  • Boron, California

    Historical Timeline

    Pre-1900s: Long before mining arrived, Native American groups like the Kawaiisu and Panamint Shoshone traveled through the area, using seasonal springs and trading routes across the western Mojave Desert.

    1905: Amargo rail siding popped up along the Los Angeles and Salt Lake Railroad line. It mostly served borate shipments from nearby mines like Borate and played a minor role in desert freight traffic.

    1913: Dr. J.K. Suckow, a homesteader and geologist, drilled a water well near Boron and hit a strange white mineral instead — colemanite, a borate ore. He had stumbled onto one of the richest borate deposits in the world.

    1925: A large-scale borax deposit was confirmed in the area. This set off a new development chapter as mining companies raced to secure land and mineral rights. The town of Boron was born around this effort.

    1927: The Pacific Coast Borax Company opened a mine and began full-scale operations. A mill and housing followed quickly, forming the roots of what became a tight-knit mining town.

    1930s–40s: Boron continued to grow with steady borax production. During World War II, borates were vital in producing glass, steel, and other military materials, making the town strategically important.

    1957: U.S. Borax, which had taken over operations, opened the Borax Visitors Center to showcase the mineral’s and industry’s significance to the public.

    1961: NASA began testing rocket engines and aircraft nearby at the Boron Federal Aviation Facility, later used by Edwards Air Force Base. The open land and clear skies made it ideal for aerospace development.

    1970s–1980s: Boron became famous for having the largest open-pit borax mine in the world—a giant hole in the desert with a global economic impact. Most of the world’s borates came out of this little town.

    1990s: Rio Tinto Minerals, an international mining company, acquired U.S. Borax. The site remained one of the company’s most productive and technologically advanced operations.

    2000s–2010s: Boron remained focused on mining, but the town faced challenges as automation reduced jobs and younger generations left for opportunities elsewhere.

    Present Day: Boron is still home to one of the world’s largest borate mines. The town has a museum, a tight-knit community, and a front-row seat to the blend of industrial history and desert resilience. Mining built everything—from streets to schools—and the desert continues to shape daily life.

  • California City, California

    Historical Timeline

    1776: Spanish missionary Francisco Garcés passed through the area during the Juan Bautista de Anza expedition. He camped at Castle Butte, not far from where California City now stands.

    Late 1800s: The land that would eventually become California City was part of the route used by borax freighters. The famous Twenty-Mule Team wagons passed through here, hauling borax to railheads in Mojave.

    1944–1959: During and after World War II, the U.S. military used this desert as a training ground known as the Mojave Gunnery Range “C.” Pilots practiced bombing and strafing runs over the wide open landscape.

    1958: Nat Mendelsohn, a sociology professor and developer, bought 82,000 acres of Mojave Desert with a bold dream — to build a new city to rival Los Angeles. He laid out roads, parks, and even a man-made lake, hoping it would grow fast.

    1960: A post office opened, a small but important step in turning Mendelsohn’s desert dream into a real town.

    1965: California City was officially incorporated on December 10. It had fewer than 1,000 residents but plenty of ambition, with big streets laid out for a population that hadn’t arrived yet.

    1969: Population growth stalled, and some of the early promises hadn’t been delivered. The Federal Trade Commission stepped in to investigate claims that land sales and marketing had been misleading.

    1977: A major settlement forced the development company to repay over 14,000 landowners and build infrastructure that had been promised. At the time, it was the largest FTC case of its kind.

    1999: A large correctional facility was built in California City. It was first used for federal inmates and later leased to the state of California as part of a broader prison reform effort.

    2013: The state leased the prison for $28.5 million a year to help relieve overcrowding in its correctional system. It brought jobs but also sparked debate about the city’s economic direction.

    2016: California City took a step into the cannabis economy by becoming the first in Kern County to allow large-scale commercial marijuana cultivation. It was an effort to create a new revenue stream.

    2023: The correctional facility was shut down when the state ended its lease, leaving behind questions about the city’s next economic chapter.

    Present Day: California City is still one of the largest cities in California by land area, but its population remains modest. It’s a place of wide streets, open skies, and dreams that haven’t quite caught up with the map. Locals work in industries tied to nearby Edwards Air Force Base, the Mojave Air and Space Port, and growing regional industries.

  • Lucerne Valley, California

    Historical Timeline

    Pre-1800s: The Serrano people were the original inhabitants of Lucerne Valley. They lived off the land, gathering desert plants, hunting small game, and traveling between mountain and valley with the seasons. Their knowledge of the land ran deep.

    1867: On February 16, the Battle at Chimney Rock took place. This was one of the last major clashes between Native Americans and settlers in the Mojave Desert. Though the Native defenders fought bravely, they were eventually pushed back.

    1873: Peter Davidson became the first white settler in the area. He set up a homestead at Rabbit Springs and ran a way station for travelers crossing the desert — a lonely but vital outpost.

    1897: James “Dad” Goulding arrived and planted apple trees, vegetables, and alfalfa. Locals began calling the area “Lucerne,” after the French word for alfalfa, which grew well in the valley’s dry soil.

    1912: The growing community held its first July 4th celebration. Around the same time, Lucerne Valley got its own post office — a big step for a frontier town.

    1916: A fierce windstorm sparked a fire that destroyed both Lucerne Valley and Midway schools. Until they were rebuilt, students attended class at Rodman School.

    1920s: Lucerne Valley became a popular spot for filming Westerns with its wide open spaces and rugged scenery. Movie crews brought some extra money and excitement to the otherwise quiet desert.

    1928: Electricity finally came to Lucerne Valley. But old habits die hard—many families still used kerosene lamps for years afterward.

    1947: The opening of the Dunton Quarry Mine brought jobs and helped bring the railroad closer to town. Mining became a vital part of the valley’s economy.

    1950s: The town began to grow. Guest ranches popped up, Hollywood stars visited to escape the city, and the community built more schools and shops. Lucerne Valley was no longer just a stopover — it was becoming a real town.

    1980s: Mitsubishi Cement Company bought the Cushenbury cement plant and became one of the area’s biggest employers, strengthening the region’s industrial ties.

    Present Day: Lucerne Valley remains a rural, tight-knit community with deep roots in desert history. People still appreciate open land, self-reliance, and the quiet rhythms of high desert life.

  • Big Bear, California

    Historical Timeline

    Pre-1800s: For over 2,000 years, the Serrano people lived in Big Bear Valley. They called themselves the Yuhaviatam, or “People of the Pines.” They thrived in the forests, gathering acorns, hunting deer and rabbits, and holding sacred ceremonies in the clear mountain air.

    1845: Benjamin Davis Wilson led a group into the San Bernardino Mountains searching for raiders. What they found instead were dozens of grizzly bears. Impressed and slightly alarmed, he named the place “Bear Valley” and called the marshy lake “Big Bear Lake.”

    1859: Prospector William F. Holcomb struck gold in the valley. That discovery kicked off a local gold rush, and Holcomb Valley quickly became the busiest settlement in San Bernardino County.

    1884: Entrepreneur Frank Brown built a dam in Bear Valley to store water for farms down in Redlands. The result was Big Bear Lake — at the time, the largest man-made lake in the world.

    1912: A second, taller dam was built to hold even more water. The original dam still sits submerged beneath today’s lake surface.

    1920s: As cars got better and roads improved, more people came up to Big Bear to escape the city. The cool air and pine forests made it a natural resort town. Hollywood even started filming westerns and outdoor scenes here.

    1921: Emile Jesserun opened the Pan Hot Springs Hotel, one of the first major resorts. People came to relax, breathe the fresh mountain air, and soak in the hot springs.

    1929: Big Bear got its first ski jump, setting the stage for winter sports. It was the beginning of Big Bear’s transformation into a year-round getaway.

    1952: Tommy Tyndall opened Snow Summit, one of the first full-scale ski resorts in the region. Skiing, snowboarding, and tubing became part of local life and a big draw for visitors.

    1968: Construction began on the Big Bear Solar Observatory, built right on the lake to take advantage of the clear skies and high elevation.

    1980: Big Bear Lake officially incorporated as a city on November 28, giving the mountain town its own local government and a clearer sense of identity.

    Present Day: Big Bear is a four-season destination — skiing and snowboarding in winter, boating and hiking in summer, fall colors, spring flowers, and crisp mountain air year-round. It remains a beloved mix of natural beauty, frontier history, and outdoor adventure.

  • Crestline, California

    Historical Timeline

    Pre-1800s: The Serrano people lived seasonally in the San Bernardino Mountains, including the Crestline area. They gathered acorns, hunted game, and held ceremonies in the forests, forming a deep connection to the land.

    1850s: Mormon settlers arrived and set up sawmills to harvest the rich pine forests. Logging became the first industry in the area and helped open up the mountains for future settlements.

    1906: A group of investors from San Bernardino bought 630 acres in the mountains. They saw the area’s potential as both a retreat and a resource — this marked the beginning of Crestline as a developed community.

    1926: Arthur Gregory Sr., a citrus grower from Redlands, built a sawmill in a spot called Valley of the Moon. He needed packing crates for his fruit business, and the mountains supplied both timber and cool air.

    1937–1939: Construction of Lake Gregory began with help from the Works Progress Administration. Gregory himself helped finance the project. Heavy rains filled the lake quickly, and it soon became the heart of the community — a place for swimming, fishing, and picnics.

    1946: Crestline became home to the world’s first church parish named after newly canonized Saint Frances Xavier Cabrini. The little church became a spiritual anchor in the mountains.

    1983: Hang gliders had been launching from the nearby cliffs for years, but in 1983, the San Bernardino Hang Gliding Association was renamed the Crestline Soaring Society. The skies above Crestline became a destination for gliders and paragliders alike.

    2003: The Old Fire swept across the San Bernardino Mountains, forcing evacuations in Crestline. It was a stark reminder of how quickly wildfire could threaten even the quietest mountain towns.

    2023: A record-setting blizzard buried Crestline in snow, leaving many residents trapped for days. Roads were blocked, supplies ran short, and neighbors leaned on each other while emergency crews worked around the clock to help.

    Present Day: Crestline is still a peaceful mountain town with tall pines, winding roads, and the cool waters of Lake Gregory. History, nature, and a strong sense of community continue to shape daily life.

  • Cajon Pass, California

    Historical Timeline

    Pre-1800s: Long before roads or railroads, the Serrano people traveled through Cajon Pass. It was a natural corridor between the Mojave Desert and the valleys to the south — a well-worn trail for trade, gathering, and seasonal movement.

    1776: Spanish explorers, including Father Francisco Garcés, came through the pass. It soon became part of what would later be called the Old Spanish Trail, linking New Mexico to California.

    1830: Trader Antonio Armijo officially led a commercial caravan through Cajon Pass, making it part of the main route for trade between Santa Fe and Los Angeles.

    1848: A few former members of the Mormon Battalion managed to get a wagon through the pass, proving that the steep, rocky route could support overland wagon travel.

    1861: John Brown Sr. built a toll road through Cajon Pass. It made travel easier for wagons and stagecoaches and became the main route connecting Southern California to the desert and beyond.

    1885: The California Southern Railroad completed its line through Cajon Pass, connecting San Bernardino to Barstow. Trains started hauling people, cattle, and freight through the mountains, transforming travel in the region.

    1916: The first paved highway over Cajon Pass was finished, opening the route to automobiles and marking the beginning of modern highway travel in the High Desert.

    1926: Route 66 officially included the road through Cajon Pass. This brought a wave of tourism, roadside businesses, and car culture to the area.

    1969: Interstate 15 was built through the pass, replacing the old highway and making travel faster and more reliable — though not immune to traffic jams and winter weather.

    1989: A tragic train accident occurred when a Southern Pacific freight train lost its brakes and derailed in the pass. The crash caused a deadly pipeline explosion and became one of the worst accidents in the region’s history.

    2016: The Blue Cut Fire tore through Cajon Pass, forcing evacuations and destroying homes. It spread quickly due to high winds and dry brush, reminding everyone just how dangerous fire season can be.

    Present Day: Cajon Pass remains one of the busiest mountain crossings in Southern California. Whether it’s semis on the freeway, Amtrak trains, or long freight hauls, the pass is still doing what it’s done for centuries — carrying people and goods across the mountains.

  • Wrightwood, California

    Historical Timeline

    Pre-1800s: The area that would become Wrightwood was home to the Serrano people, who called themselves the Yuharetum — “people of the pines.” They lived seasonally in the mountains, hunting game, gathering plants, and holding ceremonies in the forested canyons.

    1812: A powerful earthquake, believed to have started near Wrightwood, shook Southern California. The San Juan Capistrano quake damaged missions across the region and left a lasting mark on early California history.

    1854: Isaac Slover, one of the region’s earliest Anglo settlers and bear hunters, was killed by a grizzly near the Wrightwood area. This story added to the frontier reputation of the San Gabriel Mountains.

    1886: Sumner Wright moved to California and eventually discovered the beauty of the Swarthout Valley. He later bought land from prospector Samuel Guffy and started building what would become the town of Wrightwood.

    1924: Facing financial pressure, Sumner Wright subdivided his land into mountain lots and officially formed the village of Wrightwood. It quickly became a getaway for people looking for pine trees and fresh mountain air.

    1926: William Bristol built the Acorn Lodge. This rustic lodge became a social hub for visitors and gave Wrightwood a reputation as a relaxing mountain resort.

    1961: Wrightwood got its first cable TV service — a big deal for a small mountain town that had been pretty isolated for most of its early years.

    1967: The Southern California Gas Company brought natural gas to the area, making life more convenient for full-time residents and visitors alike.

    1970: The opening of Interstate 15 over Cajon Pass made it easier for folks in the Inland Empire and Los Angeles to reach Wrightwood, bringing in more weekenders and winter visitors.

    1973: The road to Crystal Lake reopened after years of closure, reconnecting Wrightwood with the rest of the San Gabriel range and improving access from the south.

    1976: Wrightwood got its first paramedic team — Chuck Blakeslee and Dave Faust — giving the community better emergency medical services in a remote mountain setting.

    2016: The Blue Cut Fire led to mandatory evacuations in Wrightwood. Flames threatened homes and forced thousands of High Desert residents to flee.

    2020: The Bobcat Fire burned through the San Gabriels, and Wrightwood was again on evacuation watch. Wildfire danger had become a growing concern.

    2024: The Bridge Fire hit close to home, forcing the entire town to evacuate. It was a stark reminder of mountain communities’ vulnerability to nature’s unpredictability.

    Present Day: Wrightwood remains a peaceful, pine-covered town in the San Gabriel Mountains. It’s known for skiing, hiking, small-town charm, and neighbors who look out for one another.

  • Adelanto, California

    Historical Timeline

    Pre-1915: Long before it was a city, the land around Adelanto was home to the Serrano people. They lived off the Mojave Desert’s natural resources and followed seasonal cycles along the riverbeds and mountains.

    1915: E.H. Richardson, who invented the Hotpoint electric iron, sold his patent and used the money to buy land in the High Desert. His dream was to build a planned community — a place where World War I veterans suffering from lung conditions could live and heal. He laid out one-acre plots with clean air and sunshine in mind.

    1917: The new settlement got a post office and the name “Adelanto,” which means “progress” in Spanish — a fitting name for a community built on new beginnings.

    1920s–1930s: Adelanto became known for its fruit orchards. Apples, pears, and cider were the pride of the town. But the Great Depression hit hard, and many orchards were torn out and replaced with chicken farms.

    Present Day: Adelanto is still growing and evolving. It’s a mix of military roots, farming history, and modern industry — with people from all walks of life calling it home under the big desert sky.

  • Phelan, California

    Historical Timeline

    1851: Mormon pioneers passed through what is now Phelan on their way to settle San Bernardino. They followed a rugged path across the desert, later known as the Mormon Trail.

    Late 1800s: As stagecoaches traveled between Los Angeles and Las Vegas, Phelan became a stopping point in the wide-open desert. A few ranches and scattered homes dotted the area, helping travelers refuel and rest.

    1916: A post office was established and officially became “Phelan.” It was named after Senator James D. Phelan and his brother John, who had ties to land in the area.

    2008: Residents voted to form the Phelan Piñon Hills Community Services District. This allowed locals to manage their water, parks, and street lighting — helping preserve the area’s quiet, rural character.

    Present Day: Phelan is still an unincorporated town, known for big skies, wide spaces, and a slower pace of life. Tucked between the San Gabriel Mountains and the Mojave Desert, it draws folks who appreciate open land and small-town values.

  • Victorville, California

    Historical Timeline

    Early 1900s: The name “Apple Valley” started appearing, possibly linked to the Appleton Land Company. Ursula M. Poates is sometimes credited with popularizing it.

    1920s: Apple orchards lined the riverbanks. The valley earned a reputation for producing crisp, sweet apples — for a time, it lived up to its name.

    1926: Nolie and Lela Murray opened Murray’s Dude Ranch — one of the few vacation spots in the West that welcomed Black guests during segregation.

    1930s: The orchards began to fade. The cost of irrigation and the harsh economy of the Great Depression made farming harder to sustain.

    1946: Newton T. Bass and Bernard “Bud” Westlund launched Apple Valley Ranchos, marketing the area as a sunny, relaxed alternative to city life.

    1948: The Apple Valley Inn opened on Thanksgiving Day. A swanky hotel, it was built to impress land buyers and draw in celebrities.

    1949: The first official post office opened, making the name “Apple Valley” permanent.

    1950s: Growth kicked into high gear. Schools, churches, banks, and a golf course popped up. Apple Valley became a small but thriving community.

    1965: Roy Rogers and Dale Evans moved to town. Roy leased the Apple Valley Inn and put his name on it, giving the town a little Hollywood sparkle.

    1967: The Roy Rogers-Dale Evans Museum opened, full of cowboy hats, saddles, and movie memorabilia. Fans flocked to see it.

    1976: The museum moved to nearby Victorville to reach more visitors.

    1988: Apple Valley became an official town on November 14. By then, over 41,000 people called it home.

    2003: The museum packed up again, this time heading to Branson, Missouri, chasing a bigger audience.

    2009: Sadly, the Branson museum closed. But the legacy of Roy and Dale still lives on in Apple Valley.

    Present Day: Apple Valley continues to grow, with new homes and businesses rising up where orchards once stood. But it still holds onto its Western roots, desert charm, and small-town spirit.

  • Lake Thompson

    The Vanished Ice Age Lake Beneath Antelope Valley

    Long before the roar of jet engines echoed from Edwards Air Force Base and the Antelope Valley became known for aerospace and arid winds, it was home to a massive Ice Age lake—Lake Thompson. This now-vanished body of water tells a deep story about climate, earth movements, and the life that once thrived in a very different Mojave.

    A Desert That Was Once a Basin of Water

    Lake Thompson formed during the late Pleistocene epoch, when glaciers covered parts of North America and climates across the West were colder and wetter. The Antelope Valley, surrounded by the San Gabriel, San Bernardino, and Tehachapi mountains, collected snowmelt and rainwater in a broad, low-lying depression. Back then, this area was a “closed basin”—a natural bowl with no outlet to the sea. So, as precipitation increased and evaporation stayed low, water began to rise and pool, eventually forming a lake roughly 367 square miles in size.

    At its fullest, Lake Thompson was nearly 230 feet deep and stretched across Rogers Lake, Rosamond Lake, and Buckhorn Lake. These are the dry, cracked lakebeds we see today—remnants of that long-lost water body.

    A Sedimentary Record of Changing Times

    The floor of Lake Thompson became a repository for everything the surrounding land and water brought in: silt, clay, sand, and organic matter. These sediments settled in quiet layers, building up year after year. Over time, these layers became a rich record of the lake’s rise and fall.

    Core samples taken from the basin tell the story. Some show fine clays deposited during long, deep lake periods, while others reveal coarser, sandy material left behind as the lake dried out during warmer interludes. Layers of carbonate crust—deposited when water levels fell and minerals became concentrated—mark periods of evaporation and shrinking shorelines. Organic material embedded in these layers has been radiocarbon dated to track climate shifts over the last 30,000 years.

    Shaped by Faults, Not Just Floods

    The creation of Lake Thompson wasn’t just about water. It was also about land and how it moved. The Antelope Valley sits along major tectonic features: the San Andreas Fault to the south and the Garlock Fault to the north. Movements along these faults shaped the land over millions of years, causing earth blocks to shift and drop, forming depressions that trapped water.

    These tectonic movements, combined with subsidence (the gradual sinking of the Earth’s surface), created the basin where Lake Thompson formed. The region’s geology continues to shift today, though the Big Ice Age lakes era has passed.

    Fossils and Evidence of a Living Landscape

    Lake Thompson didn’t just collect water—it supported life, lots of it. Fossil finds in the lake’s ancient sediments include bones from mammoths, extinct camels, horses, and bison—megafauna that roamed the lake’s edges during the Ice Age. Their presence tells us this was not a lifeless salt flat but a rich, green wetland environment teeming with grasslands and water sources.

    Tiny fossils matter too. Shells from freshwater snails, fish bones, and ostracods (tiny crustaceans) help scientists reconstruct the lake’s ecosystem. These fossils point to freshwater conditions during much of the lake’s life, followed by increasingly salty and alkaline phases as it dried out.

    A Lake Fades Into Memory

    By around 8,000 years ago, Lake Thompson had mostly dried up. The shift into the warmer, drier Holocene epoch reduced rainfall, boosted evaporation, and turned wetlands into playas. What was once a vibrant Ice Age lake became the flat, empty spaces we see today—windblown, sunbaked, and often forgotten.

    Today, the legacy of Lake Thompson is still visible if you know where to look. Rogers and Rosamond dry lakes, now used for aircraft and rocket testing, still bear the perfectly flat imprint of deep water long gone. The ancient shorelines are marked in subtle terraces along the valley’s edges. Sediment layers hold secrets of shifting climates, and buried bones remind us that this was once a much wilder place.


    Conclusion: A Geologic Memory Written in Dry Earth

    Lake Thompson isn’t just a vanished lake. It shows how Earth’s climate, geography, and ecosystems work together. It’s a story about how even a desert was once a haven for giant beasts and flowing water. And though the lake is gone, its imprint—etched into the land and buried in the soil—remains evidence for all who want to read the story of California’s ancient inland sea.
