This may sound like tourist-board hyperbole, but generations of Austinites have defined their city by this natural swimming pool in Zilker Park - a 1,000-foot limestone-bottomed spring that maintains 68-70°F year-round, flowing at 27 million gallons per day from the Edwards Aquifer. Native Americans used it for thousands of years. Spanish missionaries documented it in 1730. Developers dammed it in 1929, creating the current pool. Environmentalists have fought to protect it since the 1990s. The Barton Springs salamander, found nowhere else on Earth, was listed as endangered in 1997, limiting development over the aquifer's recharge zone. Barton Springs is where Austinites swim, picnic, discuss politics, and resist the forces turning their weird little city into another sprawling Sunbelt metropolis. It's a spring, a pool, a park, and an ideology.

Photo credit Mikerussell, CC BY-SA 4.0. The Barton Springs salamander (Eurycea sosorum) exists nowhere on Earth except in the springs and a few nearby outflows. When biologists discovered its limited range, they petitioned for endangered species listing, which would restrict development on the aquifer's recharge zone. ...

Photo credit Larry D. Moore, CC BY 4.0. Barton Springs is more than a swimming pool; it's a civic institution. Austinites swim here in January (shocking visitors with their cold tolerance). They discuss city council elections on the hillside. They measure Austin's changes by how the springs feel. When the springs occas...
