In this vicinity are the remains of a prehistoric Indian refuse pile comprised mainly of clam shells, a kind of site archeologists call a shell midden. It resulted from centuries of shellfish harvesting by early Indian groups, and shells found here have been identified as Rangia cuneata, or common rangia, clams that were once abundant in Galveston Bay. As the midden grew over the years, it became the foundation for a large Indian campsite, and stone tools and pottery found here show later occupation. Although the tribal origins of the Indians at the site cannot be determined, both Orcoquisac and Karankawa are known to have lived in the area in historic times. Similar shell middens were once more common along streams feeding into the bay, but storms, subsidence, natural erosion, and mining of shells for road construction destroyed many of them. This site is therefore one of the best remaining examples of a prehistoric midden and campsite in Harris County and has been given special protection as a State Archeological Landmark.
