Spirithawk, You have a beautiful collection. Obviously they chose you to find them, although i don't doubt your skill in the hunt.
I too have always been amazed that there are so many projectiles lying around until i realized the size of the native Americans villages during the woodland period, the scope of their trail network and the huge amount of trading done. might find arrowheads from flint knapped off in Ark in any state you find them in. Our own morrow mt in the piedmont section of N.C. was known for its quality flint and was traded far and wide among the natives. Nothing would be more thrilling here in the south to find an obsidian point.. they're certainly out there..
My few points in this pic are the ones i've found during hunting outings, with a few exceptions they were all found in Charlotte N.C near what was a large village of Sugaw indians off 12 mile creek. A kind farmer who owned the land showed me where their village and original field outlines stood beside the creek, he said the 100 yard wide strip of land containing their crops went beside the creek all the way to lake wylie, some 6 miles away. 6 miles of planted land shared with the Catawba indians. Amazing. A book i later read about this areas natives confirmed many miles of planted areas along the creeks of the region. those arrowheads i've come across always seemed to me to have wanted to be seen, right in my face. Only a mile or so away is a landmark known locally as the "big rock", its a 5000sq ft rock, sitting alone in a forest with nothing else like it anywhere around. It was known to Wanderers as far back as 30,000 years according to recent digs. On its face, is dozens of carved out ovens with a lower fire chamber and upper baking or smoking shelf(see pic) I grew up roaming those same forest as umpteen thousands of other kids many thousands of years before me. We walked the same trails, we camped the same sandy creekside beaches, we walked in each others footsteps and when in the woods i never forget them, actually realized many times they're still there. By the way, the 2 pieces of pottery and the birdpoint were not Sugaw or Catawba but rather were found on the edge ofan oyster shell pile on edisto island S.C. when i was much younger. The birdpoint is bone i think and not very old i'd guess.
I like seeing the differences between points, you can spot a masters work from an apprentice easily enough but it was interesting to learn that good or bad arrowheads still follow the same exact patterns if of a similar age, even arrowheads of similar age from different states will be amazingly similar in size and design. The Native Americans were much more organized and civilized than they were given credit for.
