Canyonlands National Park in southeastern Utah is known for its dramatic desert landscape carved by the Colorado River. Island in the Sky is a huge, flat-topped mesa with panoramic overlooks. Established in 1964, the park preserves 527 square miles of colorful landscape that has eroded into countless canyons, mesas, arches, and buttes by the Colorado River and its tributaries. The Colorado and Green rivers divide the park into four districts: Island in the Sky, the Needles, the Maze, and the rivers themselves. While these areas share a primitive desert atmosphere, each retains its own character and offers different opportunities for exploration.
