Collection Overview: This dataset was collected as an NCALM Seed grant for PI Kendra Johnson of Colorado School of Mines. The survey area consists of a corridor polygon located 20 km northwest of West Yellowstone, MT.  The dataset was collected to study degradation of the 1959 Hebgen Lake rupture and the application of diffusion coefficients to undated scarps in the north Rocky Mountains and Mongolia.Publications associated with this dataset can be found at NCALM's Data Tracking Center
