Grand Turk is a 13,167-foot-elevation (4,013-meter) mountain summit in San Juan County, Colorado, United States.

It is located three miles (4.8 km) southwest of the community of Silverton, on land managed by San Juan National Forest.

Topographic relief is significant as the summit rises nearly 4,000 feet (1,200 meters) above the river in 1.75 mile (2.82 km).

[3] The mountain's toponym has been officially adopted by the United States Board on Geographic Names,[2] and has been recorded in publications since at least 1901.

[6] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring.
