2015 Map of Horsecamp Mountain

About this map

Bailey Flats and Grub Gulch anchor this 2015 topographic study of the foothill transition between the Chowchilla River and Fresno River basins. The terrain is defined by prominent peaks including Horsecamp Mountain, Twin Sisters, and Buckeye Mtn, with a network of rural routes such as Old Wagon Rd and Ellerbrock Station Rd tracing the historical paths through Mariposa and Madera counties. Local-history researchers will find interest in the mapping of Specimen Springs and the Grupe Ranch Airport, along with the complex drainage of the W Fork, Middle Fork, and E Fork Chowchilla River. The landscape reveals a pattern of dispersed settlement and agricultural land use typical of the Sierra Nevada foothills, marked by ranch roads like Polk Ranch Rd and JWP Ranch Rd.
