Snowpit Observations
More detailed information about the snowpack: 

Several of the chutes on the northeast side of Table Mountain between Four Jeffries Campgrond and Bishop Creek Lodge slid at some point during the recent storm cycle, leaving debris piles visible.  Start zones were hard to determine, probably because they were blown in with wind deposition.  Sizes ranged D1-2, R2-3. Down-canyon (southerly) winds deposited snow on the north sides of ridges dropping down the face of Table Mountain, but rock and brush had snow accumulation on south sides, indicating north winds.

We toured from the winter road closure past Bishop Creek Lodge up the road on the east side of the canyon and into the Habbeggers Glades.  Patchy hollow wind board and numerous noisy collapses on the tour up.  Snow pit in the first glade was basically a 58 cm storm layer from the recent storms on top of 49 cm of basal facets (see attached profile), with ECTP6 at the interface between the storm layer and the facets.

Other members of the party skied the first glade without any problems, but Darla and I didn't (we were in the snow pit). Skiing down the moraine was bad - thin variable windboard and brush hummocks.

Storm layer in the pit was 22.8".  The South Lake snow pillow reports a 31" storm layer.
