In 1834 and 1837, territorial governors divided these lands between two brothers, Alejandro and Francisco Rodriguez. Alejandro Rodriguez was granted Rancho Arroyo del Rodeo, named for the "rodeo" (cattle roundup) area located in a low-lying natural amphitheater along Rodeo Creek. (These grounds were later filled in during the construction of Highway 1.) Francisco Rodriguez was granted a rancho bearing the name "Los Esteros" (never patented) because of the sizeable estuaries forming two of its boundaries. Originally known as Twin Lakes, the westernmost of the "twins" is now the Santa Cruz Harbor.
