Dust, Gold and Grit
It’s difficult to imagine an economy without credit cards, checks, or even enough coinage to make routine purchases. In truth, daily purchases were typically the domain of the very wealthy. But in Yuma’s early days, gold was the primary driver of the local economy. Much of the lifeblood for local merchants came from supplying nearby mines—most notably the North Star Mine and the Castle Dome Mine, each supporting populations of several thousand.
The 1848 California Gold Rush at Sutter’s Mill sparked a wave of treasure hunters heading west. Ironically, this migration had an inverse but significant impact on Yuma. A large number of these soon-to-be prospectors passed directly through Yuma Crossing. At the time, a rope ferry—located between what we now call Prison Hill and the Indian Mission across the Colorado River—allowed travelers, livestock, and supplies to cross the river.

How Yuma’s Rope Ferry Became a Gold Rush Goldmine
Reports from the era estimate that the rope ferry generated as much as $60,000 per month—equivalent to approximately $2.5 million in 2025. Each crossing came with a fee: 50 cents, 75 cents, or a dollar, depending on the load. With thousands passing through and animals in tow, the charges added up quickly and lucratively. Demand for food and livestock to feed the masses only increased as the Gold Rush intensified.
Interestingly, while these fortune seekers rushed toward Sutter’s Mill, they passed directly by untapped gold deposits nestled in the mountains surrounding Yuma. Eventually, prospectors began to recognize the value of the local terrain and turned their efforts to mining in the Yuma area.

From Gold Dust to Fields: Yuma’s Economic Transformation
Local merchants, eager to support these new endeavors, often offered credit or “grubstakes” to miners. For the right promise, one could secure a jackass, pickaxe, shovel, pan, skillet, and supplies like beans, bacon, and flour—all in hopes of finding feast or fortune.
One key figure in this era was E.F. Sanguinetti, a gold broker for the U.S. Government and a trusted local businessman. It was said that Sanguinetti could identify the origin of gold nuggets—down to the specific mountain range—just by examining their characteristics.
As gold mining began to wane, a new chapter opened. The Reclamation Act of 1902 ushered in an era of sustainable agriculture, allowing Yuma County to transform from a mining economy to an agricultural powerhouse.
But that, as they say, is a story for another time.
