Great Basin National Park is a United States National Park located in White Pine County in east-central Nevada, near the Utah border. The park was established in 1986. It is most commonly accessed by way of Nevada State Route 488, which is connected to U.S. Routes 6 and 50 by Nevada State Route 487 via the small town of Baker, the closest settlement to the park.
The park derives its name from the Great Basin, the dry and mountainous region between the Sierra Nevada and the Wasatch Mountains. Topographically, this area is known as the Basin and Range Province. The park is located approximately 290 miles north of Las Vegas and protects 77,180 acres.
The park is notable for its groves of ancient bristlecone pines, the oldest known non-clonal organisms; and for the Lehman Caves at the base of 13,063-foot (3,982 m) Wheeler Peak. The peak is also home to Wheeler Peak Glacier, which despite claims is much further north than Mount Everest and the Himalaya glaciers, so is not the southernmost glacier in the northern hemisphere.
