2021 Map of Powell Plateau

USGS Topo · Published 2021

About this map

Grand Canyon National Park encompasses this entire landscape, defined by the winding course of the Colorado River and its dramatic vertical transitions. The northern reaches are dominated by Great Thumb Mesa and Great Thumb Point, leading toward the expansive Powell Plateau. Along the river’s path, the Middle Granite Gorge cuts deep through the canyon floor, marked by hazardous points such as Tapeats Rapids, Bedrock Rapids, and Deubendorff Rapids. High above the water, numerous terraces like Feroz Terrace, Specter Terrace, and Alarcon Terrace provide distinct geological steps. The map also traces the Colorado River Trl as it follows the river's edge through Specter Chasm, while named drainages like Hakatai Canyon and Blacktail Canyon reveal the intricate erosion patterns of this desert terrain.
