Images showing the locations of 77 leases for natural gas and oil drilling, on public land in Utah, that were auctioned off to the oil and gas industry by the Bureau of Land Management in December 2008. These leases were suspended by the federal government in February 2009 pending further review by the Department of the Interior, after receiving over 1,600 complaints from environmental groups, the Outdoor Industry Association, sportsmen organizations, and a collection of river runners, guides, and outfitters.

Several of the leases are adjacent to, or within a few miles of, Dinosaur National Monument, Canyonlands National Park, and Arches National Park.

We've included a few images showing current drilling operations in nearby parts of the Uinta Basin, to give you an idea of how severely the suspended areas could be altered if Interior decides to go ahead and approve the leases.
