Chapman (1975:251) notes that Nebo Hill Lanceolate points are found in Northwest Missouri and the East half of Northeast Missouri. The diagnostic feature of this artifact is the fact that it is a long, narrow point. Chapman notes that length ranges from 50 to 100 mm. Perino (1968:60) notes that Nebo Hill points date to 5000 BC, and Chapman suggests a date range from 6000 to 2000. Excavation at the site before highway construction was able to narrow the date range to the Late Archaic Period (3000 to 1000 BC).
