1. Found in Larimer Co. CO in the 1920’s. This magnificent platter measures 9-3/8” x 4 -3
/4”. It is made of Ogalala Quartzite.
2. Uniface flake knife of Florence chert found in the Arkansas River, Tulsa Co. OK. 3 -5/8”
3. Dent Clovis. Drawn from a cast by Jim Chase. 3-1/2” x 1-7/16”. Discovered in 1933, this
mammoth kill site was later dated with a range of 11,200-10,600 BP.
4. Found in Ohio and sold with a family collection. 3” x 1-5/8”
5. Found in W. MO and sold with a small collection. 2-7/8" x 1-1/2"
6. Found in Tulsa Co. OK, 2007. 3-1/2” x 1-7/16”. The piece displays extremely heavy
patina observed on many Boone Chert Clovis artifacts from the Arkansas R. in NE OK.
7. Kansas Platter- Geary Co. KS. 9-1/2” x 4-1/2”. Used as a cleaver at one end, and a
knife at the other, wear and sharpening begin to reveal the shape of a Clovis spear point
concealed within the biface. Multifunction tools, the platters also served as cores. The large,
sharp flakes they furnished made high quality knives, tools, and points.
8. Smaller Clovis knives were more likely to become spears. This Clovis knife/preform from
the Arkansas River in Tulsa Co. is made of Boone Chert, and is 3-3/8” x 1-5/8”. It exhibits
patination similar to #6. Another pass or two by the knapper, and it would have looked like #19.
9. Jake Bluff Clovis. Excavated at the Jake Bluff Site in W. OK. Drawn from a Jim Chase
cast. Made of gray quartzite. 3-1/8” x 1-3/8”. This site is in close proximity to the Cooper
Folsom Site. A Clovis Bison kill, Jake Bluff was dated to 10,750 B.P.
10. Discarded point. 1-1/4”x7/8”. This example shows less basal thinning than other
examples pictured here. Its present condition shows it was hafted and used to exhaustion
11. Found in the Arkansas River, Tulsa Co. OK. 6” x 1-3/4”. This large Clovis knife is
made of Kay County flint and has a heavy, chalky patina. Fine percussion sharpening covers
most of the blade. Two short thinning strikes have isolated a striking platform on the base. This
knife could be used as a lance, but needs further reduction to serve as a spear or dart point.
12. Kimmswick Clovis. Drawn from a cast by Pete Bostrum. 4” x 1”. Clovis points like this
were associated with mastodon bones at the Kimmswick bone beds, a salt spring near
Kimmswick, MO. The site is now Mastodon State Park.
13. Clovis Dart Point, Tulsa Co. OK. Made of Barron Fork, a sub-type of the Boone
Formation. 2-3/4” x 1”. Knife use is evident on one side of the blade, impact crushing on the tip.
Rounded tips help control damage from projectile use.
14. Clovis Dart point. Found in the Arkansas River, Tulsa Co. OK. 2-1/8” x 1”. Made of
Boone Chert, it has a dark, heavy patina. A massive impact fracture has been repaired, but is
still visible from the side not drawn.
15. Clovis Point found in Tulsa Co. OK. 2- 9/16” x 1”. It is made of Boone Chert with the
dark, crust like patina seen on many Tulsa Co. Clovis pieces. It has damage to one basal
corner. This dart or spear point is in good, serviceable shape and was probably lost by a
hunter more than 11,000 years ago.
16. Found in the Arkansas River, NE. OK. 2-1/2” x 1-1/8”. Made of Florence Chert, this
artifact shows damage to the hafting area. It has use/wear seen on hafted knives, but may also
have served as a spear point.
17. Found in the Arkansas River, Tulsa Co. OK. 2-3/4” x 1-3/16”. This Clovis knife/preform
is made of Boone Chert and exhibits the dark Clovis Phase patina. It shows little use since it’s
last sharpening. The haft area is undefined. Bases are not finished until the points are needed,
as each shaft was slightly different.
18. Found in the Arkansas River, Tulsa Co. OK. 3” x 1-3/8”. This Clovis knife/preform is
made of an unidentified black flint, and shows knife use. It was likely a butchering tool. A
remnant dip on the side not illustrated indicates this artifact was made from a mega flake.
These knives also serve as preforms for Clovis spear points. Note the similarities to the
putative “Haw River” type.
19. Found in the Arkansas River, NE. OK. Made of White Boone Chert with caramel
colored patina, 3-1/2” x 1-3/8”. This Clovis Knife/preform is very similar to # 18. Thinning
strikes at the base have isolated a striking platform. Sharpening from the tip will leave stacks
near the centerline at the base. These will be removed with the final thinning strikes.
20. Excavated at Blackwater Draw, NM. Drawn from a Jim Chase cast. 4-1/4” x 1-7/16”.
Black Water Draw is the Clovis Type site, and has been carbon-14 dated to between 11,000 –
21. This example is made of white Mississippian Formation Chert. 3” x 1-1/2”. It is nearly
uniface, being made on a mega flake. It has been used as a knife, and sharpened several
times. From an old collection in E. KS, its provenance has been lost. Many of these orphan
Clovis artifacts exist.
22. Found at the Colby Mammoth Kill site, Washakie Co. WY in 1963. 3-1/2” x 1-7/16”.
This site dated in the 11,200- 10,800 range.
23. Excavated at Blackwater Draw in association with other Clovis artifacts. 1” x 5/8”. This
small point is made on a flake and is essentially uniface. Drawn from a Jim Chase cast. 11,000-
11,500 B.P. range.
24. Found in the Arkansas River, Tulsa Co. OK. 1-3/4” x 1”. This surface find from alluvial
gravel is very similar to flake points from the Clovis level at Blackwater Draw. It is made of
Permian Chert from the Florence Formation. Large platter bifaces could furnish many such
flakes of high quality material.
25. Excavated at Blackwater Draw, NM and drawn from a Jim Chase cast. 1-3/8” x 13/16”.
This small knife or point is made on a flake, and was associated with Clovis artifacts. These
small points may have been hafted to a foreshaft.
26. Excavated at Blackwater Draw, NM and drawn from a Jim Chase cast. 1-1/2” x ½”.
This mostly uniface example has a well ground base, indicating it was hafted as a dart.
11,500- 11,000 B.P. range
27. Excavated at Blackwater Draw, NM, and drawn from a cast by Jim Chase. 2” x 13/16”.
This point made on a large flake has a ground, constricted haft area. A projectile, it has very
sharp edges and an acute tip. 11,500-11,000 B.P. Range
28. Found in the Arkansas River, Tulsa Co. OK. 3-1/2”x 2”. This medium large sized flake
tool is made of dark Boone Chert with a very dark charcoal colored patina. It has been used to
cut and scrape some harder substances, such as wood or heavy rawhide. The artifact has
