About this map

The Black Mountains dominate this high-desert terrain in Iron County, providing a stark topographical backdrop to a region defined by its vital water sources. The landscape is punctuated by numerous springs and seeps, such as Jack Henry Seep and Guyman Seep, which have historically served as essential watering points in this arid environment. These water features, including Ryan Spring and Lister Spring, dictate the movement of both wildlife and human activity through the rugged corridors of Cottonwood Canyon and Poorman Ranch Canyon.

Transport through the area is marked by a network of ranch roads and specialized paths like the Poorman Ranch Canyon Loop and N Hills Beach Rd, reflecting the land's use for grazing and exploration. To the south, the terrain transitions toward the Red Hills and the edge of the Parowan Valley, where drainage systems like Kane Spring Wash and Jackrabbit Wash channel seasonal runoff from the higher elevations of Chipman Peak and the surrounding ridgelines.
