I've only been hunting artifacts since March of this year and have really come to enjoy it.  I feel as you that I am preserving history.  Where I hunt is all in production farm land and all finds are surface finds.  I feel that if I don't rescue them farming operations will destroy them and they will be lost forever.

I have found quite a few good points, a bunch or broken points, what I think are unisurface knives & assorted tools and one find of a lifetime. 
  
First I should explain the find of a lifetime because when I do and if you try to look it up in Overstreet you'll wonder what the heck is going on. I found the point on June 27th, also a  surface find on a ridge in Crittenden county Arkansas that was an ancient bank of the Mississippi.  From the lay of the land I would have actually been on the TN side of the ancient river. It is 6 inches long and 2 1/2 inches wide at its widest point.  

I sent Tom Davis an email with a scanned picture of the point.  He encourage me to hand carry the point to him in Stanton KY if there was anyway I could.  I went to KY last weekend, 7-13-2002.  Tom graded it a G10 Ocala type.  He said Overstreet did not have a picture of an Ocala in my region, SC, and that he would send me an extra copy of the picture and Overstreet's address because he felt they would want to include it in the next edition, 8th edition I guess since I have 7 now.   Tom gave me a copy of a page from a 1975 book "identifying florida projectile points" (or something close) with the description, distribution etc. of Ocalas.  It said the point was 7,000 - 9,000 yrs old.  Upon returning to Marion AR I decided to look up the Ocala in the GC (Florida) region of Overstreet's book just to see the example they would have there and compare it to mine.  What a surprise I got.  There was a one line entry beside OCALA.  paraphrased "Ocala points do not exist, they are all misidentifyed Lafayettes or northern something imports" .  I called Tom with this information and he said he would do more research.  

I talked again with Tom on Wednesday, 7-17-2002.  He told me he had just had a long discussion with Bob Overstreet and had gotten to the bottom of the issue. It seems the entry in the 7th edition is a combination of incorrect information from one source and Bob's misunderstanding what another source told him.  The first person told Bob that Ocalas do not exist.  I assume Mr. Overstreet wanted confirmation so he contacted his second resource.  This person evidently told him that Ocala points are very rare outside of Florida and the ones found usually have a northern influence.  My comment: I guess a northern variation of Ocala. Any way things got confused and the entry that they do not exist was published in error.

The 1975 book stated the distribution of the Ocala to be Florida and north to SC and northwest to LA, the TN valley, NE Arkansas and SE Missouri.

When I get the papers from Tom I will forward copies to Overstreet and hopefully we'll see my point in the book next year.

PS Love your site, I just happened to stumble onto it looking for pictures of arrowheads.
