About this map

Kofa National Wildlife Refuge dominates this desert landscape in Yuma County, capturing the arid expanse of the King Valley as it appeared in the late 20th century. The terrain is defined by the sharp transition from the valley floor to the prominent peaks of the Castle Dome Mountains in the southwest corner. Human presence is sparse, marked primarily by essential water sources and remote landmarks such as Kofa Deep Well and the Rob Roy site. These features, along with Little White Tanks and Figueroa Tank, highlight the critical importance of water management in this environment. The King Road provides the primary transit corridor through the refuge, connecting these isolated points across the open desert. This document preserves the topographical details of a protected wilderness area during a period of limited revision and field checks, offering a precise look at the drainage patterns and landforms of the Arizona desert.
