More detailed information about the snowpack: 

Cold dry powder was precipitating at a S5 (+2"/hr) rate. HST was 10" for our study location at Sonora Snotel site @ 8770'. Measurements elsewhere & Leavitt Lakes Snotel found almost 16" near treeline. At 25-30cm deep within the new snow a layer of large (3-4mm) Graupel mixed with Rimed Particles was found. This layer of concern has a small buffer of rounds above a pencil hard Melt-Freeze Crust. In compression stability tests no reults were found. Temperatures within the snopack became isothermal, or near freezing, below the mfc and moisture content became greater. Full height of snowpack in pit location above Deadman Creek 165cm (65").
