Clarence B. Moore, who visited the site in 1908, described Mound A as being 25 feet (7.6 m) tall, although by the 1950s it had been significantly shortened. Mound B has been almost completely leveled, although a small rise can be discerned. Mound C is roughly 12 feet (3.7 m) tall. Mounds A and C are both roughly 120 feet (37 m) sq. Pottery sampling in the 1950s from Mound A gave the site a historical importance out of all proportion to its size. Test pits from a 1949 excavation of the Holly Bluff Site produced an important glimpse of a late "transitional" Coles Creek to Plaquemine assemblage featuring thin tapered rims of polished plain ware and carefully executed varieties of Coles Creek incised and associated types. Although intriguing as pottery, it was not sufficiently integrated strategraphically to postulate a distinct phase. Site sampling from the Kings Crossing Site in 1954 supplied the integration and gave the phase a name. Since then, especially in the Tensas Basin, it has become one of the firmest and most easily identifiable ceramic complexes in the Lower Mississippi area.
In 2005 the Kings Crossing Site was portrayed on the Vicksburg Floodwall Mural project to represent the American Indian heritage of the region.
