Site Location:
Alma, CO 80420

Status Update
5/21/24 - EPA anticipates mobilizing to the site after the fourth of July based on snow levels and Buckskin Creek’s water flow. This year’s work will be focused on erosion controls and removing waste rock and mine tailings from the creek and surrounding areas. This work will reduce the overall metals entering the creek and flowing downhill to the town of Alma. In 2023, EPA capped the ponds on forest service land with USFS oversight.


The Buckskin Joe mine site is located approximately 1.8 miles west of the town of Alma, in Park County, Colorado, off of County Road 8. Precious metal mining was initiated at the Buckskin Joe mine site in 1859 and continued until approximately 1957 with various ownership and areas of mining focus. Currently, two mine adits are observed at the site (upper and lower), as well as a large mine dump. The lower adit is observed to be partially blocked by collapse material while also releasing mine influenced water (MIW). This adit is located adjacent to Buckskin gulch, and up-gradient of the potable water intake for the town of Alma, Colorado. Little is known about the partially blocked adit, while the potential exists for an uncontrolled mine pool release from the adit. To investigate the lower Buckskin Joe adit, coring activities designed to determine MIW loading behind the adit collapse will be conducted starting on August 12, 2020.
