About this map

Granite Gorge dominates this 1967 survey of the Arizona backcountry, where the Colorado River winds through a sequence of treacherous whitewater features within the Lake Mead National Recreation Area. The map documents a rugged landscape defined by river-mile navigation, noting specifically named hazards like Separation Rapids, Gneiss Canyon Rapids, and Bridge Canyon Rapids. High above the river, a Historical Marker sits near the head of Separation Canyon, signifying the area's importance in early exploration and Colorado River history.
