Jenny Bowl

The top few inches of snow was moist in most areas I travelled. The only exception was ridgetop west and north aspects, which were still dry around noon. Ridgetop winds were light to moderate from the southwest. As soon as I dropped out of the wind, the temperature felt hot. I even measured 44 F in the shade at one point!

I found the January 4th facet layer buried 18 inches deep in a pit on a southeast aspect. I got no test results on this layer. I did get a few hard test results within old wind slabs in the top 8 inches of snow. See the snowpack summary below for details. I also dug on an east aspect a bit lower, and got no test results.

The top 2-4 inches of snow was moist on east, southeast, south, and southwest aspects. Westerly and northerly aspects remained dry above 7500 feet. I was unable to observe these aspects at lower elevations.

I found the January 4th near-surface facets buried 46 cm (18 inches) on a southeast aspect at 7580 feet. They looked to be rounding, and I got no test results on them.

This pit was just below ridgetop and previously wind-loaded. I got non-propagating extended column test results and hard compression test results within old wind slab layers. ECTN 18 dn 15. ECTN 30 dn 21. CT21 dn 12 (RP). CT28 dn 21 (RP).

I also dug on an east aspect at 7620 feet (see attached picture and profile). I found what I believe was the January 4th interface 38 cm (15 inches) down, but the grains were not obviously faceted. The layer was 3 cm (1 inch) thick and only slightly softer than the snow above it (4f- versus 4f). I got no test results in this pit.

On a south aspect at 7590 feet, I found crusts buried 25, 35, and 70 cm (10, 14, 28 inches).
