Route Description: Afternoon snowmobile tour to Scarp Ridge, Beaver Ponds TH, and Horse Ranch TH documenting wet avalanche patterns from the last few days.
Observed avalanche activity: Yes
Avalanches: More wet action. In summary, all of the large (D2+) avalanche activity (both wet slab and wet loose) has been happening on east, south, and west aspects, mostly near and below treeline, where meltwater is most intense right now. I saw a few wet slabs break near 12,000′ into above treeline type of terrain. These were all on rocky, shallow slopes facing SE. There’s still plenty of wet loose activity happening on NE and NW aspects but it’s still shallow and not gouging like the southern side is, and no wet slabs on the northern half of the compass thus far.
Weather: Hot.
Snowpack: A quick handpit on a 30 degree, SE facing slope at 12,000 feet this afternoon had wet snow about 6″ deep and moistening snow below that. The snowpack was generally supportive to sledding near and above treeline with track pen about 6″. It was trapdoor in a few low-elevation areas.

Date of Observation: 04/11/2023
Name: Zach Guy
Zone: Northwest Mountains
Route Description: Morning tour into Peeler Basin, traveling mostly on northerly aspects to 12,000’
Observed avalanche activity: Yes
Avalanches: A few wet slabs on S to SE aspects NTL that ran yesterday, D1.5 to D3. Several large gouging wet loose BTL on SE and E. Plenty of shallow wet loose at all elevations (D1 to D1.5), spanning around to NE aspects at higher elevations and N BTL. More photos later tonight.
Weather: Clear, light winds. Waaaarm.
Snowpack: Marginal refreeze: punchy boot pen and supportive ski pen at 9 am. Felt like the window for good corn on SE was about 9:30 NTL. Still dry powder on high due north; Northeast ATL started rollerballing this morning. Bigger pinwheels as we descended to north BTL, and we triggered a few shallow wet loose involving just the white snow above the dust layer. North quadrant appears to be ways off from water draining into the snowpack for wet slab issues.

Route Description: Pavement observations
Observed avalanche activity: Yes
Avalanches: A handful more large Wet Loose and Wet Slab avalanches failed in the Red Ridge area. Wet Slabs seem to be the biggest issue on easterly and westerly aspects with more southerly slopes generally being a loose problem.
