This is a look at Bears Ears National Monument in southeastern Utah. It comprises of 1.35 million acres and is jointly managed by the United States Department of the Interior, the United States Forest Service, and the Hopi Tribe, Pueblo Tribes, Navajo Nation, Ute Mountain Ute Tribe and Ute Indian Tribe of the Uintah and Ouray Reservation. The Dark Canyon complex contains unique geology and exposes roughly 250 million years of geologic history, as well as evidences of Ancestral Puebloan occupation. This rugged and remote landscape is abounding with wildlife, such as golden eagles, peregrine falcons, and the Mexican spotted owl.

Petroglyphs, hanging gardens, and deep canyons make this remote landscape a notable part of Bears Ears National Monument.

Deep, meandering canyons cut through the Colorado Plateau in southeastern Utah in this photograph, taken by an astronaut on the International Space Station on April 6, 2023. These canyons, known as the Dark Canyon complex, have distinctive geology, ecology, and archeology. They are some of the only intact protected canyons in the United States.

Bears Ears National Monument is comprised of a total of 1.35 million acres spread across the state of Utah.

This rugged and remote landscape has been shaped by erosion. Over thousands of years, the Colorado River and smaller tributaries have eroded winding, steep-walled canyons into the sedimentary rock. Dark Canyon—one of seven canyons within the complex—cuts diagonally across the photo. Within this canyon, sandstone walls tower up to 3,000 feet (900 meters), shading visitors from morning and afternoon sun—hence its name. The canyon’s steep walls expose roughly 250 million years of geologic history and contain deposits from the Permian period. Cockleshell and crinoid stem fossils have been found in the area.

The monument is jointly managed by the United States Department of the Interior, the United States Forest Service, and the Hopi Tribe, Pueblo Tribes, Navajo Nation, Ute Mountain Ute Tribe and Ute Indian Tribe of the Uintah and Ouray Reservation.

The Colorado River flows in from Canyonlands National Park, located just 6 miles (10 kilometers) northeast of this view. The confluence of the Green and Colorado rivers in Canyonlands creates powerful rapids downriver. This segment of the river—part of Glen Canyon National Recreation Area—is known as Cataract Canyon and is notorious for its hazardous whitewater rafting conditions.

Springs, hanging gardens, riparian areas, and mesas provide habitat for a wide range of wildlife around the Dark Canyon complex. Golden eagles, peregrine falcons, and the Mexican spotted owl have been observed in the complex. Dark Canyon itself extends east beyond the photo into a designated wilderness area in the Manti-La Sal National Forest.

The geology of the Dark Canyon complex consists of sedimentary rocks formed during the Permian period 250 million years ago.

The Dark Canyon complex is part of Bears Ears National Monument, which contains many cultural and archaeological sites. According to a presidential proclamation issued in October 2021, Bears Ears is sacred land to several Tribal Nations and Pueblos. Although Ancestral Puebloan occupation seems to have been somewhat sparser in Dark Canyon compared to canyons farther south, cliff dwellings, petroglyphs, and lithic scatters do exist within this area.

The Colorado River has carved out the winding canyons and deep ravines in the area.

Astronaut photograph ISS069-E-001017 was acquired on April 6, 2023, with a Nikon D5 digital camera using a 400-millimeter lens and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 69 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.

Bears Ears National Monument is home to more than 100,000 Native American cultural sites, including petroglyphs, cliff dwellings, and lithic scatters.
