Kachina Peaks Avalanche Center

Dug by instructor and KPAC Level 1 Course. Average HS in this area was ~65 to 80cm. Note A: This ice layer was not ubiquitous in the snowpack. Appears to have formed during the warming and raining events during first few days of Feb 2021. Note B: Generally this depth hoar was 5-15cm think. Where measured for this pit it was 40cm deep between two boulders. Generally the depth hoar was only 5cm to 20cm thick. Generally, many boulders protruded into the 1f layer above the depth hoar. Note C: occurred where depth hoar was ~10cm thick and HS was ~75cm.

All depth measurements for layers and tests are approximate, +/- 4cm. Measurements and tests by James Foulks, Troy Marino, Ken Galinski

Extreme windloading. This was a pit within a windlip that was 194cm deep. 5m over from where the pit was dug was bare to rock.

Column tests isolated to 60cm. Based on visual clues and ski cut reactions, this structure appeared to end within 100-200 ft below location.

Column tests isolated to 140cm
