Centinela Springs
United States
The Aguaje de Centinela, or Centinela Springs, was a valued source of local spring water for Rancho Aguaje de la Centinela and what is now southwest Los Angeles and Inglewood in Southern California. The spring was known to prehistoric people and animals but the name aguaje, meaning watering place, comes from Spanish–Mexican era of California history.
