Snowpack Observations


A trip up into Gray Rock Lakes basin saw a snowpack in transition. Dry snow was holding in north facing, cold, dark areas -- not worth seeking out for skiers. Anything facing direct sun was soft and moist, though other aspects, exposed but not in the path of the beating of the sun, were still firm but breakable -- a mixed bag of conditions. Borderline spring skiing conditions could be found. Steep slopes let loose roller balls,  pin wheels, and point releases. North facing ridges were lined with overhanging cornices, but none had begun to break in the warming temperatures. The main concern tomorrow will be breaking cornices that are exposed to the sun and subject to above freezing conditions.

Anyone heading up South Fork Road should be prepared for rough conditions. It is deeply rutted out all the way.
