Inyo County History
From the irrigated gardens of the Owens Valley Paiute to the highest and lowest ground in the lower 48 — and the water war that reshaped California — Inyo County holds more extremes per mile than anywhere in the American West.
A Brief History of Inyo County
Inyo County was established in 1866, assembled from territory of Mono and Tulare counties as mining and ranching pushed up the Owens Valley. Its name is drawn from a Paiute word often translated as “dwelling place of a great spirit.”
Long before the county lines, the Nüümü — the Owens Valley Paiute — engineered one of the great surprises of Native California: an extensive network of irrigation ditches that spread the valley’s streams over wild seed fields, sustaining villages from Owens Lake to Bishop Creek. Settlers arrived in 1861, Fort Independence rose in 1862, and the Owens Valley Indian War (1862–65) reshaped life in the valley forever.
Silver made the county boom: Cerro Gordo, high above Owens Lake, became California’s greatest silver camp in the 1870s, its ore freighted down the mountain and shipped south — wealth that helped build the young city of Los Angeles. In 1872, the Lone Pine earthquake, one of the largest in U.S. history, leveled the county’s settlements in seconds.
Then came the water. In 1913, Los Angeles completed its 233-mile aqueduct down the Owens Valley; by the mid-1920s Owens Lake was a dust bowl and the infamous California water wars had begun — complete with dynamited spillways and national headlines. During World War II, more than 10,000 Japanese Americans were incarcerated at Manzanar, north of Independence, a story now preserved as a National Historic Site.
Today Inyo County holds both extremes of the lower 48 — Mt. Whitney at 14,505 feet and Badwater Basin at 282 feet below sea level — the world’s oldest living trees, and a landscape that has filled hundreds of movies.
Key Moments
The Nüümü
Owens Valley Paiute communities irrigate wild seed fields with an ingenious network of ditches, sustaining villages along the valley floor and up into the canyons.
Settlers Arrive at Bishop Creek
Samuel Addison Bishop drives a cattle operation into the valley; the settlement that grows around his ranch becomes today’s Bishop.
Fort Independence
The U.S. Army establishes Fort Independence; escalating conflict between settlers and the Nüümü becomes the Owens Valley Indian War, which smolders until 1865.
Inyo County Established
The new county is assembled from Mono and Tulare territory, with Independence as its seat — named for a Paiute word meaning “dwelling place of a great spirit.”
Silver at Cerro Gordo
Mortimer Belshaw’s Union Mine turns the peak above Owens Lake into California’s greatest silver camp, with ore freighted across the lake toward Los Angeles.
The Lone Pine Earthquake
One of the largest earthquakes in U.S. history flattens Lone Pine in seconds, claiming more than two dozen lives and reshaping the valley’s settlements.
First Ascent of Mt. Whitney
Charles Begole, A.H. Johnson, and John Lucas of Lone Pine reach the summit of the highest peak in the contiguous United States.
The Land of Little Rain
Independence writer Mary Hunter Austin publishes her desert masterpiece, giving the valley one of its defining voices.
The Aqueduct Arrives
Los Angeles completes its 233-mile aqueduct down the Owens Valley; within a dozen years Owens Lake is nearly dry and the “water wars” become a national story.
The Alabama Gates
Valley farmers seize the aqueduct’s spillgates in protest, dynamite strikes the pipeline, and Los Angeles keeps buying land and water rights.
Manzanar
More than 10,000 Japanese Americans — most of them U.S. citizens — are incarcerated at the Manzanar War Relocation Center north of Independence.
Legends & Notable Figures
The prospectors, chroniclers, engineers, and outlaws whose lives shaped the county's story
The Nüümü Irrigators
Long before settlers arrived, Owens Valley Paiute communities built and tended an extensive network of irrigation ditches, spreading spring floods across wild seed fields. Early visitors found the system so sophisticated they assumed a “lost civilization” must have built it.
Mary Hunter Austin
Austin made her home in Independence and the desert her subject. The Land of Little Rain (1903) captured the Owens Valley on the eve of the aqueduct and remains a classic of American nature writing.
Mortimer Belshaw
Belshaw took control of Cerro Gordo’s rich Union Mine, cut a toll road down the mountain to his Swansea smelters, and shipped silver by the ton across Owens Lake — wealth that helped raise the young city of Los Angeles.
William Mulholland
The Irish-born chief engineer who built the 233-mile Los Angeles Aqueduct and, in doing so, drained the valley. A visionary to the city he supplied — and a villain to generations of Owens Valley residents.
Death Valley Scotty
Prospector, performer, and magnificent storyteller, Walter Scott charmed a Chicago millionaire into building a castle in the desert. Scotty’s Castle still anchors the northern end of Death Valley — with a tall tale for every room.
The Death Valley ’49ers
Lost emigrants wandered into the worst place the West could offer. William Lewis Manly and John Rogers walked hundreds of miles for rescue supplies and led the families out — leaving behind only a name: “Goodbye, Death Valley.”
