Hamilton Pool Facts
- Hamilton Pool ranks as another one of those incredible geological marvels that still remain virtually unknown outside of their own immediate area. However, it forms a popular destination for tourists who come to its area and then discover it.
- Two Native American tribes (the Lipan and the Tonkawa) of the Apache Nation, previously utilized the site until the 19th century. The site then passed to the Hamilton family in the 1860’s, who then sold it to the state in the late 20th century.
- This incredible site also now serves as the cornerstone of the Hamilton Pool Preserve, which the state established in 1985. The entire Preserve constitutes a protected area and covers 232 acres (93.9 ha).
Hamilton Pool Location and Physical Characteristics
Hamilton Pool has a picturesque beauty and may be located 23 mi (37 km) west of Austin, Texas, in the United States.
The water of the pool comes from a small waterfall which steadily feeds and maintains the pool. This small waterfall plunges approximately 50 ft (15.2 m).
It also never completely dries up. Yet it slows to a trickle at times, so the dimensions of the pool vary greatly. In depth, the pool stays quite shallow.
The surrounding rocks are composed of limestone, and the natural filtering action keeps the water a jade green. The pool is even surrounded by numerous large limestone slabs.
And last but not least, numerous stalactites can even be seen hanging from the ceiling of the underground portion.
Hamilton Pool Formation and Ecology
Geologists remain uncertain when Hamilton Pool formed, yet believe it happened at least 10,000 years ago. Its formation occurred due to erosion. The dome covering an underground river collapsed at that time, forming the grotto.
The stone overhang stays covered in dark green moss, and the banks teem with mountain juniper and small shrubs.
Several rare bird species also make their home around the pond.
Officials allow public swimming, yet carefully monitor the activity since they do not artificially maintain the water quality.
