Abandoned Mine Lands Program
There are many accessible old mining sites on lands administered by the Bureau of Land Management (BLM). These old abandoned sites may pose a physical and/or chemical/environmental hazard. Mine openings, such as shafts and adits, and unstable highwalls or old structures should be avoided. Old chemicals, such as very corrosive acids or unstable explosives may be found and should not be touched. The St. George Field Office in partnership with the State of Utah, Division of Oil, Gas, and Mining has been involved in identification and remediation of the hazards associated with old mines as part of its Abandoned Mine Lands (AML) Program. The Silver Reef and East Reef AML projects near Leeds in Washington County, Utah, identified approximately 113 hazards on BLM administered lands that were mitigated by sealing or gating.
