José Victor García acquired part of the land comprising this ranch in 1882 and transferred it to his son Celestino in 1887. The eastern part of the ranch was settled by another son, Lafayette García. Both José Victor and Celestino were active in Colorado politics and served in the state legislature. After Celestino’s death in 1925, his family sold the ranch to Francisco A. Espinosa, who was active in politics and in the Sociedad Protección Mutua de Trabjadores Unidos (SPMDTU), a Hispano fraternal and civil rights organization. Over the years, the ranch has produced sheep, cattle, hay, peas, and potatoes. Cattle are still raised on the ranch and hay is cut in the surrounding fields. The ranch headquarters has a well-preserved collection of building types, including residential, crop storage, animal control, and support facilities. The dwelling is a good example of Hispano/Linear Plan design and the above-ground adobe potato cellar reflects a building type once widely used in the San Luis Valley, but increasingly threatened. The site also contains archaeological ruins and artifacts that have yielded and are likely to yield important information about the use of the ranch over time, especially related to early Hispano settlement patterns in this portion of the San Luis Valley.
