Sometime in 1820, Luis María Cabeza de Baca traveled from his home in Peña Blanca to Santa Fe, and then to San Miguel del Bado.
Don Luis, as he was known, was apparently looking to expand the already large land holdings he owned in and around Peña Blanca, which is located in Sandoval County, west of La Bajada. In San Miguel he heard about lush and extensive pasture lands located along a river to the northeast, and he joined eight others from San Miguel in filing an application for a grant of those verdant vegas.
