The geology of Nevada began to form in the Proterozoic at the western margin of North America. Terranes accreted to the continent as a marine environment dominated the area through the Paleozoic and Mesozoic periods. Intense volcanism, the horst and graben landscape of the Basin and Range Province originating from the Farallon Plate, and both glaciers and valley lakes have played important roles in the region throughout the past 66 million years.
The Great Basin National Heritage Area is the epitome of remote destinations with the Great Basin National Park, hundreds of miles of ATV trails, and numerous natural attractions. Explore the wide open spaces, travel uncrowded trails, and experience some of the darkest night skies in the country.
Burrowed in the Toquima Range in the Humboldt-Toiyabe National Forest, Toquima Cave holds massive cultural importance to Native Americans. This sacred site was utilized by the Western Shoshone tribes as a temporary dwelling between 3,000 and 1,500 years ago.
A large number of pictographs adorn the north and south walls of the cave. As one of many pictograph sites in Nevada, Toquima Cave and the surrounding 40 acres were added to the National Register of Historic Places in 2002.
