1988 Map of Hancock Knolls

About this map

Grand Canyon National Park occupies the southern and eastern margins of this Arizona landscape, where the plateau drops away into the complex drainages of Tuckup Canyon and Little Robinson Canyon. The topography is defined by the prominent Hancock Knolls, a series of high points including the specific peak at Hancock Knoll. This 1988 provisional survey captures a remote section of Mohave County during a period of land management transition, showing the infrastructure of the ranching era through water features like White Tank and School Section Tank. The mapping emphasizes the relationship between the relatively flat upper plateaus and the sudden, deep incisions of the canyon systems, providing a detailed record of the unimproved trails and livestock tanks that supported desert operations on the Arizona Strip.
