The Great Basin is a geologic formation caused by collisions of tectonic plates millions of years ago. Encompassing almost all of Nevada and parts of adjoining states, the Great Basin has more distinct mountain ranges than th rest of North America.
In the Great Basin, water from the mountains does not flow to the sea; instead, it percolates into the ground, forms lakes or evaporates.
The small national park is located in East central Nevada, on the border with Utah. It is centered on the glacier-scoured Snake Range, dominated by its highest mountain, 13,063-foot Wheeler Peak.
The labyrinthine Lehman Caves are found at the foot of Wheeler Peak, penetrating a quarter-mile into solid rock.
