The Inyo Mountains are a short mountain range east of the Sierra Nevada in eastern California in the United States. The range separates the Owens Valley to the west from Saline Valley to the east, extending for approximately 70 miles (110 km) south-southeast from the southern end of the White Mountains, from which they are separated by Westgard Pass, to the east of Owens Lake.
Geologically, the mountains are a fault block range in the Basin and Range Province, at the western end of the Great Basin. They are considered to be among the most important and best-known Late Proterozoic to Cambrian sections in the United States.
