More detailed information about the snowpack: 

Toured up Reversed Peak, starting from June Mountain parking area. Blue skies and no wind all day. Great day in the Sierra.

Ski penetration 5-15cm during approach up south facing slopes. Snow here was low density powder (10-20cm depth) sitting on old rain crust. No cracking, whumping or instabilities on this aspect. No melting noted by 12:00pm.

We dug a quick, 1m deep pit at 9150ft, near the top of Reversed Peak couloir (NW aspect). Total snow depth=260cm. Snow here was heavily wind affected. Column test performed with no reaction (CTX). 25cm of dense (1 finger) snow sitting on 3cm rain crust. 1 finger snow beneath. 

Around 9000 ft snow in couloir was light, 15-20cm new snow sitting on rain crust. Ski cutting this layer resulted in only minor sluffing. Frequent small, loose sluffs while descending, not big enough to knock down a skiier. Enjoyable turns down to the road, though still bottoming out on rain crust for most of the descent. 

One small slide and one larger slide noted while touring back on the loop road. Both were on east facing aspects above Silver Lake Campground and appear to have happened today or possibly yesterday. (See photo). Starting elevation of the larger slide was approximately 8400 feet. Both slides looked to have started beneath rock bands. I would estimate the larger slide ran 300-400 feet, 40-50 feet wide.
