It was a beautiful morning in the June Lake Backcountry with mostly clear skies, light winds, and cool temperatures. A trace of new snow on a supportable MF crust softened up the descent from the top of J7 as I made my way to the Hourglass. Looking across at the Negatives surface conditions appeared wind effected on the more northerly terrain with ribbons of smooth snow interrupted by wind drifts and small surface deformations. More solar facing terrain appeared to be back to the old snow surface. 

After climbing to the top of the negatives I traversed the ridge towards dream peak.  Along the ridge, I observed a few areas of recent Wind deposit. In the form of recent cornice deposit or isolated panels of wind slab, I found slabs to be 15-25cm thick, 4F+/F, and fairly sensitive. I did not observe any deposits of concerning size, but I imagine they could be out there.  Reactive panels were isolated to leeward catchment zones right on the ridgeline and were easily managed. 

Surface conditions were quite variable on my descent. I found some areas of soft turns in gully features with 4f snow ranging from 20-40 cm deep and in these areas I managed to initiate some loose dry sloughing that ran about 400’.  On more open slopes I found surface conditions to be more wind effected with less soft snow (10-20cm) and a grabby wind board underneath. Below 10,000’ or so on a solar aspect I found qazi corn snow. The surface melt was limited to the top 1cm or so but the turns were pleasant. All in all a mixed bag.
