Rain Crust Lurking

Dug a pit an conducted isolated colum and extended colum tests Isolated colum shoved failures at: 7- down 7cm on 1.4mm SH 18- down 40cm on rain crust 22- down 25cm on 2.5mm SH Our extended colum test however was the most troubling find of the day. 14- down 40 on rain crust The failure propagated colum wide and the block slid off. Other walking around the pit by my partner produced these same results with the upslope sliding into the pit on this layer.
