Abandoned Mines Program

Royal Gorge Abandoned Mines Program

The RGFO has had an active Abandoned Mined Land Program ongoing since 1993.  The program began as an inventory program. 

The BLM has developed a mechanism for mapping abandoned mines that is based on sites and features.  Basically a site is a geographic location that may include a number of features such as roads, buildings, shafts, adits, etc.   When work is contemplated, one or more sites or features may be combined into a project.  Starting in 1998 a number of projects were implemented focusing on both environmental and safety issues.  These projects are discussed in those two sections.

The RGFO has developed a close working relationship with the Colorado Division of Reclamation, Mining and Safety (CDRMS) regarding abandoned mines work.  The CDRMS has had an ongoing program for about 25 years and have the expertise on hand to develop abandoned mine projects.  Additionally the BLM and the CDRMS have developed cost sharing approaches to completing projects.
