Echo Park (Colorado) is a remote river bottom surrounded by canyon walls on the Green River in Dinosaur National Monument. It was first mapped and given its name by the Powell Geographic Expedition in 1869. A proposed dam at Echo Park turned into a nationwide environmental controversy in the early 1950s. The Sierra Club and other conservationist groups helped forge a compromise in Congress that eliminated the Echo Park Dam from the Colorado River Storage Project Act of 1956.
