It is largely contained within the Grand Canyon National Park, one of the first National Parks in the United States. The national park service regulates river travel through the Grand Canyon. There are only 16 companies with permits to offer river trips. Park rangers control private rafting trips at entry points. The canyon is 277 miles long, ranges in width from 76 ft. at its narrowest point to 18 miles at its widest; it attains a depth of over a mile approx. 6000 feet from rim to valley floor. The depth varies from inches to about ninety feet. The volume of water running through the canyon, thus how high on the banks the water gets, is determined by how much is released from Glen Canyon Dam, located in Utah, which is in response to the demands for hydroelectric power in the west. Water released from the Glen Canyon Dam is about 46 degrees f in the summer; colder in the winter. The water drops a total of 1,709 feet in 296 miles (includes Marble Canyon), averaging 8 ft per mile, nearly 25 times that of the Mississippi. While the specific geologic processes and timing that formed the Grand Canyon is the subject of debate by geologists, recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago. Since that time, the Colorado River continued to erode and form the canyon to the point we see it as today. Before European immigration, the area was inhabited by Native Americans who built settlements within the canyon and its many caves. They considered the Grand Canyon a holy site and made pilgrimages to it. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
