Comments

Had one more go at finding dry, soft snow in the very back bowl of White Pine behind the lake, and was not successful, like I said before all the high N facing terrain is a mixed bag of wind crust, sastrugi, and boilerplate with not much softening during the time we were out. E facing was really heating up today and shinning in the sun by afternoon. Wet activity was noted off the rocks on E facing with point releases taking the snow down to the slick underlying surface below. Some periods of rock fall and cascading wet slides were also noted coming out of the cliffs in the back of White Pine. With a shallow refreeze last night and intense solar radiation today E,S and W went off rapidly in the terrain covered. Made a point of staying out from under large overhanging cornices because I think there going to start dropping naturally as the heat already has them sagging. Same thing with rock fall, things are starting to thaw out for real this time and with continued heat and shallow or non existent refreezes things have the tendency to come unglued. Seems right now the main safety concerns are cornice falls, slide for life conditions and maybe wet slabs if this weather continues.

Photos: rock and ice fall coming off the cliffs in the back of White Pine around noon, new wet activity on E facing, strastrugi on the high north, wet debris in the S facing slide paths across the street.
