FORT HUACHUCA, Cochise County, Arizona - Old office building: Many of the old buildings in the Old Post area are constructed of stone. - Widowed Support Center: This stone building is not on Old Post. It is the Widowed Support Center located near the Main Gate. - Leonard Wood Hall: Leonard Wood was a surgeon at Fort Huachuca in the mid-1880s and this building was originally the post hospital. When this photo was taken, the building was in use as the military finance office. - Brown Parade Field 1: The historic Army barracks in this photo were constructed in 1883. They are still in use as office space. The Huachuca Mountains are in the background. - Brown Parade Field 2: Another view of the historic Army barracks constructed in 1883. The Whetstone Mountains are in the far distance. - Model wagon display: There is one room in the Fort Huachuca Historical Museum with several displays of detailed models of Army wagons. These two are a four mule escort wagon (left) and a medical corps ambulance. The mirrored background on the displays make the photographs look like double exposures. - Smiling Jammer: This one is on display in the U.S. Army Intelligence Museum, a different museum on Fort Huachuca. "Smiling Jammer" is my name for this device. The sign above it reads, "Jammers, like this barrage jammer, were used in tactical situations to distort enemy communications with noise and disrupt their command and control. But jamming was seldom used because the enemy turned on their radios infrequently and battles were brief." - Lie Detector: This early lie detector is also on display in the U.S. Army Intelligence Museum. The sign above it reads, "Unlike the polygraph, which measures changes in blood pressure, breathing, and skin response, this early version of the lie detector depended on only Galvanic Skin Response, or perspiration. The Counter Intelligence Corps began using polygraphs around 1948." - Senior officer housing: "e;Officers Row"e; is part of the Old Post area that is designated a National Historic Landmark. - Old Post scenic 1: This view overlooking Old Post was taken from Reservoir Hill, looking northwest to the Mustang Mountains (left) and Whetstone Mountains (right). - Old Post scenic 2: This photo was also taken from Reservoir Hill, looking up Huachuca Canyon. - Garden Canyon 1: A light dusting of snow remains in this view from a Garden Canyon picnic area. - Mountains in summer: Those are the Huachuca Mountains, looking southwest from the old Splinter Village area of post. - Spring sunrise at Main Gate: Light snow and low clouds turn pink at sunrise. Looking west approaching the main gate.
