Mound 101 and 102

These two mounds are surrounded by the 128 meter (419.9-foot) contour line, which was probably created by the leveling of the mounds. There is a high point, more or less in the center of this general area, at 128.2 meters (420.6 feet). Walking over the area, one detects slight rises in elevation at approximately the coordinates given for the mounds, indicating their remnants. Trenches would help determine if mounds had stood there prior to 1933. It would also suggest what data remain to determine the time of their approximate construction and their relationship to other mounds at the Cahokia site.
