A mansion finished in 1913 that was the home of John Benjamin Kendrick (1857–1933). Kendrick was a cattle rancher who served as governor of Wyoming before being elected to three terms as a United States senator. Trail End is now a state-operated museum and is known locally as the Kendrick Mansion. Most of the contents of the museum are original to the Kendrick family. The mansion and carriage house were designed by Glenn Charles McAlister, a self-taught architect from Billings, Montana. In 1979 the mansion's carriage house was converted into a small theater for the performing arts, dubbed The Carriage House Theater.
