Looks like three large gophers have been helping you. The site looks great with lots of promise. I am waiting to see the first corner tang picture in the near future. Great flint, great pics. Keep them coming.
Good report Flo, With your known experience I wouldn't think to preach...but for some, note that all the found points are well bleached ( Either natural chemically or sunbaked ).. that says that that particular area is probably not the heart of the camp.
