2021 Map of Grand Falls

About this map

The Little Colorado River defines the arid landscape of this Coconino County terrain, carving a winding path through the volcanic and sandstone formations of the high desert. The river's most significant geographic break occurs at Grand Falls, a massive tiered drop created by prehistoric lava flows. This survey by the U.S. Geological Survey details the complex drainage network feeding into the river, including the Dinnebito Wash and Little Roden Wash, which underscore the region's intermittent water systems. Movement through this remote area is facilitated primarily by tribal road networks like Indian Rte 6910 and Indian Rte 6732, connecting the township boundaries of T24N and T25N. These corridors provide a look at the modern land management within the Navajo Nation, where vital resources like the Muddy Tank support the local livestock and ranching traditions.
