Electromagnetic induction data collected along the Lake Fork Creek corridor and wetland area in Leadville, Colorado, 2023 and 2024
Multiple sources of mine drainage including discharge from the abandoned Dinero mine tunnel and two gulches flow into a wetland, known herein as the Dinero wetland along the Lake Fork Creek corridor. The Dinero wetland is approximately 20 acres in extent. The Dinero wetland is being considered as a location for passive treatment of the mine drainage flowing through it. As such, study objectives are to understand: (1) variations in pH, specific conductance, and temperature in surface water in the wetland; (2) metal loading into and out of the wetland; (3) the configuration of surface drainage features; (4) the configuration of subsurface conductive features; and (4) depth to bedrock in the wetland. These data will be used to help understand whether the wetland is currently and naturally treating the mine drainage flowing through it and will help pinpoint locations needing additional investigations to help inform potential passive treatment scenarios.
Near-surface frequency domain electromagnetic induction (FDEM) data were collected in an alpine wetland downgradient of the Dinero Tunnel mine portal near Leadville Colorado on August 17, 2023 and July 16-17, 2024. FDEM data were collected on foot along an approximate grid pattern with a Geophex GEM-2 Instrument. An EMLID Reach RS2+ base station was established, while a rover antenna receiving real-time kinematic (RTK) corrections was used to transmit GPS positions to the GEM-2 logger.
This child item includes the raw and processed data, as well as inverted electrical resistivity models from these surveys.
