Another prominent Yellowstone landmark, the Roosevelt Arch, was constructed in 1903 under the supervision of Chittenden. A north entrance station and gate near Gardiner, Montana, was first suggested by Captains Wilber Wilder and Oscar Brown in 1899. However it was not until 1903 that Chittenden and then-Acting Superintendent Major John Pitcher were able to gain approval for the arch. The ground breaking for the arch coincided with the two-week vacation visit of U.S. President Theodore Roosevelt to the park. Roosevelt was the only U.S. President to visit Yellowstone during the army era. On his last day in the park, April 24, 1903, Roosevelt participated in the cornerstone laying ceremony and the arch was completed later that year. In 1904, Major John Pitcher recommended the construction of several new buildings to accommodate the growing contingent of soldiers. The only structure approved was the new post exchange located just south of the double cavalry barracks. This striking Colonial Revival styled structure was completed in 1905, replacing a much smaller post exchange that had been built in 1894. It now functions as the National Park Service canteen.
