Sudden Collapse followed by a 10cm creep occurred at 2,140m on the top of the little pyramid of lookers right when going to Perley Rock. It had a 10m by 20m surface area, and its depth of fracture is uncertain but considered to be on the Dec 22 layer. It was on a 35 degree slope, rocky & shallow at the top but deeper than 120cm at the start of the propagation. It occurred at 13:30 pm. The plan was for me to cross the slope, but that Sudden Collapse / Settlement occurred when I took one step forward. Assess data all day prior to that moment. No signs of instability were observed from hand shear tests done on the middle section of the slope or the top (1m away from the propagation).
