Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Anna Marshall at Colorado State University. This dataset was collected to help understand sources and functions of spatial heterogeneity in determining channel evolution of large mountain rivers.  Lidar surveys were conducted over the Swan and Middle Fork Flathead rivers in Montana.
