More detailed information about the avalanche: 

Updated to reflect change from partial burial to full burial status per additional info received from party involved:

Skier triggered deep slab avalanche that resulted in a full burial with minor injury and the involvement of an automobile in avalanche debris on NV Hwy 431 below. Crown depth ranged from 2 to 6 feet and wrapped across interrupting terrain features. Bed surface was Dec 15 rain crust. Failure weak layer was F hard near crust facets (old snow from pre storm). Overlying slab consisted of entire amount of recent storm snow plus up to 8 in ches (20 cm) of old snow above the rain crust. Base of slab was 1 F+ hard. Slope angle measured at the site where video was taken was 36 degrees. Other portions of the slope appeared steeper but were not measured.
