The sentry post was built in 1904 during the height of statewide labor disturbances, when the Western Federation of Miners was managing legal strikes in the San Juan district, Cripple Creek district, Colorado City, and other areas of the West. The Fort Peabody site encompasses the ridge above and southeast of the Imogene Pass road summit, spanning approximately 413 feet northwest to southeast on the lower ridge of Telluride Peak. It was a Colorado National Guard sentry post that included a small guardhouse, a flag mount and what some characterized as a sniper's nest. Until 2010, the site consisted of the remains of a 6' x 8' wood-frame building enclosed in stone walls, a large stone mound, a 5' x 6' depression, and a small pile of rocks all on the ridge top, along with a stone enclosure down the ridge to the northwest, identified as the "sniper nest" or "machine gun nest." In 2010 Fort Peabody was stabilized and restored under the direction of the San Miguel County Open Space and Recreation office and the USDA Forest Service as directed by the National Historic Preservation Act.
