Howdy folks,
Our vacant lot has s flint/chert quarry right next to an Amerind camp. Seldom find a finished piece there as it was apparently used to manufacture what we call "trade blanks" Basically these were percussion flaked large bifaces that could be used to manufacture large finished points or knives. By making these to trade it eliminated the need to transport heavy nodules large distances. The largest piece on the right is almost a foot long. The long pointy one in the middle is something I've never seen before, triangular in cross section and flaked at a very steep angle. Tip is worn almost like it was some kind of digging implement. I've seen similar "picks of obsidian near Clear Lake in California but this is a first for this ranch. The two smaller pieces on the left are about four or five inches and are the more common sort of blank I find. Expect these were used to make projectile points which around here were spears or atl atl dart points.
