Aztec Butte is a sandstone summit, elevation 6,312 feet, located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah. 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.
