Pacific Alpine Guides AIARE level 1 course. Companion rescue and test pit day with minimal travel.

Feb. 6, 2016, 2:15 p.m. PST

Weather: Calm- Light variable winds, broken clouds, 3500' FL, no precip.

Snowpack: We went looking for potential buried surface hoar, which as noted in the avalanche forecast, may be present in the area. We found a slope that had cracked significantly but not released, and chose to dig nearby. We found the buried surface hoar layer intact and reactive 25cm's below the surface. The HS in our pit was 227cm's. From 227 to 220 the snow was F hard and at 220 we found a P hard 2cm windslab. From 218 to 202 the snow went back to 4F hardness and the buried SH was found at 202cm's or 25cm's down. Below the BSH the snowpack was 4F-1F increasing density with depth until you hit the wet grains from the rain event at 185cm's.

Area Description: N aspect of the Hurricane Ridge Visitor Center area, west of the ski area. 5228'. UTM 10T 462770 5313178

Avalanches: We did not observe any avalanches, however we did see shooting cracks that spanned an entire slope and zippered between small trees. In our test pits we had positive shovel tap test results and a CTH 21 / Q2. Due to time constraints we did not perform any large column tests.
