📘 A city parked on

What you’ll learn

1. Springs and the faultRead how Balcones faulting and Edwards aquifer springs fixed where San Antonio could grow.Warm groundwater at the escarpment made the first settlements possible on the prairie edge.
2. Missions and the riverConnect the mission chain, acequias, Alamo siege, and 1921 flood to the same river line.Missions farmed the spring-fed river; later engineering held and walked the water through downtown.
3. Modern San AntonioSee military bases, groundwater dependence, and suburban growth as layers on the spring town.Forts, Edwards pumping, and loop highways reshaped a city that still drinks the same limestone.
