Utah Avalanche Center

Appeared to be representative of area -

Pretty good stability. ~80 cm of new snow on mid February crusts

Dug in three places. This is the only one that produced an ECTP. Others have similar layers but must have been stronger. We dug at 9000ft on ENE and at 8800 ft on NNW. Neither spot even produced ECTN's under the dust layers. However, we spotted one natural avalanche and know of another in the area. The one we spotted seemed to be a similar depth as the weak layer in this pit.

deeper and more stable than expected

Cold

Surface hoar won't break in stability tests. It's hard to get the ECT column to shear at that layer with my hand. Did a PST on the surface hoar and it propagated to the end after a 35 cm cut. Not really sure what that all means. On Feb 2nd, we shoveled extra snow on top of the snowpack and let it sinter. We returned and the surface hoar was unreactive in stability tests. Given the recent load (1.2" swe on Feb 18&19) and ECTN scores, I'd say it's no longer a concern.

No wind loading at this location but significant transport occurring 400' higher at tree line and above. Dust layer from strong winds prior to most recent storm at 80cm.
