Hydrologic reconnaissance to identify areas of emergent groundwater, Mineral Creek, near Silverton, Colorado, June 2020
Results of a field survey of emergent groundwater in this area to help characterize subsurface rock properties important for understanding surface water and groundwater quality issues, and to improve knowledge of shallow to deep faults and vein-structures that were conduits for hydrothermal fluids that formed mineral deposits. Data are provided in KML, CSV, and shapefile formats. Images of the locations are provided in JPEG format. |
