Merriam Crater and Merriam Mountain anchor this high-desert volcanic field in Coconino County, characterized by a dense concentration of cinder cones and drainage washes. The landscape is defined by its distinct geological formations, including the twin heights of North Sheba Crater and South Sheba Crater, alongside the prominent Maroon Crater. Human presence is minimal and largely centered on land management and ranching infrastructure, evidenced by the Rock House in the southeast and water management features like the Rio de Flag Trick Tank and Cone Water Tank.
