Colorado River State Historic Park
On the other side of the river from Fort Yuma, the Civil War–period quartermaster depot resupplied army posts to the north and east and served as a distribution point for steamboat freight headed overland to Arizona forts. The 1853 home of riverboat captain G. A. Johnson is the depot's earliest building and the centerpiece of this park. The residence also served as a weather bureau and home for customs agents, among other functions, and the self-guided tour through the house provides a complete history. Also on display are antique surreys and more "modern" modes of transportation like a 1931 Model A Ford pickup. You can visit a re-creation of the Commanding Officer's Quarters, complete with period furnishings. The Yuma Visitor Center and a pie shop are also here.
