Founded on the banks of the San Marcos River, the area is considered to be among the oldest continuously inhabited sites in the Northern Hemisphere.

Archeologists have found evidence at the San Marcos River associated with the Clovis culture, which suggests that the river has been the site of human habitation for more than 10,000 years. The headwaters of the cool, clear river are the San Marcos Springs, fed by the Edwards Aquifer. The San Marcos Springs are the thirty largest collection of springs in Texas. Never in recorded history has the river run dry.
