Report from yesterday, Cayoosh:

Snow was right side up, knee deep in ne to nw.
Light crust on East slopes that was variable. I never went above treeline. Had sluffing on steeps on North faces, was on a shallow east face at treeline and had whumps, but nothing cracking or moving.
Someone saw me and said i was an inspiration. He said he hoped he'd be active when he's old! Sigh.
