Comments
This Natural slide likely occurred on the eve of March 7 just after frontal passage. It is at 10,000' in Primrose Cirque, E-SE aspect. I don't have much info on this except it is at least 300' wide and from a distance it appears to be deeper than the amount of storm snow that the Provo area received during this last storm. Storm total was about 12" with 1" of H2O at 7500'. Once it turned NW, it shut right down. With such a small new load, slides like this one and those that Cowboy reported are puzzling. Will try to get more info on what the culprit is soon.
Comments
These are shallower SS-N-D2-S slides that occurred around the same time as the one above. This is Cascade Cirque just NW of Sundance.
