Please help me ID these Michigan points

[sofasurfer]

Can anyone help me ID these points? I have posted to other forums and nobody seems to know what they are exactly. I'd like to know if they are arrowheads or spear points or what? Also who made them and when? Are they rare or common? I have seen many arrowheads from the area but never any that are this nice and large. They were found in Lapeer County, Michigan. The round base point measures 2-3/4"X1-3/4".
The other measures 2-3/8"X2", but there appears to be 1/8" chipped off of the tip.
Thanks.

EDIT: The pics are in the next post. The ones from this post were way to big so I deleted them.

wow, your way far away from me, but to help encourage you/people from looking at a book i would guess "Wade" 2-4 thousand years old?

im sure someone else can be more acurate than i am, you have too many stemmed forms to look through from your area

good luck and keep looking!!!

I am going to go out on a limb. I hope to be corrected. I think they may be Adena. The ovate an Adena blade the other a stemmed and resharpened Adena (robbins?). Here is a worn adena I have from many miles south of you.... Look similiar. Lets see what everyone thinks.
Good luck sir.

Thank you for your interest. I will be watching for more responses.
Something that I find intreguing is that they appear to me, a completely uneducated person regarding indian artifacts, to be of the same stone, same general style and both found within
a few feet of each other. Were they both lost by one person?
I am also very impressed by there uniformity. I think they are a very good quality.
I remember my dad saying that they were found in the garden. During that time the only place they had had a garden was right behind the house. To be exact, I can tell you from Google Earth that they were found at 43° 1'42.83"N 83°19'4.03"W.

you should delete your long and lat, you really dont want to give away a possible good spot! if you choose to, click on modify, and you can remove it. up to you tho

I no longer live there. The exact spot is now a septic field. The whole farm may be a shopping center in a few years.
There are possiblities of "treasures" all around that area. As a kid living there I never knew of the possibilities or how to search. But I remember things. There were also a few old coins found in the garden. I found what I always believed was a dinosaur toe bone down by the river. I also have a couple other arrowheads that were found there, but they are just ordinary looking to me.
I wish I knew then what I know now.

Nice finds! I would say Adena also. I think TnMountains hit it right on the head.
