1952 Map of Mouth of Dark Canyon

About this map

Colorado River currents carve through the deep gorges of Cataract Canyon in this early 1950s survey of the high desert. The landscape is defined by massive sandstone features like the Dark Canyon Plateau and dramatic overlooks at Ocean Point and Bowdie Point. Navigational hazards such as the Dark Canyon Rapids are clearly marked where the canyon mouth meets the river, while inland, the terrain breaks into complex drainages including Lost Canyon and Lean-To Canyon.
