These are remnants of a stone farmhouse owned by James and Melissa Bell Sublett, settlers who first came to Castolon in 1913.
Sublett is recognized for introducing mechanized farming into the Big Bend. He installed the area's first irrigation system supplied by a waterwheel.
Sublett hired Mexican laborers to plant the new fields with sorghum, corn, alfalfa, and other livestock feed crops.
By 1918, with the growing farm business in place, Sublett purchased 2,560 acres in this area and called it Grand Canyon Farms.
