100 free Wyoming trivia questions with answers — geography quiz, new questions added Aug 2026.
60 free Wyoming trivia questions with answers. Wyoming has the fewest people of any state and more than its share of firsts: the first national park, the first national monument, the first women voters, jurors and governor. This quiz covers the Cowboy State in 100 questions, from Old Faithful and the Grand Teton to the Oregon Trail, Fort Laramie, the Johnson County War, Butch Cassidy's prison stretch and the Teapot Dome scandal. You will also get the things locals argue about: why Casper is misspelled, which tribes share the Wind River Reservation, where the coal comes from, what the bucking horse on the licence plate is called, and where Brokeback Mountain was really filmed. The early questions suit anyone who has driven through on I-80; the later ones will only be answered by people who know their trona from their bentonite. Every answer has been checked against a documented source and each question shows its citation and a short explanation after you answer.
