Observations from Carson Passs

Little surface indications of instability, but digging a pit reveals persistent weak layer of buried near surface facets. Deep tap test results indicate this layer is still a concern. Facets easily identifiable and are down 125 cms at this location. Test slopes along the route to Frog lake at Carson Pass showed virtually no slab properties (no cracking). A few areas had recent sun crust formation from earlier today. 

Photo 1: 270 cm total snow height at this location. Buried facets down 125 cms. 

Photo 2: Deep tap test. DTM13 on buried NSFs.

Photo 3: Large crack behind where a cornice had partially broken away previously. This was covered by a thin snow bridge.
