More detailed information about the snowpack: 

Warmer air temperatures & some intense solar radiation has been melting our deep snowpack, including huge looming cornices. Signs of wet loose snow are visible all around the BWRA in the form of roller-balls, cornice failures, & surface sluffs releasing. Early mornings are still below freezing in the BWRA creating icy surface snow, although below the crusts exists dry snow. Excersize caution while climbing or descending on this surface sun crust, it is surprisingly stout until after 1:PM. My pictures illustrate that cornices are being saturated by rapid melting & loosing strength. Take notice of icicles forming on cornices, especially when dripping, this indicates instability. The Marines are still training at Leavitt Lake, this area will periodically close until Tuesday. More asphalt is appearing in the prone wash-out zones on Hwy 108. Light cloud cover has been keeping the snow relatively firm & anticipation of snow this week will bring some uncertainty as to how the new snow will bond to this crust. Keep tuned for updates, thanks for playing in the BWRA!
