Morning started with broken skies transitioning to overcast. Light SE winds near and above treeline, moderate at times along alpine ridges. No precip.
Observed 5 old winds slabs all on north aspects and high in terrain (4560'-6000'). All believed to be natural from Saturday morning (March 4th) with one possible skier triggered. Of note, was one old wind slab seen lower in the terrain (4560') that pulled out 60m wide with a crown height up to 3'. Started in steep convexity but deeper crown (wind deposit) than expected that low on the slope (slope starts ~6200'). Also observed a bigger than typical cornice NE of Snoqualmie's E Summit. See photos and captions for more info.
Some cracking in wind deposited areas and minimal snow transport off summit ridgelines and over convexities above tree line. Still lingering wind slab concerns above tree line.
