Penon Blanco Road (Mariposa County)

[Max Rockatansky]

Penon Blanco Road is an approximately 4.5 mile rural one-lane highway located in the Coulterville area of Mariposa County.  This highway is named after the ghost town of Peñón Blanco and was once part of a cutoff from Don Pedro Bar to Big Oak Flat.  The Peñón Blanco town site was established near the namesake Peñón Blanco Mine in 1849.  The Peñón Blanco Mine extracted hard rock gold ore which would consume the town site during the 1860s.
