Avalanche: Turnagain

Location: Johnson Pass

Route & General Observations

Rode from Moose Pass to Johnson Pass to get eyes on this area that we have not been to yet this season. A high degree of wind effect was seen everywhere. Lots of scoured ridges, wind loaded gullies, and some old crowns of wind slabs that released during the strong northerly wind event (Jan 15-17). Soft settled snow was found in valley bottoms and sheltered zones.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Sunny skies and calm winds.
Temps were single digits F in the Trail River drainage and in the teens in Johnson Pass itself.

Snow surface

Soft settled powder that is becoming faceted in valley bottoms.
Variable wind affected conditions in the higher terrain; that did not look too appealing for skiing or riding .


We dug a quick pit at 2,000', which was out high point. Total snowpack depth was 3-4 feet only. This was a bit of a wind scoured shoulder. There was no slab, just a series of older faceted snow with some crusts. No red flags seen and no signs of recent avalanches, save for a few old wind slabs in very steep wind loaded terrain (photos below).
