In February 1957, Sam Whiteside of Smith County, Texas, excavated a burial at 41SM53. This site was designated P-4 in Mr. Whiteside’s notes and it was one of several Caddo sites along Prairie Creek in the upper Sabine River basin that he investigated to varying degrees in the 1950s and 1960s. As an a vocational archeologist Mr. Whiteside made many important contributions to East Texas archeology. Dr. Dee Ann Story, of the Texas Archeological Research Laboratory at The University of Texas at Austin, who corresponded with Mr. Whiteside, later obtained the trinomial 41SM53 for the site
