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?
Pinyon pines do not produce pine nuts every year. These delicious nuts can only be harvested every three to seven years. This irregular schedule prevents animals from adapting to an abundance of pine nuts and guarantees that at least some nuts will become new pine trees instead of a quick meal.
