One of the most significant Paleo-Indian archaeological sites in Northwest Missouri is the Peterson Site situated between St. Joseph, MO and the Iowa border.
Complete clovis point from the surface of the Peterson Site, 2013. Length = 65.5 mm, width = 23.4 mm, thickness = 7.1 mm, and weight = 9.6 grams. Long flute = 19.8 mm, short flute = 9.4 mm, basal indentation = 3.8 mm, basal and lateral grinding.

Resharpened clovis point from a dark gray (non-local) chert with an impact fracture from the surface of the Peterson Site, 2013. Length = 39.0 mm, width = 24.5 mm, thickness = 5.4 mm, and weight = 6.7 grams. Long flute = 34.6 mm, short flute = 20.2 mm, basal indentation = 4.3 mm, basal and lateral grinding. Thickness at flute = 4.7 mm.
Clovis point that failed in manufacturing at the stage where the nipple was prepared for the flute. Length = 32.3 mm, width = 32.9 mm, thickness = 6.9 mm, and weight = 9.2 mm.
Clovis point from speckled white chert found in 2013. Length = 45.9 mm, width = 20.2 mm, thickness = 6.5 mm and weight = 6.0 grams. Long flute = 13.4 mm, short flute = 9.8 mm, basal indentation = 3.1 mm, basal and lateral grining, and faint serration along one edge at the midsection. Thickness at flute = 3.8 mm. [Chambers]
Resharpened clovis point found in 2013. Length = 37.4 mm, width = 17.7 mm, thickness = 3.8 mm and weight = 3.0 grams. Long flute = 23.8 mm, and short flute = 22.9 mm. Thickness at flute = 3.2 mm. [Chambers]
This website is designed for use by school children, amateur archaeologists and professional archaeologists. The identification of the site is very general because the site is not open to visitors or artifact collectors. An "estimated" age for the site is 9550 BC (based on parallels to excavated Clovis sites that have yielded charcoal for C-14 dating). The site was discovered by Mr. S. Peterson, an amateur archaeologist. Testing during 2013 recovered fire cracked rock; a sample "may" be used for a TL date (Thermoluminescence).
Archaeology team from St. Louis Community College testing the site during April of 2013; the STLCC fieldwork was a servive learning project for students enrolled in ANT 104.
Archaeology students, Professors Abbott and Fuller (front row, far right) and Steve Peterson (back row far right) during the excavation of three test pites during April of 2013. Test pit 1 (right) is open while test pit 2 (left) had just been backfilled. Test pits 1, 2, and 3 were hand excavated and screened. Soil samples were taken for archaeobotanical analysis by Professor Monte Abbott.
Plowzone, burrows, and two pieces of chert below the plowzone in Test pit 2.
The site is not in the main Missouri River valley. It is situated several miles east of the main valley, on a high hilltop with a small seep spring situated nearby. The high elevation and nearby seep spring are landscape traits that it shares in common with the Martens Site near Chesterfield, Missouri. The Peterson site is in a very different landscape setting from the Kimmswick Site situated in Jefferson County, Missouri. Site size is esimated at 10 acres making it at least twice the size of the Martens site.
