The Cañada del Oro has been a consistant source of gold and mineral ore.  The Spanish name Cañon de Oro means the “Canyon of Gold.” This golden gulch sparked the Tucson gold rush in the mid-1850s. At different times, the creek was also called Canyon del Oro and Gold Canyon Creek. 
After rare summer and winter storms, the runoff flows out of the Santa Catalina Mountains from the north, runs past historic properties at the delta and turns to the south past ancient Indian ruins in the Catalina State Park.
After the Cañada del Oro drains out the Santa Catalina Mountains, it empties into the Tucson valley, eventually joining the Santa Cruz River near Tucson and Marana at the I-10 Interstate. When it flowed regularly, it was a reliable source of life for both animals and humans. Mountain runoff still helps supply drinking water for northwest Tucson residents today. 
Sightings of free flowing gold and other mineral veins stimulated most of the early American mining activity in this area.
The Cañada del Oro has long history of Indian aggressions and gold discoveries. This was the first area of the Santa Catalina Mountains reported to contain valuable minerals.
Even before American settlers began to arrive in Southern Arizona in the mid-1850s, they read newspaper stories about the Canyon of Gold near Tucson. As the Mexicans and Spanish explorers before them, prospectors found free flowing gold along the river and embedded in quartz veins. The hostile Apache Indians would repel many of those efforts to prospect for gold or to even pass through the area.
Yet, tales about a sealed off lost gold mine, an abandoned mission with a hidden cache of buried treasure, and naturally occurring gold deposits, still drove the bravest into the hills.
According to the legends, that mine, and the mission, may still be somewhere near the Cañada del Oro.

 Mining claims in the Cañada del Oro date back into the 1870s, but prospecting had been conducted for centuries.
