    Collection Overview: NCALM logo

    This lidar dataset was collected as part of an NCALM Seed grant for Sophie Rothman at the University of Nevada, Reno. This study used airborne lidar to assess how self-generation and retreat of bedrock steps and waterfalls can alter river profiles. The study area is along selected rivers within the Sierra Nevada mountains in California and covers approximately 73 km2.
