More detailed information about the avalanche: 

Thanks to Matthew Larsen, Inyo County SAR, for providing the details and photos.

Hiker was believed to have attempted to climb Mt Mallory and possible Mt. Irvine from his car parked in the Whitney Portal area. He was reported missing on Nov. 18 and Inyo SAR and other SAR teams located him on Nov. 21 2015 with a Recco detector provided by Mono County SAR. The victim was located 2 feet under the snow surface at the toe of the avalanche. The depth of debris at the toe was 5 feet. It is likely that he triggered the slide. 

The crowns of the avalanche are shown in the aerial photos. The photos were shared with colleagues at the Colorado Avalanche Information Center. Based on the location of the crown and crack propagation below rocks and downslope where a secondary avalanche occurred, the consensus opinion is that this is a presistent slab avalanche problem.
