A powerful and inspiring landscape, the Grand Canyon overwhelms our senses through its immense size; 1,218,375 acres in area, 277 river miles long, up to 18 miles wide, and a mile deep. It is a World Heritage Site, and lies on the Colorado Plateau in northwestern Arizona. Drainage systems have cut deeply through the rock, forming steep-walled canyons.
