2021 Map of Illinois Hill

About this map

White Rock Cem sits as a quiet landmark within this high-elevation landscape of the Sierra Nevada foothills, situated just south of Brushy Canyon. This 2021 survey reveals a terrain defined by prominent geological features, including the eponymous Illinois Hill and the distinctive Cow and Calf Mtn. The area is carved by a network of seasonal watercourses such as Mariposa Cr, Ganns Cr, and Deadman Cr, which dictate the winding paths of rural routes like White Rock Rd and W Westfall Rd. The map provides a detailed look at the public land survey system, showing the intersections of townships like t7s r17e and t7s r18e. These surveying boundaries, coupled with named peaks like Quartz Rock and Copper Hill, offer a precise geographical framework for local historians and researchers tracking property lines or physical landmarks in this part of Mariposa County.
