2012 Map of Explorers Monument

About this map

The Colorado River carves a deep path through Coconino County in this 2012 survey, revealing the complex geological stair-steps of the Grand Canyon’s south rim. The landscape is defined by massive topographic features bearing diverse cultural names, from the ancient Aztec Amphitheater and Montezuma Point to the Darwin Plateau and Evolution Amphitheater. Navigational hazards like Hakatai Rapids and Walthenberg Rapids mark the river’s course, while water sources such as Mystic Spring and Seep Spring provide critical points in an otherwise arid environment.
