Went up Zoa on Sat Jan 12. (minus) 15 at the parking lot in the morning but significantly warmer once in the sun. Lots of wind effect higher up with some hard wind slab in places. Skiing was best in the trees and low down. No sign of recent avy activity.
Sorry, no pictures right now, but maybe later...
Have fun!
Similar skiing conditions on Rainbow. Best skiing was subalpine zone.
