Also, Callahan (1979) did a great job making a modern facsimile which can be found on page 132, fig 59 here:

This means that Clovis sites in the Great Basin, Colorado, Texas, Missouri, Kentucky, and Virginia (literally coast to coast) have some attributes that are very homogeneous.
I have now found 4 basal and 4 distal examples that are identical to Callahan's example on page 132. When I say identical I mean, without prior knowledge of material types,
one would not be able to separate out what I've been finding in a blind test from either Callahan's replica or the Clovis examples from other states.
I also found a broken basalt hammer stone at one of the sites. When I got home I found a few small basalt cobbles in a local creek bed and have been practicing making over shot flakes and looking at the
Wallner lines. You can see in the last photo that those lines are very coarse. The lines made by my basalt hammer stone and a large moose billet are in contrast very, very fine. But guess
what? I don't know a thing about how they measure those lines, so I don't know if looking at them visually is telling me anything or not. I'll worry about that later.
