Read Powellâs account of the first ever river expedition through the Grand Canyon in The Exploration of the Colorado River and Its Canyons, issued as a Penguin Classic in 2003.
The Grand Canyon of the Colorado River is a mile-deep, (1.6 km) and creates a barrier that bisects the park. Even though the average distance across the canyon is only 10 miles/ 16 km, be aware that it is a five-hour drive of 220 miles/ 354 km between the park's South Rim Village and the North Rim Village. Scenery, climate and vegetation are noticably different between north and south rims because of differences in elevation.
