The Ortega Farm in San Luis is Colorado's oldest centennial farm. It was originally granted to Praxedes Vigil Ortega in 1851 and has remained in the Ortega family ever since. The farm is now operated by Praxedes Ortega's great grandson, A. Prax Ortega, Jr. The farms major crops are alfalfa and oats, with part of the land being used for permanent pasture.
