About this map

Skeleton Mesa and Big Point dominate the southern half of this landscape on the Arizona-Utah border, representing the high-elevation plateaus that define this portion of Navajo County. The map documents a rugged drainage network where W Copper Cr and E Copper Cr have carved deep incisions into the earth, forming the East Fork Copper Canyon and West Fork Copper Canyon. These topographical features are connected by remote transportation routes including Indian Rte 6450 and Indian Rte 6440, which follow the natural contours of the mesas.

Historical landmarks like Hoskinnini Mesa and Nokai Mesa appear alongside named geographical transitions such as The Ramp and Todicheenie Bench. The drainage patterns and canyon systems captured here provide essential context for understanding the high-desert hydrology and cattle-ranching history of this borderland region, where the state line divides the territory of San Juan Co and Navajo County.
