to restore Hamilton Pool. Now, as a result of the restoration plan, the ecosystems of Hamilton Pool are recovering. Ongoing land management practices at Hamilton Pool Preserve include prescribed burns, prairie restoration, endangered species surveys, biological inventories and water quality monitoring. In February 2021, a series of five winter storms, including Winter Storm Uri and Winter Storm Viola, swept through Texas in rapid succession. Ice wedges formed in the overhanging cliff and the frequency of rockfalls greatly increased, resulting in the closure of the pool itself. A portion of pool re-opened for swimming in May 2022 but has intermittently closed since then due to high bacteria levels. The trail underneath the overhang remains closed. Ecology Flora The preserve is home to the chatterbox orchid (Epipactis gigantea) and the eastern red bay (Persea borbonia). Other Filming location The 1990 movie The Hot Spot, the 2007 film Teeth the 2010 film Predators, the 2011 film The Tree of Life, and the 2015 music video for the song "Charlie Gray" by the Dallas-based indie-rock band Valise all filmed scenes at Hamilton Pool.
