The park is also home to a limestone slab, possibly a "stele", on which is a crudely carved human face and torso. This is odd because the slab is one that is not found on other mound sites except in locations such as the Caribbean, South America, and Central America. At this particular site there were at least four of these large stones placed by the inhabitants in their ancient time. This carving shows that the person represented possessed long hair in a plume over the left shoulder. There has been debate as to how strongly this inscribed stone slab was influenced by the monumental stelae of Mesoamerica. Although there may be some evidence for contact between the Huastec Culture of the Mexican Gulf Coast and the American Southeast, those claims which suggest the most direct connections are probably unfounded. The slab is today housed on the site within a metal cage.
