Comments
We dug a pit near the start zone of Lane's Leap (NE, 9600ft). I would have uploaded the snow profile photo but it would only upload sideways, and it's the same snow profile we've been staring at for days anyway: 18" of cohesive new snow on top of a variety of alternating facets and crusts.
