This path off the shoulder of Cashmere ran very large and took out maybe a couple hundred trees 20-40cm+ in diameter, some previously live, some burnt. It looked like it widened the path a substantial amount. Debris was split at the bottom into a handful of tongues with large, wet chunks. The lower extent came to roughly 80' of the summer road right near the Eightmile TH, about 4,000ft vertical fall.Photo:

Observations
Widespread cycle on the mid-January crust in the Icicle from about Eightmile rd and west. Numerous D2-2.5s, many D3-3.5's and maybe a couple D4s. Crowns on all aspects and elevations over around 5.2k, some very wide. Between around 4.5 and 5.5k they were more like wet slabs that ran on the mid-Jan crust. Below that slides were initiating as deep loose wet, to the crust.
Medium sized surface hoar growing during the day. Solar aspects will have a suncrust, and may still have some surface hoar. Found the 2/22 melt freeze crust up to 5,000ft, with 30-40cm low density snow over it.
