2018 Map of North Canyon Point

About this map

Grand Canyon National Park forms the heart of this landscape, where the high desert of House Rock Valley meets the dramatic vertical drop of Marble Canyon. This 2018 survey documents the river corridor as it existed in the early twenty-first century, tracing the Colorado River as it winds through deep-cut gorges. The map provides precise locations for several dangerous river features, including Hansbrough-Richards Rapid, Twentyfive Mile Rapids, and Twentynine Mile Rapids. Away from the river, the terrain rises toward North Canyon Point, where ephemeral drainage systems like N-Canyon-Wash and Shinumo Wash carve through the plateau. These washes are vital indicators of the region's hydrologic patterns, essential for understanding the seasonal water flow that has shaped the Arizona desert over millennia.
