This four-thousand-year-old projectile point is nearly one foot long. A point of this size was not likely an effective tool for deer hunting. However, it may have been a powerful symbol used in rituals to ensure a successful hunt.

During the later stages of the Archaic period, Native Americans in Illinois changed the way they treated the remains of someone who died. Instead of burying them in unmarked graves as they had done for thousands of years, Late Archaic people began marking graves with mounds of earth. Mounds soon became cemeteries with numerous graves. As the number of graves increased, so too did the size of the mound. Late Archaic people also placed unusual objects with the remains of the dead. These objects probably related to the accomplishments of the person.
