Here is an observation from New Years Day from Dry Canyon, DB. I saw the remains of an ~ 500 ft wide slide that spanned most of the west side of upper DB bowl as I skinned and skied a nearby sub-ridge. I was at probably 1/2 mile away so all of the following are rough estimates. Crown 2-3 ft. Starting elevation about 8800. NW aspect. Ran at least 200' vertical but could be longer as I couldn't see the runout from my vantage point. Date/Time unknown. Trigger--likely natural as I didn't see any other tracks nearby. Also of interest, bed surface was completely white -- didn't see any grass, rocks, brush, or cone flowers sticking up which I would take to mean that the slide broke half way down through the snow pack (rather than on the bed facets). Since timing is unknown, alternatively, the slide could have ran during the last storm cycle and new accumulation covered the bed. The slide looked fresh/recent though. Based on the weather (see below), I think the slide was recent and caused by wind loading.

Weather today was calm in the canyon but extremely windy on the Little Baldy ridge. Above DB and Exit, wind was out of the SE. Lots of snow transport and loading N/NW aspects such as the face of DB that slid. Near and on the ridge, there were extremely variable conditions that ranged from beautiful, soft settled powder, to complete scour, to soft wind slabs 1" thick that broke in cookie crumble pieces with no energy while skinning, to hard wind slabs up to 5" thick that broke in chair to desk sized pieces with a bit of energy. In places, the skin track was completely filled back in with a hard slab an hour or so later on the second run.

(T. Weed) : I visited the site on 1-2-2016 and found that although fairly recent, the avalanche was at least several days old. There was a few inches of well deteriorated and previously drifted snow on the bed surface of the avalanche.
