This post is to supplement/confirm the observations of the other touring group on West Willow on 2/5/21. Whumphing was noticed as low as 4800', in the Boulder Creek drainage where the West Willow trail forks to the SE from the main trail. Like the other group observed, cracking occurred reliably (predictably, even) in any place with sparser tree coverage. The snowpack image shows the propagation potential, in the location of the GPS coordinate listed. Shears propogated sometimes up to 8m+ away from the skin track, but due to conservative travel, did not collapse nor slide. The second photo is of one of the two natural slides across drainage on the east side of Gold Hill. This was the smaller of the two, the northern slide. As stated by the other group, difficult to estimate the crown lengths from far away, but the southern larger avalanche looked like it propagated in the 30-40m range, northern perhaps in the 10-20m range.

Unfortunately observer did not budget enough daylight to dig a pit.
