Airborne electromagnetic and magnetotelluric geophysical surveys were conducted from 2018 to 2019 in Arrastra Gulch along the southern margins of the San Juan and Silverton calderas. This scene provides 3-D data integration combining electromagnetic data, geologic and historical mine mapping, and high-resolution drone imagery.

A Shallow to Deep View Inside the Hydrothermally Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations
The Silverton caldera complex in southwest Colorado hosts base and precious metals that have been mined since the late 1800s. Extensive mine workings, excellent bedrock exposures, and deeply incised drainages make this area a natural laboratory ideally suited for furthering our understanding of the mineral systems in a volcanic environment. In addition, state-of-the-art geophysical data processing... - Data
