December 12

Grizzly Gulch, Silver, Days, Cardiff, Reynolds Flat

Elevations, slope angles and aspects

7400-10k+, angles over 35°, all aspects

Snow conditions

Dense recent snow at all elevations. An inch of fresh eliminated the fluff at upper elevations with, a rain rime event crusting elevations below about 9300'.

rain-rime

Off aspects at all but the highest elevations and south facing warmed enough to initiate wet activity(mostly rollers). Mid and lower elevations cooled enough to crust late in the day.

There was a bit of drifting and scouring at all elevations. Drifts were not sensitive in areas traveled through

Weather

Foggy and humid in the a.m. Sunny by mid day. Temperatures were mild and winds were light.

Avalanche activity

Recent roof slide along the summer road at the base of Grizzly Gulch.

Glide was observed in the Diving Board area of Broads.

Rollers off the rocks are also seen at the bottom of the photo in Mill B south, ese facing.

Evaluation

Wet activity would continue to be of concern. There may also still be some active drifts at upper elevations. Potential for further glide exists.
