RIO LOBO Ranch is a family owned ranch located in Edwards County, near Camp Wood, Texas. Camp Wood is on the Nueces River near the site of the present-day town of Camp Wood in far southwestern Real County. It was established as a United States military outpost on May 20, 1857, when it was occupied by Lt. E. D. Philips and a company of the First Infantry assigned to protect the San Antonio-El Paso route and the Rio Grande valley from Indian raids. The camp was located near the ruins of San Lorenzo de la Santa Cruz Mission; its water was supplied by the same spring that had earlier served the mission and that later provided water for the town of Camp Wood. The installation was named for Bvt. Maj. George W. F. Wood.
