The Geology of Barton Springs Municipal Pool
Barton Springs Municipal Pool is located atop the Edwards Aquifer, one of the most significant sources of groundwater in Texas. The aquifer is composed of several layers of porous rock, including limestone and sandstone, which allow water to flow through them. The unique geology of the Edwards Aquifer results in a karst topography characterized by underground caverns and channels, sinkholes, and underground streams and rivers.
The four springs that feed Barton Springs Municipal Pool emerge from the limestone and other sedimentary rocks that make up the Balcones Fault Zone, a geologically active area where the Edwards Aquifer meets the surface. The springs provide a glimpse into the geological history of the area and the processes that have shaped the land over millions of years.
