Round Mountain Road


Round Mountain Road is an approximately 19-mile highway located in the foothills of the Sierra Nevada Mountains northeast of Bakersfield.  Round Mountain Road begins at China Grade Loop at the Kern River near the site of Gordon's Ferry and terminates at Granite Road.  The Round Mountain Road corridor incorporates parts of the 1850s-era stage route known as the Stockton-Los Angeles Road in the form of Gordon‘s Ferry and Posey Station.  Modern Round Mountain Road emerged following the discovery of the Kern River Oil Field during 1899 and the Round Mountain Oil Field during 1927. 


Part 1; the history of Round Mountain Road and the Stockton-Los Angeles Road

The Stockton-Los Angeles Road came into use after the 1853 Kern River Gold Rush began.  The Stockton-Los Angeles Road was a replacement of the earlier El Camino Viejo.  Unlike the El Camino Viejo the Stockton-Los Angeles Road avoided the dense Tule Marches in San Joaquin Valley.  The Stockton-Los Angles Road stayed close to the Sierra Nevada Mountain foothills near the new claims on the Kern River watershed.  The corridor of Stockton-Los Angeles Road was also part of the 1858-61 alignment of the southern Butterfield Overland Mail Route.  

The formation known as the China Grade was used by the Stockton-Los Angeles Road to descend the Kern River Bluff to Gordon's Ferry at the Kern River.  From Gordon's Ferry the Stockton-Los Angeles Road followed the foothills of the Sierra Nevada Mountains to reach Posey Station (also known as Poso Flat) at Poso Creek.  The Stockton-Los Angeles Road can be seen utilizing China Grade and Gordon's Ferry to reach Posey Station on the 1857 Britton & Rey's map of California

The popularity of the Stockton-Los Angeles Road began to decline rapidly as the Central Pacific Railroad through San Joaquin Valley was built through the 1870s.  Farm diversions for irrigation in San Joaquin Valley and the presence of various rail sidings along the Central Pacific Railroad spurred infrastructure development which made development through previous wetlands easier.  

During the 1870s Chinese settlers in the Bakersfield area improved the route of the Stockton-Los Angeles Road down the Kern River Bluff.  These settlers used the Kern River Bluff to search for watercress along the Kern River in the vicinity of location of Goron's Ferry.  In time the route down the Kern River Bluff came to be known as the China Grade in reference to the settlers who improved it.  In 1899 the Kern River Oil Field was discovered north of the Kern River Bluff and the China Grade an important access route to reach it.  

The 1898 Walkup Map of Kern County depicts the waning years of the Stockton-Los Angeles Road between Gordon's Ferry and Posey Station.  The Stockton-Los Angeles Road can be seen crossing the Kern River from the China Grade at Township 29, Range 28.  The Stockton-Los Angeles Road is shown continuing north to the vicinity of Posey Station via Granite Station.  From Granite Station the Stockton-Los Angeles Road is shown continuing north to the Tulare County line by way of the outskirts of Woody.  Much of the Stockton-Los Angeles Road north of the Kern River is displayed as a trail denoting the declining importance of the corridor.  




During the 1910s the China Grade was improved by Kern County and a bridge was installed at Gordon's Ferry to permit east access the Kern River Oilfield and the so-called "Oil City."  Below the China Grade (now part of Alfred Harrell Highway) can be seen snaking down the Kern River Bluff in a 1910-1915 era photo from the Antique Collection of Michael J. Semas Facebook Page.


Round Mountain Road can be seen connecting the Oil City near Gordon's Ferry to Granite Road on the 1917 California Automobile Association Map.  Much of the previous routing of the Stockton-Los Angeles Road between Gordon's Ferry and Posey Station appears to have been repurposed for oil exploitation.  


The original Kern River Bridge at Gordon's Ferry can be seen below in a photo dated to 1918.

The Round Mountain Oil Field was discovered during 1927 which led to a further reemergence of the Round Mountain Road corridor.  Production in the Round Mountain Oil Field peaked during 1938 when 5,453,194 barrels were pumped.  Discoveries of new wells in the Round Mountain Oil Field continued until 1974.  

Round Mountain Road and the 1,612-foot-high peak of Round Mountain can be seen linking Oil City to Poso on the 1935 Division of Highways Map of Kern County.  




Part 2; a drive on Round Mountain Road

A plaque pertaining to the history of Gordon's Ferry can be found on China Grade Loop approaching the Kern River and beginning of Round Mountain Road.  Gordon's Ferry was an overhead cable driven ferry which was part of the Stockton-Los Angeles Road and saw use as part of the Butterfield Overland Mail Route from 1858-1861.  



China Grade Loop crosses north over the Kern River and intersects Round Mountain Road.


Round Mountain Road northbound begins with a right-hand turn from China Grade Loop.  Traffic is advised Round Mountain Road is prone to flooding. 


Round Mountain Road initially follows the Kern River eastward and the Oil City to Choctaw Valley as a two-lane roadway.  East of Choctaw Valley Road, Round Mountain Road narrows to a wide single-lane roadway.




























Round Mountain Road turns north from the Kern River and ascends to a bluff overlooking Ming Lake of Hart Memorial Park.  Lake Ming was completed during 1959 when Hart Memorial Park reached it's present size. 






Round Mountain Road ascends to a bluff located at approximately 1,400 feet above sea level and approaches Round Mountain.  





















Round Mountain Road descends through the oil wells of the Round Mountain Oil Field to Poso Creek.  At Poso Creek the grade of Round Mountain Road expands back to two-lanes. 
























Round Mountain Road follows Poso Creek to a terminus at Granite Road (former California State Route 155).









A historic plaque pertaining to Posey Station can be found at the intersection of Round Mountain Road and Granite Road.  Posey Station was one of six stagecoach stations on the Butterfield Overland Mail Route located in Kern County.  Posey Station was located on what is now Round Mountain Road approximately 1.5 miles east of Granite Road along Poso Creek.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
