About this map

Prescott National Forest dominates this mid-century survey, revealing a landscape defined by mining claims and forest management within the Bradshaw Mountains. Higher elevations are marked by the Mt Union Lookout and Groom Creek Ranger Sta, while the rugged terrain is home to established camps like Camp Wamatachick and the Phoenix YMCA Camp. The map provides a detailed look at the era's mining activity, specifically naming sites such as the Jersey Lily Mine, California Mine, and Snowdrift Mine.

Settlement patterns follow the narrow valleys and ridges, with Groom Creek, Walker, and Venezia serving as focal points. The presence of the Palace Station and the Goodwin PO suggests long-standing rural infrastructure for mail and travel along the Senator Highway. Water sources are critical here, with numerous named springs like Quail Spr and Grapevine Sprs dotting the drainages of the Hassayampa River and Big Bug Creek.
