Southern facing side of hills near water sources (springs, creeks, river/river floodplain) in Brazos and surrounding counties likely have sites containing artifacts. In the Brazos valley, it is not uncommon to find sites along meander scars in the bottomland. I know probably 100+ sites in Brazos Co. with varying ages of deposits. The Hall of Fame site's parking lot was an amazing area of Paleo aged (and of course some more recent) points and was partially covered in asphalt. When the new Walmart goes in, I suspect many locals will be out looking around. The area where Traditions is located had dozens of sites that many old timers around here used to take their kids out looking for points. Where I live, some old timers told me they picked up points in buckets back in the 50's when the sandy soils were constantly turned over by pocket gophers. After a good rain, points from recent arrowheads to paleo projectile points have appeared on my land, as well as atl weights, knives of very fine chert evidencing world class flintknapping skills and a lot of areas of sustained and repeated campfires leaving heavily charred and fused sand and occasional animal teeth behind. Also choppers, rough tools, pieces of crude pottery, chert chips from the knapping process, & tools I can only speculate as to their use (and read about others well intentioned speculation). There is more myth than fact among a lot of people that are, as described above, pot hunters.
As mentioned above, many of the local sand and gravel quarries along the Brazos have extensive artifact contents. I spent some time working my way through college doing landscape work and recall the many pieces of arrowheads and spearpoints in loads of gravel and sand delivered to jobsites. Several off FM 60 west of town were located in artifact laden areas. Even public road and rail cuts out near Dansby power plant would reveal extensive artifact deposition. Lake Somerville is pepppered with sites, but I'm almost certain that it is illegal to mess with artifacts out there.
Mammoth kills have been discovered and extensively studied along the Brazos River. You might want to start by educating yourself to local work performed by guys like Harry Shafer and reading Suhm and Jelks work as well as books available through the Texas Monthly Press on the subject.
http://www.sciencedaily.com/releases/2001/02/010202074234.htm I will say that significant damage to sites can occur from amateur digging and often compromise the ability to maximize the information available to scientific investigation, but without the exchange between archeologists and lots of amateurs, many sites may have never come to the attention of professionals. The two sides of this tug of war usually have pretty strong opinions about the morality of disturbing sites, and many laws apply in cxertain areas and with particular objects.
