Location:   Turnagain   -   Girdwood Valley and Turnagain Pass

Below are a few photos of the old snow that has been sitting around and faceting
under the past weeks of high pressure...

The snow has lost so much cohesion and become so weak that we have seen
facet-lanches (or facet sluffs). see photos

Some Details:
General snowpack depth: 0-16"
General snowpack hardness: fist hard
General surface conditions: surface hoar .5cm to 20cm (big...)
