Signs of Unstable Snow

Observations

Went up to the top of Gunsight Ridge via Pocket Creek. Saw signs of yesterdays sun/warming mainly below 5000ft. In open exposed areas a thin sun crust had developed. Surface hoar was observed above 5000ft on both E and W aspects. Some areas near the top were wind scoured down to crust.

The first pit I dug was on a W aspect at 5600'. The top 20cm of snow went on CT03, another 30cm down failed on CT12.

The second pit was dug at 5700ft on a E aspect. This pit was dug in an area that was clearly wind loaded. Did an ECT with the first failure on the 10th compression, no propagation. another failure occurred below last weeks crust on ECT14. I then did a shovel tilt test and got results before I was able to move the column much. Pictures attached.
