Collection Overview: The EarthScope Alaska Denali-Totschunda Lidar project acquired high-resolution lidar topography data along the Denali-Totschunda fault system as part of the EarthScope Facility project. EarthScope is funded by NSF and conducted in partnership with the USGS and NASA. GeoEarthScope is a component of EarthScope that includes the acquisition of aerial and satellite imagery and geochronology. GeoEarthScope is managed at UNAVCO.Please use the following language to acknowledge EarthScope Lidar:This material is based on services provided to the Plate Boundary Observatory by NCALM (https://ncalm.cive.uh.edu/). PBO is operated by UNAVCO for EarthScope (http://www.earthscope.org) and supported by the National Science Foundation (No. EAR-0350028 and EAR-0732947).Publications associated with this dataset can be found at NCALM's Data Tracking Center
