At the end of the Apache Wars, the protection of Fort Huachuca and the completion of the Southern Pacific and the El Paso & Southwestern railroads, the San Pedro Valley began to populate. Oliver Fry and his two oldest sons traveled from Texas on the railroad and settled on 320 acres (1.3 km2) just outside of Fort Huachuca around 1901.
The first business that opened just outside the east gate of Fort Huachuca was a saloon and house of ill repute owned by John and Ellen Reilly opened in 1892. In 1911, Margaret Carmichael bought the Reilly homestead and business. By 1913, Margaret Carmichael had leased the business back to the Reillys. Also, in 1913, a group of dry land farmers settled in the local area and named their settlement Buena. Buena was located east of Garden Canyon on a railroad whistle-stop between Lewis Springs and Fort Huachuca. At this site was a post office and a schoolhouse that served children in Buena, Garden Canyon and outreaches of the local area. Description by mapquest.com.
