2011 Map of Hidden Valley

About this map

Hidden Valley defines this arid landscape in La Paz County, where a complex network of seasonal drainages carves through the terrain. The hydrological patterns are dominated by the significant Lopez Wash in the north and the expansive Yuma Wash system to the southeast. These ephemeral waterways, including the West Fork Yuma Wash and Clip Wash, indicate a region shaped by sudden desert runoff rather than permanent surface water. The absence of developed roads or settlements in this 2011 survey underscores the area's isolation and its preservation as an undisturbed natural basin. For researchers, the map provides a precise record of these shifting sandy channels, which often serve as the primary landmarks in an otherwise featureless desert environment, where Red Cloud Wash traces its way toward the southern boundary.
