Dense slabs that were formed last week lie upon buried surface hoar. On steep north facing aspects, above an elevation of 9,000 feet, weak faceted snow persist at the base of the snowpack. Surface slabs with depths to three feet could be triggered by the weight of a person and have potential to step down to the ground in isolated areas. Thoughtful decision making is key as most terrain will show stability however areas of instability persist, particularly in on very steep slopes.
