A Barstow Narrative

Barstow, California, from the 1870s through the present, with all key details preserved and arranged chronologically:

Barstow stands today at the center of the Mojave Desert’s long story of ranching, mining, railroads, and highways. Its history reflects the layered development of the Mojave River corridor, where water, transportation, and enterprise have drawn people across the desert for more than a century and a half.

Mojave River

In the years following the Civil War, the upper Mojave River region supported a few scattered cattle ranches and wagon stations. Before Barstow existed, the country between Oro Grande and Daggett was known for its open range and desert pastures. Herds were grazed along the Mojave River, using its shallow pools, seeps, and hand-dug wells. During the 1870s and 1880s, ranchers moved stock between the high country of the San Bernardino Mountains and the desert valleys, following trails that paralleled the river. Stations at places such as Lane’s Crossing and Fish Ponds served as watering points for stock and travelers. As the Santa Fe Railroad advanced across the desert, freight access to distant markets encouraged limited agriculture along the riverbanks. By the early 1900s, alfalfa, grain, and small orchards appeared in Victor Valley, and a few experimental plots extended downstream toward Barstow. The Arrowhead Reservoir and Power Company began purchasing riparian tracts between Victorville and Barstow to secure water rights, recognizing that the Mojave River would control the future of settlement. Though the arid climate limited cultivation, these early ranches and farms laid the foundation for the region’s first lasting economy before industry and highway travel arrived.

Fish Ponds

Barstow’s founding dates to the early 1880s, when the Atlantic & Pacific Railroad, later part of the Atchison, Topeka & Santa Fe system, pushed its line westward from Needles toward Mojave. In 1883, the mainline was completed across the desert, and a division point was established to centralize maintenance, crew changes, and fueling. This camp, called initially Waterman Junction, became the nucleus of Barstow. The town was renamed in 1884 for William Barstow Strong, president of the Santa Fe, and quickly became the railroad’s desert headquarters. Roundhouses, repair shops, and supply depots were built to serve the trains moving freight and passengers across the Mojave.

Santa Fe

While Barstow developed as a railroad town, the nearby community of Daggett became the milling and shipping center for the Calico silver mines. The Calico district boomed in the early 1880s, with more than a hundred mines producing ore that was hauled to Daggett for reduction and shipment east. In 1898, a short branch line was built from Daggett to Calico to carry ore directly to the Santa Fe main line. This small spur improved mining transport but did not found Barstow; the town was already well established as a division headquarters long before. Barstow’s location on the main transcontinental line—roughly midway between San Bernardino and Needles—gave it strategic importance that would outlast the mining booms around it.

Daggett, CA

As the 1890s ended and silver prices dropped, mining declined, but the railroad presence ensured Barstow’s survival. The town expanded with railroad housing, stores, and services for workers and travelers. The Mojave River valley became a modest agricultural district, producing hay, fruit, and dairy products for local use. By 1910, Barstow had schools, churches, and small businesses serving both rail employees and the surrounding ranch country.

Casa del Desierto, Harvey House

In 1911, the Fred Harvey Company constructed the Casa del Desierto, a grand Mission Revival depot and Harvey House that brought elegance and permanence to the desert town. The building served as a hotel, restaurant, and railroad office, offering travelers comfort along the route between Los Angeles and the Colorado River. It quickly became Barstow’s social center and symbol of progress. The Santa Fe expanded its shops, roundhouse, and yards, reinforcing the town’s position as a key maintenance and operating base.

El Garces, Harvey House

At the same time, the automobile age arrived. The National Old Trails Highway followed the corridor of the railroad, and by the 1920s, U.S. Route 66 brought a steady stream of motorists through town. Gas stations, garages, and cafes appeared along the main street, which paralleled the railroad tracks. Barstow became a vital service stop for travelers crossing the Mojave Desert, bridging two eras of transportation—steam and motor—and transforming from a company town into a crossroads community.

Route 66

The Great Depression slowed new growth, but Barstow endured. The flow of automobiles along Route 66 kept the economy alive, while the railroad continued to carry freight and passengers across the desert. By the late 1930s, the town’s main street was lined with motor courts, diners, and filling stations.

Yermo, CA

World War II brought another surge of activity. Barstow’s location on both the Santa Fe main line and Route 66 made it ideal for military supply and logistics. The Marine Corps established the Nebo Depot just west of town, handling ordnance and supplies for the Pacific war effort. Additional facilities at Daggett and Yermo supported troop movements and desert training exercises. Troop trains, fuel convoys, and war freight filled the region, and the population grew rapidly as railroad workers, servicemen, and civilian contractors arrived.

Calico Ghost Town

By the late 1940s, Barstow had become the true hub of the Mojave. Mining had faded, but rail, highway, and military operations kept the town busy. Route 66 was in its prime, bringing travelers east and west through a landscape alive with neon lights and the constant hum of engines. Barstow’s economy rested on three pillars: the Santa Fe Railroad, the Marine base, and the steady flow of cross-country traffic.

After the war, the new interstate system reshaped the desert. The Marine Corps Logistics Base at Nebo expanded during the 1950s, and the Yermo Annex was developed for vehicle storage and repair. Together, they became major employers for the region. Barstow’s population grew as families settled near the base, supported by trucking companies, service stations, and small industries. Route 66 reached its height during this period, and Barstow’s main street glittered with motels, diners, and bright neon signs welcoming motorists.

Interstate 15 Freeway

By the late 1960s, however, the new Interstate 15 and Interstate 40 began to bypass the older downtown route. Travel patterns shifted, and many classic roadside businesses declined. Still, the same geography that had favored Barstow from the start—its place at the meeting of routes—kept it alive. The Santa Fe Railroad remained one of the town’s largest employers, operating extensive classification yards. The Marine bases continued their vital supply missions, and long-haul trucking replaced some of the lost highway trade.

Harvey Girls

Through the 1970s, Barstow adapted to the new interstate era. Truck stops and logistics centers replaced many of the old motor courts. Route 66, though decommissioned later, remained a nostalgic symbol of the town’s mid-century heyday. The Casa del Desierto depot closed in 1973 when passenger rail service declined, but the building survived. Preservation efforts during the 1980s and 1990s restored it as a civic landmark housing the Western America Railroad Museum and the Route 66 Museum offices. The restored depot reopened to the public, honoring the legacy of the Harvey Girls and the long railroad heritage that gave the town its start.

Forks in the Road

Today, Barstow continues to serve as the crossroads of the Mojave Desert. It stands at the junction of Interstates 15 and 40, serving travelers, truckers, and freight moving between Southern California and the interior West. The BNSF Railway, successor to the Santa Fe, operates one of its largest freight classification yards in town, handling thousands of cars daily. The Marine Corps Logistics Base remains a major employer, linking Barstow to the modern defense and transportation economy.

Though much has changed, the pattern remains the same. The Mojave River still winds below the town, the rails still hum with freight, and the highways still carry travelers across the vast desert plain. Barstow’s story—from cattle ranching and mining to railroads and freeways—reflects the larger history of the Mojave itself: a land shaped by endurance, movement, and the constant meeting of past and present at the desert’s enduring crossroads.

Rare Earths

Mountain Pass, California, is an unincorporated community in San Bernardino County near the Nevada border along Interstate 15. It lies on the south flank of the Clark Mountain Range at about 4,730 feet in elevation. Before its transformation into a rare earth mining hub, Mountain Pass was part of a high desert rangeland used for cattle grazing and seasonal travel.

In the late 1800s, ranchers from Ivanpah and the Mojave River region grazed cattle along the area’s sparse grasslands and natural springs. By the early 1900s, a few homesteads, corrals, and line camps appeared, but permanent settlement was limited due to aridity and isolation. The nearest centers of activity were Cima and Ivanpah, tied to the Union Pacific line.

During the 1920s and 1930s, open-range ranching declined as highway construction and mineral exploration expanded. U.S. Highway 91, built through Mountain Pass in the 1930s, connected Barstow and Las Vegas and reshaped movement across the desert. Prospectors began testing local outcrops for copper, fluorspar, and uranium.

In 1949, while searching for uranium, geologists discovered bastnasite—a mineral rich in rare earth elements. By 1952, Mountain Pass Mine was in production, marking the shift from ranching to mineral extraction. The mine’s bastnasite ore, containing about 7% rare-earth oxides, proved exceptionally rich. Throughout the 1960s, 1970s, and 1980s, Mountain Pass supplied most of the world’s rare earth elements, which are critical for electronics and defense.

Environmental concerns and global competition, particularly from China, led to a decline in the 1990s. A series of wastewater pipeline spills and stricter regulations led to the closure in 2002. Molycorp reopened the site in 2010 but went bankrupt in 2015. MP Materials acquired it in 2017 and restarted production, now emphasizing on-site recycling and domestic refining. Mountain Pass currently produces 10–15 percent of global rare earth supply and remains the only major U.S. operation of its kind.
