2018 Map of Powell Plateau

About this map

The Colorado River carves a deep path through Middle Granite Gorge and Granite Gorge, creating a dramatic vertical landscape within the Grand Canyon National Park. This 2018 survey detail captures the intricate topography of the canyon walls, where a series of named terraces including Tapeats Terrace, Feroz Terrace, and Alarcon Terrace step down toward the river. High points such as Steamboat Mtn and Great Thumb Mesa overlook the river's descent through treacherous stretches like Tapeats Rapids, Deubendorff Rapids, and Bedrock Rapids.
