3 to 6 inches of new snow fell early Friday morning. On sunny SW slopes the new snow appeared to be bonding well to the existing snowpack.

Red Flags Comments
I skied up from the meadow at the end of the Gold Basin Road into the trees and found minor collapsing and cracking in several spots. As I got higher up, the angle steepened and the collapsing was more widespread.

Problem #1 Comments
I dug a pit near the bottom of Julie's where the run cuts right into the trees. Slope angle was 26*. Snow depth was around 45cm to 50cm. There were some weak layers mid pack, and the basal facets were alive and well, unfortunately. I did a CT with failure at the ground facets at CT25. I ventured out onto the slope about 15 feet from the pit and experienced a pretty widespread collapse.

Wind Drifted Snow
Trend
Same
Problem #2 Comments
I know there is a wind slab at higher elevations but did not encounter it because I was at lower elevations that are wind sheltered and below treeline.
