Triangle Road (Mariposa County)


Triangle Road is an eleven-and-a-half-mile rural highway located in Sierra Nevada range of Mariposa County.  The corridor begins at California State Route 140 near the community of Midpines and serves as a cutoff of Mariposa which connects south to California State Route 49.  The corridor was north of Darrah was developed in 1912 in to serve as a fire road and was circa 1936-1937.  Pictured is the blog cover is the Snow Creek Bridge near the community of Darrah. 




Part 1; the history of Triangle Road

The development of early Triangle Road is tied to the history of rural community of Darrah near Snow Creek and Buckingham Mountain.  The community was based around the landholdings of Richard Darrah which began to see substantial growth in the 1870s.  The Snow Creek School (later Mount Buckingham School) would open in 1878, and the community would obtain Post Office Service in 1880. 

Triangle Road can be seen complete north from the Chowchilla School (where the road now meets California State Route 49) to Darrah on the 1897 United States Geological Survey of Yosemite.  Jerseydale Road can be seen branching north of Darrah towards said namesake community.  


The surveying and construction of Triangle Road north of Darrah was conducted during 1912 by a company out of Bootjack.  The purpose of the corridor was to serve as a fire road which would shield the densely developed areas of Mariposa County.  

The extension of Triangle Road northwest to California State Route 140 near Midpines was surveyed in January 1936.  Mariposa acquired the necessary right of way during February 1936 and construction would break ground during the following November.  The corridor was developed as a Civilian Conservation Corps project out of Camp Bootjack and included a new bridge over Snow Creek.  The extension was announced as having an anticipated completion by November 1937.

The completed extension of Triangle Road north of Darrah appears on the 1947 United States Geological Survey map of El Portal.   The extension is shown to run south of Buckingham Mountain.




Part 2; a drive on Triangle Road

Southbound Triangle Road can be accessed from California State Route 140 near Midpines. 



Triangle Road ascends to a ridge which overlooks the Bootjack area.  







Triangle Road descends to the Snow Creek Bridge with Buckingham Mountain looming overhead.  The Arc Deco design of the Snow Creek Bridge easily places it to the era of Civilian Conservation Corps construction.  















Triangle Road passes through the community of Darrah and intersects the namesake Darrah Road.  


Triangle Road continues south from Darrah and terminates at California State Route 49.

Madera County Road 607 and the Stockton-Los Angeles Road

Madera County Road 607 is an approximately seven-mile rural unsurfaced highway which spans from Road 600 near Raymond west to Road 29.   Road 607 west from Raymond Road Cemetery (established in 1905) is part of the Stockton-Los Angeles Road corridor surveyed in 1853. The corridor lies in the gap between Fresno Crossing at the Fresno River west to Newton's Crossing at the Chowchilla River. The Buchanan Copper Mine would be along what is now Road 607 in the namesake Buchanan Hollow during July 1863. The Buchanan Mine is thought to have once had a population of between 1,000-1,500 residents by the early 1870s. Copper prices would decline in the decade after the Civil War and much of the activity at Buchanan shifted towards cattle ranching. The last businesses in the community would shutter during World War II and it is now a true ghost town.

Old US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road. US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition. USends.com on US 60 endpoints 1934 State Highway Map Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map.
