Snowpit Observations
More detailed information about the snowpack: 

Dug a quick pit above Aspendell Meadow (near approach to Bishop Bowl). ~8600', North Facing, 25 degree slope. CT13 Q3 at 18cm. Failure at density change from 1F wet snow, to P below.

Snow soggy with boot pen 30+cm. Runnels evident on slopes up to 9000'.

Numerous point releases and several wet slab avalanches (see photos) 

The avalanches were fairly new. I would think within the last 12 hours would be a decent estimate.

I put the aspect in the title for the pics, but not sure they came through.

The slide above the houses was NW, the others were NE and SE.

Saw slides on all aspects except S.

All were between 8500 and 9500. I did not see any slides in the higher elevation terrain of Bishop Bowl, Table Mtn, Jawbone Canyon etc.

Using CalTopo it looks like the slides occurred on slopes around 33 to 38 degrees.

The largest slide was D3, but most were D1 or D2. Relative to path I would say as high as R4, mostly R2 to R3.
