BRYCE CANYON
It is located in southwestern Utah in the United States. The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocksprovide spectacular views for park visitors. Bryce sits at a much higher elevation than nearby Zion National Park. The rim at Bryce varies from 8,000 to 9,000 feet (2,400 to 2,700 m).The Bryce Canyon area was settled by Mormon pioneers in the 1850s and was named after Ebenezer Bryce, who homesteadedin the area in 1874.
WHAT IS THE HISTORY OF THE BRYCE CANYON?
Little is known about early human habitation in the Bryce Canyon area. Archaeological surveys of Bryce Canyon National Park and the Paunsaugunt Plateau show that people have been in the area for at least 10,000 years. Basketmaker Anasazi artifacts several thousand years old have been found south of the park. Other artifacts from the Pueblo-period Anasazi and the Fremont culture (up to the mid-12th century) have also been found. The Paiute Indians moved into the surrounding valleys and plateaus in the area around the same time that the other cultures left. These Native Americans hunted and gathered for most of their food, but also supplemented their diet with some cultivated products. The Paiute in the area developed a mythology surrounding the hoodoos (pinnacles) in Bryce Canyon. They believed that hoodoos were the Legend People whom the trickster Coyote turned to stone.
WHAT IS THE GEOLOGY OF THE BRYCE CANYON?
The Bryce Canyon area shows a record of deposition that spans from the last part of the Cretaceous period and the first half of the Cenozoicera. The ancient depositional environment of the region around what is now the park varied. The Dakota Sandstone and the Tropic Shale were deposited in the warm, shallow waters of the advancing and retreating Cretaceous Seaway (outcrops of these rocks are found just outside park borders). The colorful Claron Formation, from which the park's delicate hoodoos are carved, was laid down as sediments in a system of cool streams and lakes that existed from 63 to about 40 million years ago (from the Paleocene to the Eocene epochs). Different sediment types were laid down as the lakes deepened and became shallow and as the shoreline and river deltas migrated.Several other formations were also created but were mostly eroded away following two major periods of uplift. The Laramide orogenyaffected the entire western part of what would become North America starting about 70 million to 50 million years ago.
