An Arizona Republican Congressman has condemned the National Park Service for adding the Oak Flat campground to the National Registry of Historic Places.

U.S. Rep. Paul Gosar called the campgrounds a "bogus" historic site that's meant to sabotage a mining company's efforts to reach a 1.7 billion-ton copper ore deposit that sits deep underneath the area.

Plans are in the works to develop the largest copper mine in North America on Arizona’s Tonto National Forest. The proposed site for the nearly 3,000-acre mine is Oak Flat near the town of Superior. It’s an ancestral home for several clans of the San Carlos Apache Tribe, some of whom are protesting the development. They believe the Oak Flat mine is another example of the conflict between the protection of sacred sites and economic development.

As Arizona Public Radio’s Ryan Heinsius reports, recent federal legislation cleared the way for the Oak Flat area to become part of North America’s largest copper mine.
