Bill Young - How deep should we look for evidence of first Americans?

Three sites in Texas have been discovered and at least partially excavated in the past 15 years yielding evidence of at least one culture older than Clovis. Most of the Clovis sites have been firmly dated to around 12,500 to 13,000 years ago. Not only did these Clovis sites yield projectile points of the very distinct Clovis type, the sites also yielded true blades and very large well- made thin preforms diagnostic of only the Clovis people.

The archeologists who have worked at some of these Clovis sites have consistently noted the Clovis people utilized a very specialized type of flint knapping when they were producing either points or blades. This technique of flaking is easily recognizable to researchers familiar with Clovis. I personally can recognize both the points and the blades but when it gets down to the chipping debris left at a Clovis site, I am only able to identify a few things.
