Geologic controls on groundwater flow, particularly in tectonically and topographically complex mountainous terrain, can be difficult to quantify without a detailed understanding of the regional subsurface geologic structure. This structure can influence the magnitude of groundwater flow through the mountain block, which in turn impacts groundwater composition and the flux of metals and nutrients to the near-surface ecosystem. In support of several ongoing studies in the upper East River and surrounding watersheds in central Colorado, regional-scale airborne electromagnetic, magnetic, and radiometric surveyswereconductedin late 2017. These data give a view of the geologic structure underlying the region that is unprecedented in both resolution and spatial coverage.
