About this map

The Colorado River carves a deep path through this 1967 survey, serving as the primary boundary between Mohave and Coconino counties. The landscape is defined by its extreme topography, where the river meets landmarks like Granite Park and the steep walls of Two Hundred and Ninemile and Indian Canyon. This area represents a point of intersection between Grand Canyon National Park and the Hualapai Indian Reservation, highlighting the administrative and geological complexity of the river corridor.

Evidence of historical exploration and resource extraction is found in isolated sites like the Snyder Mine and Old Bonnie Tunnel, located near the river's edge. These features, along with Stanley Spring and a nameless Trail, provide specific points of interest for researchers tracking early 20th-century activity in the inner canyon. Unique geological formations, such as the Natural Arch near Two Hundred and Fourteenmile Creek, further distinguish this particular stretch of the canyon floor.
