This Unoccupied Aerial Vehicle (UAV) survey was flown to provide geology field camp students with a high-resolution orthomosaic, Digital Elevation Model (DEM), and Point Cloud of the entrance to the Grape Creek mapping area. The area shows monocline of Cretaceous beds dipping to the Southeast in the Frontal Range.
