Johnson canyon observations.

We toured multiple aspects on Peak 7,483 in Johnson Canyon this morning to look for surface wet snow formation on solar aspects in the 7,000' to 7,500' elevation range as well as to look at cornices and old wind slabs. As far as surface wet snow, we saw only very minor amounts of skier triggered roller balls that stayed small and did not grow in size while rolling downhill up to our departure from the area at noon.

Cornices were very large and many had collapsed this past week. Fissures 15 to 20 feet deep had formed in several areas behind cornices where they have separated from the ridgetop.

We saw the remains of several D1 wind slab avalanches from the Jan 3rd/4th avalanche cycle in this area in near treeline terrain on N and NE aspects. We chose one that had safe access and performed snowpit tests in both the crown and flank. We saw no evidence of any ongoing wind slab instability from the CTN and ECTX test results we obtained.
