This picture shows three of the four Clovis points that were found
on the Colby mammoth kill site in north central Wyoming. The point
in the center is the largest complete Clovis point found on the Colby
site. It was found by Donald Colby in 1962
while using heavy
earth moving equipment during the construction of a reservoir. It's made
of banded chert from the Madison Formation and it measures 3 11/16
inches (93mm) long.
The point on the left was
found during the 1975 excavation. It was found in bone pile number 2
below a row of ribs. This point also has the "Colby style base"
which is a base that is more rounded and a concavity that is
becoming almost "notched." This point was probably resharpened at
least one or more times. It's made of a dark red Phosphoria Formation
chert and measures 2 3/16 inches (56mm) long.
The Clovis point on the right was found during
the excavation of bone pile number 1 near one of the ribs. It's a
good representative example of a "classic" style Clovis point. The
base of this point is not as rounded and deep as the three other
examples found on the Colby site. Both channel flakes were removed by percussion. This point is made of a
translucent Phosphoria Formation chert and measures 2 1/2 inches (61mm)
