Spot on again! Either your eyes are still 20/20 or my photography is better than I thought. Yes, those are mostly feathered out. But what I'm doing for now is simply posting artifacts that are random isolates not connected closely to any site or any major debitage pile, a few flakes around at most. West of the Rockies there are some sharp dichotomies, which very few Archaic/modern choices are available. And Rondeau, Fagan, Beck and Jones, and several others that I can reference, pretty much agree that Western Stemmed manufacturing is overall quite different than Clovis when everything is taken together as a whole. When found in the same valley, for instance, Clovis is generally found separated from WS sites...but there are some exceptions of course.
So WS can be found with fluting, overshot flakes and so on, even some of the Blackrock concaves are very close in plan form and size, but none of these point styles contain all of the Clovis attributes at the same place that I know of. That's where Clovis differs, even without the Clovis points, John Fagan claims there is a distinct difference in manufacturing style at the Dietz site. So just how much difference has to be found lumped together at one discrete site in order for it to be reasonably certain it is a Clovis site?
I have a couple of more isolates to find in my morass of unsorted photos when I have time, then I will start in on the sites that contain a some mixing.
Another Western dichotomy is climate and Mount Mazama ash as a marker. In spite of the fact 14C dating is horrible out here, there are some conditions that can very easily separate Paleo from Archaic and the more recent material. Even though literally millions of Archaic and modern points have been found in the Great Basin and along the Columbia River, the dried lake beds show just the opposite distribution, with very few Archaic/modern styles found compared to Paleo styles. That's why the Clovis Quest program is confined to those locations where Archaic/modern sites are scarce.

While they are digging the rock shelters, they are also pedestrian surveying nearby quarries and dry lake beds at about a 1000 acres a year.
Thanks again Bob, you do have good eyes in spite of my photography skills.
