Bacon Rind Crack

As we skinned up the slope we got a large "whumph" and crack that propagated about 75 feet uphill.  We dug into the crack and saw it was collapsing on a 1.5cm thick layer of well developed, feathery, surface hoar.  This is Bulls-eye information that the snowpack is unstable.  We made a video of the snowpit too: http://www.youtube.com/watch?v=NDthVJsSFjE  Photo: GNFAC
