The Hamilton Basin is one of the most interesting natural formations in the state of Texas. The formation of the pool is quite interesting. For a long time, an underground river flowed here. Thousands of years ago, due to continuous erosion, the arch of the underground river collapsed, leaving the pool open.
The resulting body of water is sometimes referred to as Lake Hamilton. The uniqueness is that half of the pool lies under a limestone canopy. This is what gives this place a fantastic look. Where is the Hamilton Basin located 40 kilometers west of the city of Austin in Texas in the south of the United States. Geographic coordinates 30.342385, -98.127017
