The Day Was:
The Ride Was:
The Snow Was:
Mellow slopes Open trees
We Stayed Away From:
East aspect below Todd Ridge was skiing really well today. Looks like the slope received about 30cm (12") of the recent storm snow. The new storm snow seemed really well bonded to the old crust below giving hard results with hand shear tests.
I dug into the slope on the east aspect of Todd Ridge at about 6626', slope angle was 25 degrees. The old crust from before our most recent storm actually comprises two 1-2cm crusts, between which I found 0.5mm of rounding facets. On a compression test this layer of facets failed at CT20 RP.
On the North side of Soda peak I dug again finding a similar snowpack. here I performed an Extended Column Test on the facet layer of interest. Result was ECTN23, no propagation.
On top of Todd Ridge at 9:30 winds where calm, skies broken, air temp was -2c (28). There was no blowing snow and I did not see any cornice build up or wind slabs on my tour. Skiing slopes I did not experience any whumphing, did not see any shooting cracks on ski cutting, no signs of recent avalanche activity.
Leave Todd Lake at 1pm air temp had risen to 1c (34f) and tree bombs where falling from the trees on solar aspects.
A great day of skiing with a layer of interest to keep an eye on :)
