Quick report

I took a quick trip up the Alpental Valley to Draft Dodger Ridge and Pineapple Pass to get one last feel for conditions ahead of the windy weekend.

As I approached Pineapple Pass, I found subtle wind-loading had already occurred. Textured surfaces, a drifted in skin track, localized cracking, and stiffer surface snow were all clues that the wind had been a player recently. On Draft Dodger, the typical convex rollovers looked to have been wind-loaded at some point.

There were also plenty of holes and rocks to manage throughout my travels. Getting from Great Scott Bowl into No Fog was a harrowing effort with no shortage of holes.

Overall, there's plenty of low-density snow available for transport this weekend, travel is improving but still below seasonal norms, and we have a messed up and unconventional PNW snowpack. 

The skin track up Big Trees was a little wonky, but that's life in the Valley, I guess. But the skiing was great.

I got some localized cracking as I re-established the skin track up to Pineapple Pass.

Weather

Mostly cloudy all day with the slightest flurry. Winds were generally light up on the ridge.

Snowpack

The upper snowpack continues to be generally weak, comprised of low-density snow, facets over a crust, and interspersed weak grains such as near-surface facets or surface hoar.

I did not find the 2/13 at the top of Draft Dodger Ridge today (NW 4916'). However, facets were found above the 2/7 crust. A PST on this layer resulted in a slab fracture 39/100. It did not propagate the fracture to the end of the block upon breaking vertically.

The 2/7 was down 38cm. ECTX

Avalanche

A handful of small, dry loose slides were observed coming out of steep, rocky terrain.
