About this map

The Colorado River and its massive canyon systems define this late 19th-century survey of northwestern Arizona. Long before the region was reshaped by modern infrastructure, the landscape was charted by the Powell Survey, emphasizing the dramatic verticality of features like Hurricane Ledge and the Grand Wash Cliffs. This period of exploration captures the remote territory of Mohave when travel was dictated by scattered water sources such as Pakoon Spring, Cane Spring, and Witch Pool.

In the eastern half of the map, the Uinkaret Plateau is punctuated by prominent volcanic peaks, including Mt Trumbull, Mt Logan, and Mt Emma, which tower over the Toroweap Valley. To the west, the Virgin River snakes near the settlement of Beaverdam and the Virgin Mountains. A critical river crossing of the era is preserved at Pierce Ferry, providing a look at the historical transit network across the canyons during the frontier years.
