Date of Observation: 11/13/2022
Name: Zach Guy
Zone: Southeast Mountains
Route Description: Working on a weather station on Carbonate Hill, descended Timbered Hill to Death Pass, traveling mostly on south to west aspects.
Observed avalanche activity: Yes
Avalanches: A small natural windslab on Carbonate from last storm. D1.
Weather: Light winds, clouds streaming in from the south. Ridgetop temp in the 20’s.
Snowpack: Fairly continuous coverage across all aspects at higher elevations, with the deepest/most continuous coverage on north to east facing terrain. Mid to low elevation southerlies are the only bare slopes at the moment. A couple of inches of recent snow was redistributed by winds above treeline and is now faceting over a variety of wind hardened surfaces. Near surface facets are more developed and more widespread as we descended in elevation; snowpack is generally faceted throughout below treeline, with one or two crusts on sunnier aspects. Snow depths are generally about 12″ to 18″ at 11,000′ and only a few inches at valley bottom.
