Canyonlands National Park, a unit of the National Park System in southeastern Utah. The park is in a rocky, desert region and covers 337,570 acres (136,716 hectares). Here the Colorado and Green rivers converge, forming a Y that divides the park into three districts.

In the north, between the rivers, is the Island in the Sky district, made up mostly of flat-topped mesas that reach as high as 6,300 feet (1,920 m). In the southwest is an isolated area of twisting and turning canyons known as the Maze district. The Needles district, in the southeast, was named for its numerous sandstone towers and spires. In this region are petroglyphs left by American Indians 700 to 1,200 years ago. Canyonlands was established as a national park in 1964.
