Around 1879 the Llano Cattle Company acquired approximately 120 square miles (310 km2) in Garza County, including the land on which Camp Post is now situated. In 1883 they moved their ranch headquarters to the current site of Camp Post. A two-story frame house was built and a well was dug, this being the first hand-dug well in Garza County. The old well site is still visible today, and is located just south of Pioneer road, about halfway between the trading post and the swimming pool. The original wooden curb burned in 1937 and has been replaced by a replica.
