Ski or Snowboard
Groundhog Day? A day of sun, then a little snow... that's been the story of the last few days. A couple of inches (6 cm.) of new snow over yesterdays crust. The skiing was good where you could find smooth snow and no old tracks. I didn't see any signs of current avalanche problems along my tour (below treeline). It snowed lightly during the morning and then there were some sun breaks after noon that ruined the skiing on south slopes. It was at or slightly above freezing throughout my tour and generally calm with only an occasional light breeze from the south-west.
I dug a test profile on a north facing slope at 6520 ft. While I was able to find the buried surface hoar 65 cm. below the surface, it was not particularly reactive in this spot (CTH RP, and CTN). A shovel tilt tests failed beneath the uppermost crust down 20 cm., but there did not appear to be any persistent weak layers involved, (in the compression tests this had a fracture character of progressive compression).
On the ridge between Todd Lake and Soday Creek at 11:20, 6,540 ft.
The sky was overcast and it was snowing lightly
Temperature was 0 C
Wind was Calm with Light gusts from the south west and blowing snow was none
There was 6 cm. of new snow and boot pen. was 15 cm.
