The Gore Range (elevation approximately 12,000 ft) is a mountain range in the Rocky Mountains of north central Colorado in the United States. The range runs for approximately 60 miles (100 km) northwest-to-southeast, through western Grand and Summit counties, and eastern Routt and Eagle counties. They form the southern extension of the Park Range, extending southward from Rabbit Ears Pass (U.S. Highway 40) to the Eagle River near Vail.
