Nature & Science
Canyonlands National Park preserves one of the last, relatively undisturbed areas of the Colorado Plateau, a geological province that encompasses much of the Colorado River and its tributaries. Carved out of vast sedimentary rock deposits, this landscape of canyons, mesas, and deep river gorges possesses remarkable natural features that are part of a unique desert ecosystem.
The foundation of Canyonlands' ecology is its remarkable geology, which is visible everywhere in cliff profiles that reveal millions of years of deposition and erosion. These rock layers continue to shape life in Canyonlands today, as their erosion influences elemental features like soil chemistry and where water flows when it rains.
Known as a "high desert," with elevations ranging from 3,700 to 7,200 feet above sea level, Canyonlands experiences very hot summers, cold winters and less than ten inches of rain each year. Even on a daily basis, temperatures may fluctuate as much as 50 degrees.
Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals in Canyonlands. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. Scientists believe this and other behaviors signal dominance and facilitate courtship.
