About this map

Merriam Crater and the surrounding volcanic field dominate this portion of the Coconino National Forest. The landscape is defined by a dense concentration of cinder cones and distinctive geologic formations, including the prominent Merriam Mtn and The Sproul. These features are connected by a network of rural routes such as Leupp Rd and Co Rd 419, which navigate the high-elevation terrain between the various craters.

In the southern reaches, the San Francisco Wash cuts across the land, providing a rare drainage point in an otherwise arid volcanic environment. Geologists and local historians can trace the naming of multiple peaks, from the pair of North Sheba Crater and South Sheba Crater to family-named landmarks like Campbell Crater and Francis Crater. The layout of the roads reflects the modern ranching and transit needs of this section of Coconino County.
