What do you think? Indian or not?

I am not sure to make of this pile of rocks. What I have found were several hundred rocks that have definitely been broken into shards. The majority of them do not look worked on but all have the same M.O.:
One side relatively sharp
Other side flat (blunt)
All fit in hand easily

I am positive this is not a natural occurrence but am not convinced they are Indian artifacts either. I have posted some picts but I am not too happy how they have come out. Please let me know what you think. I should also mention I found these right off the St. Joseph River.

They look natural to me. Various granites and similar materials weren't used very often- they are difficult to work and don't have the properties that are needed for most stone tools like concoidal(sp?) fracturing.

I did not know that. I guess something seems very odd about this location. All of the rocks have been split or broken but why? Again, I agree with that I don't get the feeling these are indian artifacts, yet something is just not right. I dunno.

I, D CALL THEM BROKEN ROCKS. Jeff

I suppose you are right. Realizing,of course, it is beyond the scope of this forum, I wish I knew why there are all of these broken rocks in this one location.

I don't blame you, I would too. I think they used granite type materials quite often. I have discovered that modern rock crushing processes can create edges on granites, and that gets in streams from bridges and such. I was finding pieces of this unfamiliar red granite with really good edges, some even looked like points. After realizing that I only found them downstream of a railroad bridge, I discovered were red crushed granite from the railroad tracks was spilling into the creek. Man, glad I didn't post none of those.

they didn't use granite type materials quite often As far as finding them broken, could be any number of things but it's natural, rocks break and break, from large boulders to small boulders, eventually to gravel and even to sand... it's a long natural process that can happen in a nubmer of ways, the process behind how the rocks in your area is going to be explained by the pre-history of that area. Glaciers raised heck with the land, breaking off, grinding up, and carrying stones a long way. Sometimes it's as simple as water errosion by frost, usually you think of water errosion you think of smooth cobbles in a stream but not always, in northern climates you may have water seeping into small fissures and what not in a stone and if it's close enough to the surface come winter the water will freeze, expand, and possibly break the rock. The list is almost endless. If I were you and really wanted to find out I would take a few of those to the Geology department of the local college and find out what the scoop is.

Good call. I think I will do that.
