The Sonoran Desert stretches from southern California and Arizona down to Mexico, to include most of the Baja and half of the Mexican state that shares the desert's name. This unique living museum nestled in the Tucson Mountain basin, at the foot of Saguaro National Monument West, opened in 1952 and has been steadily expanding and improving ever since.
All exhibits are wheelchair accessible.
Fossils of the giant reptile, plus artist renderings and a chance to dig for replica fossils, bring some of the excitement of this 1994 discovery home, particularly for school groups and families with children. The museum is open every day of the year, with extended Saturday night hours June through September. Take Speedway Boulevard west over Gates Pass, veering right on Kinney Road. The museum is on the left. There's truly nothing else like it, anywhere.
