In May 2001, the Bush administration upheld Anschutz's right to drill an exploratory oil well at Weatherman Draw in south-central Montana where Native American tribes wanted to preserve sacred rock drawings. Environmental groups, preservationists, and ten Native American tribes appealed the decision without success. In April 2002, the Anschutz Exploration Corporation gave up its plans to drill for oil in the area. They donated its leases for oil and gas rights to the National Trust for Historic Preservation, which has pledged to let the leases expire, and the Bureau of Land Management said it had no plans to permit further leases there and would consider formal withdrawal of the 4,268-acre (17 km²) site from mineral leasing in its 2004 management plan. In recognition of its preservation efforts, The National Trust for Historic Preservation presented its President's Award to the Anschutz Exploration Corporation.
