We were skiing low angle NE ridge of White Pine knob and saw that CYP had slid so we went over to check it out. Ascending to the east and looking across we saw the adjacent slope (to the west) had also slid. There were tracks on the ridge from the previous yurt guests and we don't know if they were possibly remotely triggered or were natural. We saw them on the evening of February 17th and they clearly had been snowed on since sliding.
