All four of these Clovis bifaces are
made of Utah agate. They all have a lanceolate form that suggests
they probably represent early stages of finished Clovis points.
The biface at top left was made with nicely done evenly spaced percussion
flaking. It measures 5 7/8 inches (15 cm) long.
The biface at top right is another example of a well made and better
than average flaked biface from the cache. It measures 7 3/4 inches
(196.5 cm) long.
The biface at lower left is described as having enough pressure
finishing-flaking done to the edge near the tip that it might
suggest its intended use as a knife. This biface also has two very
large end thinning flute flakes that were removed from both sides of
the base. This point measures 5 7/8 inches (14.9 cm) long.
The biface at lower right is typical of other examples in the
cache. It was bifacially shaped with very large percussion flake
removals and roughly pressure trimmed along the edges. This biface
also has one large end thinning flute flake scar on one side. The
large inclusion-flaw near the base possibly would have made it
difficult to finish the biface into a Clovis point unless its length
was reduced. This biface measures 7 7/16 inches (18.9 cm) long.
