The first three show fractures and a slide caused by two gentlemen that decided to drop into unopened terrain along the road. They did not actually trigger a slide until they were almost to the road. The fracturing that occurred up slope, however, was incredible. This is and easterly facing slope and the fractures are 2.5-3' deep, going down to the faceted layer. Hand pits failed on the back cut. It is amazing that the entire slope did not go!
