Arches National Park
Arches National Park preserves over two thousand natural sandstone arches, including the world-famous Delicate Arch, in addition to a variety of unique geological resources and formations. In some areas, faulting has exposed millions of years of geologic history.The extraordinary features of the park, including balanced rocks, fins and pinnacles, are highlighted by a striking environment of contrasting colors, landforms and textures.

Bryce Canyon National Park
At Bryce Canyon National Park, erosion has shaped colorful Claron limestones, sandstones, and mudstones into thousands of spires, fins, pinnacles, and mazes. Collectively called "hoodoos," these colorful and whimsical formations stand in horseshoe-shaped amphitheaters along the eastern edge of the Paunsaugunt Plateau in Southern Utah.

Canyonlands National Park
Canyonlands National Park preserves a colorful landscape of sedimentary sandstones eroded into countless canyons, mesas and buttes by the Colorado River and its tributaries. Located in southeast Utah, the park sits in the heart of a vast basin bordered by sheer cliffs of Wingate Sandstone.

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 the study of natural and cultural history.

Most visits to Canyonlands involve camping along the trails, roads and rivers found here. The four districts are not directly linked by any roads, so travel between them requires two to six hours by car. Generally, people find it impractical to visit more than one or two districts in a single trip.

Capitol Reef National Park
The Waterpocket Fold, a 100-mile long wrinkle in the earth's crust known as a monocline, extends from nearby Thousand Lakes Mountain to the Colorado River (now Lake Powell). Capitol Reef National Park was established to protect this grand and colorful geologic feature, as well as the unique historical and cultural history found in the area.

Zion National Park
Zion is an ancient Hebrew word meaning a place of refuge or sanctuary. Protected within the park's 229 square miles is a dramatic landscape of sculptured canyons and soaring cliffs. Zion is located at the junction of the Colorado Plateau, Great Basin and Mojave Desert provinces. This unique geography and the variety of life zones within the park make Zion significant as a place of unusual plant and animal diversity.
