More detailed information about the snowpack: 

Toured up Bishop Creek toward South Lake.  Between Parchers Camp and South Lake, left the road to head toward the ridge above and east of South Lake (see map).  Many avalanches in the chutes off the east face of Table Mountain and west face of Coyote Ridge from the 3/21-3/22 storm, most appeared to be in the D1-D2 range, with a couple of D2+.  None ran all the way to the canyon bottom.  Most crowns were obscured by storm snow or wind deposition subsequent to the slides.  One deep crown was visible in a chute off Table Mountain just north of the Tyee Bridge.  South winds running down the canyon cross loaded east-west oriented ridge features, and resulting in at least two D1 natural releases (possible cornice triggers).   

At the Tyee Bridge (~9,000 ft), snow depth ranged 60-81 cm where it wasn't too wind affected (e.g., bottom of summer trail).

Dug a snow pit at ~10,300 in the north facing bowl between South Lake and Parchers (see map and attached profile).  Total depth = 160cm, CTH RP @ 129 cm, and CTH RP @ 101cm.  Both occurred on indistinct hardness changes within the 3/21- 3/22 storm layer. Well developed 3 mm facets at the base (in talus). Across the snow pit, the thickness of the basal facets ranged from 0 to 30 cm.
