Comments
Went back to Tanners Gulch for two reasons, first the colder temperatures locked up the rock and ice fall I was experiencing on Friday, second was the wet slide threat was non existent and there wasn't enough new snow or wind yet to create a concern of dry avalanches coming down from the upper bowl but there was allot of spindrift avalanches coming off the granite walls but they just didn't have enough volume to be a major concern. The new snow seemed to bond fairly well to the not completely frozen bed surface, except on the steep sidewalls where it was constantly sluffing. That being said I wouldn't want to be in that confined walled in space if the snow amounts were higher or if the wind was drifting snow up high. Some larger spindrift avalanches told us it was time to leave.

I would be wary of any south, steep facing slopes that heat up tomorrow, there's a slick bed surface and 5 inches of snow can gain a lot of mass and energy when it gets going in confined spaces
