These are actual Sauropod (Dinosaur) tracks from the Jurassic Period. The main set of tracks meanders down the middle of the Blanco riverbed from west to east (left to right). It is crossed by at least 5 other sets of tracks running north to south. These tracks have been a rumor around Texas for years, but they do actually exist. They are not part of any State or National Park yet. They are surrounded on both sides by private property, so if you decide to visit them, take all the photos you want, but please respect the local homeowners. Don't litter, deface, or damage anything.
