where is the hamilton pool preserve in texas
Hamilton Pool Preserve Hamilton Pool Preserve is a natural pool that was created when the dome of an underground river collapsed due to massive erosion thousands of years ago. The pool is located about 23 miles (37 km) west of Austin, Texas off Highway 71. Since the 1960s, Hamilton Pool has been a popular summer swimming spot for Austin visitors and residents. Hamilton Pool Preserve consists of 232 acres (0.94 km2) of protected natural habitat featuring a jade green pool into which a 50-foot (15 m) waterfall flows.
Marble Falls, Texas Marble Falls is located in southern Burnet County at 30°34′N 98°17′W﻿ / ﻿30.567°N 98.283°W﻿ / 30.567; -98.283 (30.5741, -98.2782),[9] on the banks of Lake Marble Falls. According to the Handbook of Texas website, the former falls were flooded by the lake, which was created by a shelf of limestone running diagonally across the Colorado River from northeast to southwest. The upper layer of limestone, brownish on the exterior but a deep blue inside, was so hard and cherty it was mistaken for marble. The falls were actually three distinct formations at the head of a canyon 1.25 miles (2.01 km) long, with a drop of some 50 feet (15 m) through the limestone strata. The natural lake and waterfall were covered when the Colorado River was dammed with the completion of Max Starcke Dam in 1951. A photo of the falls as they once existed can be seen at the website for the Wallace Guest House, a local bed and breakfast.[10] Lake Marble Falls sits between Lake Lyndon B. Johnson to the north and Lake Travis to the south. The falls for which the city is named are now underwater but are revealed every few years when the lake is lowered.
