1957 Map of Hedgpeth Hills

About this map

Thunderbird Park and the rugged Hedgpeth Hills dominate this portion of Maricopa County during a period of rapid suburban expansion. While the northern landscape is defined by desert peaks like West Wing Mountain and Pyramid Peak, the southern half shows the encroachment of the Glendale urban area, marked in purple revisions from the early 1970s. The Arizona Canal and drainage features like Skunk Creek and New River provide the critical water infrastructure for this arid region. Local community landmarks include the Sierra Vista School and an Amphitheater within the park. This survey captures the transition from open desert flats like Biscuit Flat and Weir Valley to organized residential grids along Union Hills Drive and Bell Road.
