Washington Gulch Check

CB Avalanche CenterCBAC Observations

Date of Observation: 01/05/2022
Name: Evan Ross

Zone: Northwest Mountains
Route Description: Primarily Elkton and Baldy Area

Observed avalanche activity: No
Weather: Bit breezy eh. Obscured sky and strong westerly wind. Mostly S-1 and light snowfall. Heavier rimed precip was accumulating as I headed out in the early afternoon.
Snowpack: Hard to measure new snow given all the wind. In a fairly sheltered area at 11,000ft, there was about 6″ new at 1pm. The new snow was very light and mostly getting blown away. I was able to find a couple of small test slopes where the new snow would produce some shooting cracks and holding up as a fresh wind slab. Otherwise, the snow has already been redistributed from the winds with old hard drifts having previously formed. More forecasted snow will provide more fuel for new wind slab development. It was real blustery out there at near and above treeline elevations and managing wind drifted snow was still one of the main concerns.

In the jet stream on Mount Emmons

CB Avalanche CenterCBAC Observations

Date of Observation: 01/04/2022

Zone: Southeast Mountains
Route Description: Standard Red Lady skin track from the Kebler TH to the Summit.

Observed avalanche activity: No
Avalanches:
Weather: Calm and pleasant at the trailhead. Air temps in the 20’s but wind chill must have been -20 at and above tree-line. Eric said on the radio this morning that the jet stream was going to be dipping in our direction; he was spot on, as it felt like we were actually in the jet stream! Sustained SSW winds in the 30-40mph range with gusts much higher than that. I got blown over once and stopped to brace myself several times. Ended up wearing a puffy and full buff on the climb near and above tree-line, which is rare for me…
Snowpack: We were hoping for some recycled powder in the bowl but were (un)pleasantly surprised to find a widespread and inpenetrable windslab throughout caused by strong down slope winds. I suppose the old tracks rising up and out of the snow should have been a clue. The best turns were down lower and anywhere there was a rippled texture to the snow surface. Although there was plenty of wind, there didn’t seem to be much available snow for transport: the ridges are quite scoured.
