This Arizona trivia quiz has 70 free questions with answers and covers the whole state: how it got its name and its Valentine's Day statehood, the territorial capitals before Phoenix, the Gadsden Purchase, Geronimo and the Gunfight at the O.K. Corral, and the natural landmarks everyone has seen in photos, from the Grand Canyon and Monument Valley to Antelope Canyon, Havasu Falls and Meteor Crater. There are questions on the state symbols (the bird, the tree, the neckwear and the surprisingly recent state planet), on why most of Arizona never changes its clocks, on the London Bridge that ended up in Lake Havasu City, and on sports, from the Diamondbacks' 2001 World Series to spring training and the Coyotes' departure. Famous Arizonans such as Barry Goldwater, Sandra Day O'Connor, John McCain and Cesar Chavez appear too. It works for a family road trip, a classroom, or a trivia night. Every answer has been checked against Wikipedia or a primary source, and each question links to the page that confirms it.
