Grand Canyon, Ariz. -- Beginning in early November 2010, the National Park Service will conduct several projects at abandoned mines throughout Grand Canyon National Park to make them safer for park visitors. Active mining occurred in
Bat-accessible gates will be installed at four mine sites. Bat gates preserve critical habitat for bats in old mine sites while preventing people from entering hazardous areas. At the Grandview Mine, where bat gates were installed in the main mining area in 2009, two shallowadits and a prospecting pit will be permanently backfilled.
Physical Science Program Manager Deanna Greco said, “The eight mine features scheduled for closure all present significant hazards to visitors and this project is enabling the park to address this critical safety issue. For example, the Tanner-McCormick Mine along the Beamer Trail has pockets of poor air quality with low oxygen levels.”
Grand Canyon National Park Superintendent Steve Martin adds, “Work on this project would not have been possible without funding from the American Recovery and Reinvestment Act. This project makes old mining sites safer for human visitation, while also providing habitat for sensitive species of wildlife and preserving cultural resources.”
An Environmental Assessment (EA) was prepared under the National Environmental Policy Act for closures of Abandoned Mine Lands at Coronado National Memorial,
