projectile points

Any anthropologists out there

I am a amature anthropologist. Been a member of the Kansas Anthropologist Assn for 15 years ago. Found this corner notched point near a playa a couple weeks ago. Not sure what it is made of.....possibly Black Owl creek chert from mid Texas. Anybody else have pictures of artifacts to show?

Aj was the back of the point broke off or was it made that way? I have found a few that looked like that but I always thought the back was broken off. We have found some that were from a black stone that looked similar to that but figured it was obsidian, usually very small points. Most of the points we find are either brown or gray. Doesn't seem like I find many anymore, I guess I don't look for them as much as I use to.

I have never found a projectile point but I have found a few hammer heads.
This one I found as a kid on top of a rock pile.

mtnman. I think the base is broken off the point I pictured. You rarely find a complete point because they were to valuable to leave laying around. They discarded the broken ones because they either broke on impact or during manufacturing. Alot of points that are found are actually atlatyle points......not bow and arrow points. I also think that people tend to think that in their area......a certain tribe existed. That may be true. But over a 12,000 year period there were most likely several "tribes" that passed through an area. Coyote....that is so cool. I am half way through writing a book about a ancient indian traders trail that ran from Mexico into the present day Canada area. Canada is a big part of the paleo indian aspect. Is your deal round or more shaped like a pancake?

obsidian is glasslike. It can produce some very sharp edges. Some surgeons today use obsidian blades today because they can be sharper that a metal handmade blade. mtnman......do you live in the mountains or foothills or the plains area?

I have found several hammer heads over the years and have given them all to a local museum. Several years ago, after a very dry summer with a couple bad wind storms, a couple asked me if I would allow them to walk across our farm and look for arrow heads. I was amazed when they came back into the yard a few hours later with several of them. My dad says he used to find lots of arrow heads when he was young but I haven't found any... but then I haven't looked real hard either.
I have a 1000 acre native pasture that has several teepee rings in it. They are still very visible and have never been disturbed except for cows walking over them. They are stones placed in a circle that were placed around the teepee to hold the teepee sides down. There are about 8 or 10 of these rings so it must have been a place where a tribe spent some time. I have always thought that there is a good chance there are lots of artifacts around them, but it would require disturbing the grass and doing some digging.

Waldo Wedel points out......in the current book I'm reading that early in in the anthropologists theories of this area concluded that the bison couldn't have been the main source of substanence for a people living in the "rain shadow" of the Rocky mountains. THEN........sites like Olsun-Chubbick and Jones Miller were discovered. It is thought that natives in this "great american desert" didn't obtain horses untill at least Coronado introduced them in 1541.......to this rain shadow area. Interesting how theories and concepts of history and prehistory change as knowledge advances. People killing and harvesting bison and mammoth for that matter 12,000 years ago.
