I had a chance to work some quartzite collected a few miles from the Sheguiandah site on Lake Huron this past summer. I think its quartzite but knaps fairly well but feels really grainy like poorly cooked Keokuk.

Heres a few more pics of all the spalls I collected including a few abo preforms I started this morning but figured I finish them later. Thanks for looking.

Very nice, I would like to work on some of that. It looks like a grainy Burlington. I am wondering what some heat treatment would do to it. If you have a good source that could be some good rock to have.
-
Some of the stuff is awful but there some fine grained material which does take heat well and it really changed the look of the rock both in color and workability. The hafted point was heat treated and came out waxy but brittle, the lighter was hafted but shot it and was intending to re-sharpen it but never got around to it. I have a source for this material now after finding a nice cut in an old decommissioned logging road but no time to collect it when I'm out that way.

Nice find and knapping.
I think you have a good source.
Beware of frost cracked surface stuff.
I don't think It's a Quartzite ???

Nice work!

Not quartzite. A grainy form of Bayport chert?

Not sure about Bayport chert but I collected it from Manitoulin Island if that helps, one thing I am certain of though as rough as it is its free :)
-
I do think it is a chert of some kind. As you say, as long as it's free and knaps, who cares, let the geologist hang a tag on it. With the glaciers having moved so much rock around, you never know what might turn up in Michigan. Some examples of Bayport chert shown below, if anyone is curious.

Clewis,
Sorry, wasn't paying attention. When you mentioned Lake Huron my mind immediately went to Port Huron, since about a million years ago I had a friend from there. I see you are talking about a site on the Ontario side and north of Port Huron. I certainly wasn't trying to cheat Canada out of half the lake! :D
I still think there may be some association between the Bayport chert and what you found, but not sure geologically how.

Aren't the deposits on Manitoulin Ancaster, or maybe that's Onandaga
-
Definitely not Onondaga, almost looks like a form of Hixton?
-
I think best describes it

The material actually looks a lot like something picked up alongside a road near Barrie, Ontario about 8 years ago. They were small very white nodules with the biggest being about 3" around. I don't know what it was but it flaked well and looked a lot like porcelain but with a smoother texture
-
man if you produced those from that then you defiantly know how to knapp. 8) good job
