Nice collection guys. Lots of good atlatl points.
I have a small collection myself of spear heads, atlatl points, drills, and a few arrow heads... But It makes me cringe to know that they are found via plow and till. From an archeological standpoint, plowing destroys most of the useable data that could have been gleaned about the Pre-Columbian cultures that lived here in Indiana.
We know very little about these people, who we call "Mississippians" or " the mound builders" - umbrella terms for a number of very similar people and cultures that inhabited this region long before the arrival of familiar 'Indian' tribes such as the Miami, Potawatomi, and Kickapoo.
I would be interested in knowing if HogMans "honey hole" has any rises or small hills located in or around that field?
What we do know about these people blows the modern stereotypes of "Eastern Woodland" and "Great Plains" natives out of the water.
These were not nomadic hunters organized in tribes or family bands but rather state-like civilizations of consolidated power, who lived primarily on agriculture but supplemented their diet with wild game. They build fortified cities, some of which housed as many as 50,000 people (see Cahokia). These cities, as well as their smaller settlements, were often built on top of hills or rises, in close proximity of water - water which acted as highways for trade. Countless ruins of these type settlements have been plowed or graded in oblivion by unknowing farmers and land developers, yet those are the very sights which hold the keys to understanding these lost cultures. Artifacts from Indiana mounds have been found from as far away as the Gulf of Mexico, and the Rockie Mountains. We also know that their cities contained ritual plazas, large earthen platforms similar in shape to Aztec or Mayan structures, and that they may have shared some similar religious iconography (serpent and other deities).
Of course, this was only a small portion, and likely the pinnacle, of Pre-Columbian civilization in our region. They were preceded for thousands of years by unknown cultures of hunter-gatherers, and maybe even other large civilizations that have been lost to time.
This is why it is important to document any finds you make, ESPECIALLY if you find one on a trail or riverbank that has never been plowed.
