Seven Hundred Springs pours out from the bottom of a cliff surrounded by the arid landscape between Junction and Rocksprings Texas. Green ferns and moss grow between the cascades of clear water gushing over the white limestone. The spring is the 11th largest spring in Texas, and supplies the South Llano River with thousands of gallons a minute of clear, clean water. The aquifer under the rocky soil in Edwards County has never run dry. Even during the seven-year drought during the Fifties, the springs continued to flow.
