You’ll discover five remarkable ghost towns near Yuma that chronicle Arizona’s mining heritage. Castle Dome, worked from the 1600s until 1979, produced 200,000 ounces of silver and once housed 3,000 residents. Gila City’s 1858 placer rush attracted 1,200 miners before flooding destroyed it by 1862. The Kofa District’s King of Arizona mine extracted 227,500 ounces of gold, while Fortuna recovered 124,000 ounces before closing in 1926. Castle Dome Landing served as an essential steamboat port breaking Yuma’s river commerce monopoly. Each site offers unique insights into the region’s boom-and-bust cycles.

Castle Dome: Arizona’s Longest-Worked Mining District
When Spanish prospectors first scratched silver ore from the slopes near Castle Dome in the 1600s, they couldn’t have known they were opening Arizona’s longest-worked mining district—one that would sustain commercial operations for more than three centuries.
The mining history intensified in 1864 when high-grade silver galena attracted major investment from New York and San Francisco. By 1878, you’d find operations had already extracted 200,000 ounces of silver from 5,000 tons of ore. At its peak, the boomtown housed 3,000 residents who relied on the district’s 300+ mines—including Castle Dome, La Fortuna, and Flora Temple—for their livelihoods.
Silver production continued through two World Wars, driven by lead demand for ammunition manufacture. Castle Dome became the 2nd patented mining claim in Arizona, cementing its status as a cornerstone of territorial mining operations. The district employed thousands until 1979, when plummeting silver prices finally made processing costs unsustainable, ending Arizona’s most enduring mining operation.
Castle Dome Landing: Colorado River Steamboat Port
While Spanish prospectors launched the Castle Dome district‘s mining legacy, its commercial success depended on a parallel development forty to sixty miles west: Castle Dome Landing, established in 1863–1864 as a strategic steamboat port on the lower Colorado River.
You’ll find this landing broke Yuma’s monopoly on river commerce, serving as a critical transfer point where stern-wheel steamboats like the *Gila* offloaded mining supplies, equipment, and provisions onto wagons bound for interior camps.
Steamboat operations here moved up to 100 tons of cargo per voyage, carrying inbound merchandise and outbound silver-lead ore. Seasonal water levels and shifting sandbars demanded experienced pilots and light-draft vessels. The steamboats primarily operated during daylight hours to avoid the river’s numerous hazards and treacherous conditions. Colorado River steamboat service connected ports across Mexico and the United States, including settlements in California, Nevada, and Arizona.
Gila City: The Short-Lived Placer Gold Boom
Forty miles upstream from Castle Dome Landing, September 1858 brought Arizona’s first major placer rush when Colonel Jacob Snively’s discovery party panned visible nuggets from Monitor Gulch gravels on the north end of the Gila Mountains.
You’ll find Gila City’s remains about thirteen miles east of Yuma near present-day Dome, where 1,200 fortune-seekers once worked pay gravels yielding $30–$215 daily.
The boomtown featured saloons, monte tables, and Wells Fargo shipments of nuggets reaching twenty-two ounces, yet lacked both church and jail.
Shallow deposits enabled rapid extraction—and swift exhaustion.
Gold-bearing gravels extended along a three-mile stretch, with most productive mining concentrated around Monitor Gulch approximately a mile and a half west of Dome.
By 1862, miners dispersed to La Paz’s newer strikes while a devastating Gila River flood destroyed remaining structures.
The settlement gained official post office status by December 24, 1858, marking its brief moment as a recognized community.
Within a decade, this ghost town vanished into the desert.
Kofa Mining District and the King of Arizona Mine
Deep in the Kofa Mountains of northeastern Yuma County, Charles E. Eichelberger discovered the Kofa veins in 1896, launching a district that would produce over 227,500 ounces of gold.
The King of Arizona mine—lending its abbreviated name “Kofa” to the entire district—yielded surface ore worth $2,000 per ton. You’ll find mining history records showing a 225-ton cyanide mill operated here from 1899 until closure around 1910, when declining grades ended the bonanza.
The camp swelled to several hundred residents, with miners, Mexican woodcutters, and Chinese cooks enduring chronic water shortages in the desert east of the Colorado River. The community included approximately 100 houses, most constructed as tent structures to accommodate the rapidly growing population. The diverse immigrant workforce supported peak employment exceeding 100 men at the mine’s height.
Though a 1918 reopening attempt failed, the district’s legacy remains—$1.1 million in historic bullion production before the post office closed in 1928.
Fortuna Mine and Other Vanished Desert Camps
About 35 miles southeast of the Kofa district, prospectors struck another rich gold vein in the Gila Mountains during 1894–1895, igniting a rush that would build Fortuna into one of Yuma County’s most substantial desert mining towns.
By 1896, La Fortuna Gold Mining and Milling Company began extracting gold-bearing quartz through underground shafts and drifts, ultimately recovering roughly 124,000 ounces before exhaustion around 1926.
Fortuna history reveals impressive engineering: a 14-mile pipeline pumped 500 gallons per minute from the Gila River to feed a 20-stamp mill, cyanide plant, and the town’s hundreds of residents.
Mining techniques evolved from high-grade vein stoping to pillar recovery as ore dwindled.
The post office closed in 1904, and by 1915 Fortuna stood empty—another desert monument to boom-and-bust freedom. The Fortuna graveyard stands as a stark reminder of the dangerous working conditions and inevitable accidents that claimed the lives of miners, including Lesie Don, son of Judge Fletcher Morris Don. Today the former mine site lies within a military reservation, part of Luke Air Force Base Bombing Range since 1959, making access impossible without military authorization.
