely suspect. 45 degrees of the compass away on the SE aspect the snowpack was just 30-40cm deep, storm snow on ground. Skied well and again no evidence of instability.
Powder remains available in select locations. As we enter a dry period until Christmas it will be challenging to rein in the desire to jump onto E-NE slopes for lack of better snow, but we've made it this far, might as well let that basement layer heal up.
