Arizona Territory’s infamous prison (1876–1909) on a bluff above the Colorado River in Yuma. Stone and adobe cellblocks, the main gate, guard tower, and museum interpret the 3,000+ inmates once held here; later used as a high school and city shelter. Adjacent Quartermaster Depot / Yuma Crossing history rounds out a compact Colorado River desert stop.
