The Edwards Aquifer Region sits on a karst landscape, a type of terrain where weak acids in rainwater slowly dissolve limestone, creating pores, fractures, caves, and underground waterways over thousands of years. 🪨💧 Famous sites like the Bracken Cave and Frio Bat Cave are part of this system, housing millions of Mexican free-tailed bats that emerge each night in search of insects, playing a vital role in our ecosystem. 🌎🦇 #EdwardsAquifer #KarstLandscape #TexasNature #BatConservation #Bracke
