We are reaching Picacho over an 18mile dirt road. It is a bit rough with corrugated stretches. The first part is crossing a high plateau before it descends into a valley surrounded by impressive volcanic rock formations.

Picacho, California was once a thriving gold mining town established in 1862 after Jose Maria Maville’s discovery near Picacho Peak. You’ll find this ghost town 25 miles north of Yuma, where nearly 2,500 residents once lived during its 1870s-1900s heyday. The community declined after 1910 when the Laguna Dam eliminated essential steamboat transportation and ore quality diminished. Today, you can explore remaining mill ruins and relocated graves that tell stories of frontier resilience.
Desert prospectors worked sun-baked washes using ancient techniques to separate fine gold from sand in this harsh landscape.
You can still see evidence of these early efforts in the small tailings piles scattered throughout the region. The settlement, originally named Rio before becoming Picacho, formed around these mining activities.
The early mining techniques were basic but effective for the very fine gold particles typical of these desert placer deposits. The gold deposits in the Picacho Mining District consisted primarily of thin gold-bearing stringers in schist formations. By 1872, operations expanded substantially into hard rock quarrying, marking a new era in the mine’s development.
Golden Years: Peak Population and Prosperity
Picacho’s golden era transformed the once-modest mining camp into a thriving community of approximately 2,500 residents between the 1870s and early 1900s, establishing it as one of the largest settlements in this remote corner of Southern California.
Community dynamics evolved beyond mere survival to include social institutions—a school educating 90 children, multiple saloons, and even a polo field where residents could escape the rigors of daily life.
The economic backbone consisted of approximately 700 miners extracting precious ore that yielded 96,750 ounces between 1906-1910 alone.

Despite low ore grades averaging just 0.15 ounces per ton, the operation generated approximately $2,000,000 during peak years.Economic fluctuations followed mining cycles, with periodic investments and technological improvements temporarily reversing declining production trends. The town proudly claimed the distinction of being the first registered town in Imperial County when it was officially named Picacho in 1895.
The upper stamp mill, constructed in 1886 by Stephen A. Dorsey, produced an impressive 13 million dollars in gold before operations ceased in 1910.
The decline of Picacho
The story of Picacho’s decline begins around 1910, when a storm of economic and infrastructure challenges overwhelmed the once-thriving mining community.
The economic impact was swift and devastating as gold ore quality diminished considerably, making mining operations unprofitable.
The timeline of community disintegration unfolded in clear stages:Laguna Dam’s 1910 completion severed crucial steamboat transportation, dramatically increasing freight costs.
Mining operations ceased entirely by 1910 as costs soared and ore quality plummeted.
Population rapidly declined as employment disappeared and businesses shuttered.
Imperial Dam’s 1938 construction raised water levels by 20 feet, submerging much of the original townsite.
Like many ghost towns across the American West, Picacho’s story reflects the boom-and-bust cycle tied to resource exploitation and changing transportation networks.
Today, you’ll find only scattered stone ruins where 700 miners once lived, their history gradually erased by the engineered landscape that now defines Picacho State Recreation Area.
Relocated Graves, Preserved Stories
As rising waters from the Imperial Dam project threatened to consume Picacho’s history beneath the Colorado River in 1938, authorities undertook the solemn task of relocating the town’s cemetery from its original riverside location.
The relocated stories of Picacho’s pioneers now rest beside the state park campground, where twelve additional bodies from Castle Dome Landing joined them. Despite preservation efforts, most graves remain unmarked—their headstones lost during the hasty shift, creating gaps in historical documentation.
Though white fencing now protects these preserved memories near the ravine, the environmental displacement fundamentally altered the connection between Picacho’s dead and the land they once inhabited.
Today, you’ll find this historical cemetery juxtaposed against recreational facilities, a physical reminder of how water infrastructure development forever changed the landscape of the American Southwest.
What Remains: The Ghost Town Today
Today’s visitors to Picacho encounter a ghost town dramatically altered by time and environmental change, yet still revealing fascinating remnants of its gold mining heyday.
The historical significance of these ruins provides a window into California’s vibrant mining past, while archaeological findings continue to document the settlement’s evolution.
When exploring the area, you’ll discover:Two historic mills standing as primary architectural evidence, including visible stone walls and wooden poles from Dorsey’s original mill
The relocated town cemetery with its few marked graves, including Thomas Rochester’s notable memorial
