San Antonio Spring "Blue Hole"

San Antonio Spring, or Blue Hole, is the mainspring in a field of many artesian springs that arise from the Edwards Aquifer and form the headwaters of the San Antonio River. Known as Yanaguana, meaning Spirit Waters, this spring was once a gushing fountain spring pushed to the surface under tremendous artesian pressure. Today pumping from regional water wells has caused the springs to go dry, and they flow only during very wet times of extended rainfall. Even so, the place is considered sacred ground, celebrated by many over thousands of years.
