A typical Clovis point is a finely worked, pointed tool with the marks of many strikes on it. The tools recently found in Colorado may be from the era of Clovis stone tools, but they are not exactly Clovis points–Clovis bifaces perhaps.
The fine, fat stones shown in the picture are from a cache of blanks. They are stone-tool material, roughly cleaned up into at the quarrying site and then stored in a more convenient location against need. The owners planned to return to this cache when they needed to make tools.
