Quite a mixed bag of snow surfaces on Tumalo Mtn today. Skinning up the west side at 9:30am I needed ski crampons for the last few hundred feet as the snow surface was a really firm melt freeze crust in places.
On the summit at 10:52am skies where broken with high cirrus clouds, no precipitation, no blowing snow, light west winds, air temp was 3c (37.4f)
Good spring skiing conditions skiing in the bowl with up to 10cm of ski penetration in loose wet snow producing pin wheels and rollerballs at each turn.
I did not see any signs of instability in terms of cornice fall, shooting cracks, or whumphfing.
