Constructed in 1929 and named after General Alexander M. Tuthill, Fort Tuthill was considered one of the finest National Guard training facilities in the United States. Located three miles south of Flagstaff, Arizona, this permanent facility served as the annual field-training site for the 158th Infantry Regiment Arizona National Guard from 1929 to 1937, again in 1939, and for the last time in 1948.

Housed in two of Fort Tuthill’s original buildings, the Fort Tuthill Military Museum presents the appearance of a Regimental Headquarters Building of the 1940's. The Museum Mission is to preserve and present the distinguished history and traditions of the 158th Infantry Regiment, 158th Regimental Combat Team, and current 1st Battalion 158th Infantry Arizona National Guard. Exhibits trace the history of the regiment from it's organization in 1865 as the 1st Regiment Arizona Volunteers to 1967 retirement of the Regimental Colors and 2005 organization and Afghanistan deployment of 1st Battalion 158th Infantry.
