(Quercus gambelii )
Named after the American naturalist William Gambel (1823–1849), there are some 54 of these trees on campus. Although its wood is hard and dense, its branches are irregular and crooked, making them flexible enough to bend without breaking when covered with heavy snow. The bark is rough and brownish-gray. The leaves are generally 3 to 5 inches long, turning orange and yellow during autumn.
