was authorized on this date 40 years ago. From the National Park Service:
Canyonlands National Park preserves a colorful landscape of sedimentary sandstones eroded into countless canyons, mesas and buttes by the Colorado River and its tributaries. The Colorado and Green rivers divide the park into four districts: the Island in the Sky, the Needles, the Maze and the rivers themselves. While the districts share a primitive desert atmosphere, each retains its own character and offers different opportunities for exploration and learning.
