Glen Canyon National Recreation Area: Geologic Resources Inventory report
Graham JP. 2016. Glen Canyon National Recreation Area: Geologic Resources Inventory report. Natural Resource Report. NPS/NRSS/GRD/NRR—2016/1264. National Park Service. Fort Collins, Colorado
The Geologic Resources Inventory (GRI) is one of 12 inventories funded by the National Park Service (NPS) Inventory and Monitoring Program. The Geologic Resources Division of the NPS Natural Resource Stewardship and Science Directorate administers the GRI. This report synthesizes discussions from a scoping meeting for Glen Canyon National Recreation Area (Arizona and Utah) on 23–25 September 1999 and a follow-up conference call on 5 March 2015, which were held by the Geologic Resources Division to determine geologic resources, the status of geologic mapping, and geologic resource management issues and needs. It is a companion document to previously completed GRI GIS data. Glen Canyon National Recreation Area encompasses geologic features, landforms, and landscapes that are part of America’s geologic heritage. Preservation of these features enriches a full range of values that contributed, and continue to contribute, to our country’s history and culture. Glen Canyon National Recreation Area was established in 1972 to preserve the area’s scenic, scientific, and historic features and to provide public use and enjoyment of Lake Powell. The recreation area’s 506,000 ha (1.25 million ac) not only include Lake Powell but also sections of the Colorado and San Juan rivers. About 51% of Glen Canyon National Recreation Area consists of proposed and potential wilderness, considered to be a fundamental resource in the recreation area’s Foundation Document. Located on the Colorado Plateau, a physiographic province that spans roughly 34 million ha (84 million ac), Glen Canyon National Recreation Area shares a border with other national park system units including Grand Canyon National Park, Capitol Reef National Park, Canyonlands National Park, and Rainbow Bridge National Monument. In addition, the recreation area shares 800 km (500 mi) of its southern boundary with the Navajo Nation, and it adjoins public lands administered by the Bureau of Land Management, including the Grand Staircase-Escalante and Vermilion Cliffs National Monuments and the Paria Canyon-Vermilion cliffs Wilderness.
