More detailed information about the snowpack: 

Breakable crust existed on all aspects up to at least 9300 ft. in the Carson Pass area. From a distance the sun glinting off of the snowpack at higher elevations made it appear that this crust likely extended into higher elevation terrain. Below this breakable crust, some softer snow existed with a mix of rain crusts and old snow below the surface. On some true north aspects, snowpit data, handpits, and probing found that the loose weak layer of old facets still remained at a depth of 25 to 60cm below the surface depending on whether or not a slope had been previously wind loaded. One pit showed this layer to be moist and another showed it to be drier. Tests at both of these sites yielded unstable results on this layer (one point where the snowpit is from and another N apsect test slope near Frog Lake). On all other aspects including the SE, E, and NE aspects, finding this weak layer proved to be very difficult and tests on those aspects did not reveal any signs of instability. Observations showed a strengthening snowpack. 

Cornices still loomed above the E and NE aspects of Elephants Back (coordinates attached to this ob). Very little evidence of E wind scouring existed.
