Quick loop on the sleds around Black Canyon. 50 cm (~20 inches) of snow at 8000'. Good layer of surface hoar on top, and the upper part of the snowpack is starting to facet. Non-issue for now with snow coming this week that could double the snowpack. 

South facing slopes have some damp snow.

Early season conditions. At 8000' just below the Sacajawea trail bowl, there is about 9" of snow. In the trail bowl, winds moved that snow around and there is nice firm, supportable (ie - not hitting rocks) snow. 
 

Warm weather really settled the snow and it became damp today on many sun exposed slopes. It stayed dry and cold on high north. 
 

Overall, the things seem quite stable, even though there may be a wind slab or two that could still avalanche.

Notes

From obs 11/6/24: "Saw debris from several small natural avalanches below the ridge on an east aspect south of saddle peak while driving up to bridger. Most looked like point releases but there was one that might have been a small slab. Unsure because the light wasn't right to tell if there was a crown.

We stayed low but found a pretty uniform snowpack other than a couple of spots with sun crusts.

There was also tons of snow blowing over the ridge when we left around 3pm."
