Gates of Lodore, Canyon landform in Colorado, United States

Gates of Lodore is a canyon landform in Colorado, United States, where the Green River enters a deep gorge. The site features high rock walls that rise sharply from the water, creating a narrow passage that marks the start of Dinosaur National Monument's canyon section.

The Gates of Lodore were named by John Wesley Powell in 1869 during his famous expedition down the Green and Colorado rivers. The site later became part of Dinosaur National Monument, established in 1915, which helped protect the canyon and its surroundings.

The name of the Gates of Lodore comes from a poem by Robert Southey, which was applied by John Wesley Powell during his exploration. Today, the site is a landmark for river runners, who often pause to admire the entrance and share stories of the journey ahead.

Access to the Gates of Lodore is via a dirt road that leads to a put-in point for river trips, with limited facilities available. Visitors should check road conditions and weather before heading out, as the area is remote and services are scarce.

The canyon walls at the Gates of Lodore expose rock layers that date back millions of years, offering a visible record of ancient environments. The site is also a starting point for multi-day river trips through the monument, attracting adventurers from far and wide.
