Big Indian Mountain is a high mountain pass at an elevation of 2.987m (9,799ft) above the sea level, located in Mineral County, in the U.S. state of Nevada. It's one of the highest roads of Nevada.
Set high in the Wassuk Range of Western Nevada, the road to the summit is totally unpaved. It’s called Cory Canyon Road. The trail is narrow with few places for passing so meeting someone can be a challenge. In order to drive this road up, you need a 4x4 vehicle with high clearance.
This road is usually impassable from late October through late June or early July (depending on snow). The road to the summit is very steep, hitting a 16.5% of maximum gradient through some of the ramps. Starting at the paved State Road 359, the ascent is 20.11km (12.5 miles) long. Over this distance the elevation gain is 1.502 meters. The average gradient is 7.46%.
