Near Glen Rose in Somervell County, Texas — The American South (West South Central)
Deep Water Shelter
The Blue Hole is located on a rocky ledge down to your right.
Millions of years ago, a small pack of fierce predatory Acrocanthosaurus dinosaurs left tracks in soft mud near here most likely while hunting down prey.
The Blue Hole site is underwater for most of the year and well protected from freeze-thaw damage. Slow-moving water along this straight and wide section of the Paluxy River has also protected these tracks from erosion.
A Popular Swimming Hole
The Paluxy River has been popular with local residents since the 1800s-long before the discovery of dinosaur tracks here.
