Moab Museum, long associated with the Dan O'Laurie name, is the town's main local-history museum. It helps connect the surrounding red-rock drama to human stories: Indigenous presence, uranium mining, ranching, dinosaurs, and the shift toward recreation tourism.
It is a smart first-day stop if you want Moab to be more than a base for Arches and Canyonlands. The museum is compact, but it gives useful context before you head out into the landscape.
