Aztec Butte is a sandstone summit, elevation 6,312 feet (1,924 meters), located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah.[3] Aztec Butte is composed of white cross-bedded Navajo Sandstone, which is the remains of wind-borne sand dunes deposited approximately 170 million years ago during the Jurassic Period. It resembles the Pyramid of the Sun in Mexico, which was built by the Aztecs.[4]

Ancestral Puebloan people traveled to the Island in the Sky area to hunt and gather seeds, then stored their food in stone granaries near the top of Aztec Butte. These well-preserved granaries date to AD 1200–1300.[5] A half-mile hiking trail through flat grassland, followed by a quarter-mile scramble with 200 feet vertical gain, leads to the top of the butte and the granaries. The trailhead is located alongside the road to Upheaval Dome. In addition to Upheaval Dome, other nearby attractions include Mesa Arch which is situated less than 1 mi (1.6 km) to the southeast, Muffin Butte to the south, Green River Overlook to the southwest, and Trail Canyon to the north. Precipitation runoff from Aztec Butte drains to the Green River.
