Comments
There is around 12' of snow on the ground around Tony Grove Lake. Huge and dangerous overhanging cornices are found on the upper elevation ridges.
There has been quite a bit of settlement of the new snow in recent days...Settlement helps to stabalize the snow.
The low elevation snow is still layered, and there are some loose (weak) layers....
