Hydrologic and Geochemical Data and Models Supporting Integrated Evaluation of the Captain Jack Superfund Site, Boulder County, Colorado The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead within the workings to preclude drainage out of the mine. To understand the processes occurring during water impoundment within the mine workings, the U.S. Geological Survey (USGS), in cooperation with EPA, completed water-quality sampling and analysis during 2020 as water was impounded within the mine workings. The USGS sampling...

Distance of about 12 miles from the summit. Boulder and Larimer Counties, Colorado. 1973. Long's Peak, a view from Estes Park on the northwest. Distance of about 12 miles from the summit. The park is about 4 by 6 miles in diameter, lying inside the foot-hill range and close under the main range. Long's Peak, as seen from the plains, is the most prominent in the front range, rising sharply high above the surrounding peaks. Its elevation is 14,271 feet and about 6,300 feet above the park. Boulder and Larimer counties, Colorado. 1973. (Photo same as jwh01285).
