    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.
