Fort Tyson, Military fort in La Paz County, Arizona.

Fort Tyson is a privately built fort from 1856 whose remains stand at the corner of Main Street and Moon Mountain Road in Quartzsite, Arizona. Charles Tyson raised it to shelter local miners and the water supply from raids by the Yavapai, also called Mohave-Apache. The surrounding settlement took the fort's name.

Charles Tyson built the fort in 1856 to protect miners in the region and secure access to water sources. The site played a role in the early phase of American westward expansion and the conflicts that defined that era.

The fort was built in response to raids by the Yavapai, also called Mohave-Apache, who resented settlers arriving on their land. The settlement took the fort's name, and later the town was renamed Quartzsite for the quartz found in the surrounding hills.

The site is open to visitors and can be explored on foot year-round. Informational markers on location explain the history and help visitors understand the remaining structures.

The well Tyson dug by hand in 1864 gave the settlement the name Tyson's Well, and a historical marker now stands where it was supposedly dug. The stage station he built in 1866 still stands at 161 West Main Street and houses the Quartzsite Museum and Historical Society.
