Steamboat Rock, reaching an elevation of 6,074 ft (1,851 m) is a promontory located in the eastern Uinta Mountains, in Moffat County of northwest Colorado, United States.
This geographical formation was originally named "Echo Rock" in John Wesley Powell's 1875 report, The Exploration of the Colorado River and Its Canyons.
The Steamboat name first appeared on a 1941 United States Geological Survey map of Dinosaur National Monument.
Steamboat Rock is a mile-long, 1,000-ft high, slender peninsular ridge within a meander of the Green River.
It is composed almost entirely of Permian-Pennsylvanian Weber Sandstone, with a thin layer of Park City Formation caprock.
