60 free Grand Teton National Park trivia questions with answers — geography quiz, new questions added Aug 2026.
This Grand Teton National Park trivia quiz covers the 310,000-acre Wyoming park where the Teton Range shoots 7,000 feet straight up from the floor of Jackson Hole with no foothills in between. It ranges across the peaks and glaciers, the string of moraine lakes at the foot of the range, the Snake River and its native cutthroat trout, and the elk, moose, pronghorn, bears and wolves that make it one of the richest wildlife parks in the lower 48. The history questions dig into the fur trappers who named the Tetons, the disputed 1872 and 1898 first ascents, Calvin Coolidge's 1929 park, John D. Rockefeller Jr.'s covert land purchases and the bitterly opposed 1943 national monument, plus Mormon Row, Menor's Ferry, the Chapel of the Transfiguration, the film Shane, the Federal Reserve's summer retreat and the only commercial airport inside a US national park. Difficulty runs from easy to expert and is marked on every question, so it works for a road-trip game or a hardcore park-nerd challenge. Every answer was checked against Wikipedia and each question carries its citation. If you enjoy it, try our Yellowstone and US National Parks quizzes next.
