I hope you're not serious and if you are how could you not know what that is? If you are then my apologies. Asphalt, that stuff you drive or walk on nearly every day.
Take some time to learn what is, Arrowheads.com is a great place for that as well as all that is available on the internet.Searching the fields of NW Indiana and SW Michigan

Looks like conglomerate to me too. Bitumen is a naturally occurring asphalt which was utilized by Native Americans as a sealer for pottery and a adhesive for other purposes. Was it found in an area where you found other artifacts? I am assuming the first photo is the cross section from where you cut it.TN formerly CT Visit our store http://stores.arrowheads.com/store.p...m-Trading-Post

In CA we had stuff called asphaltum oozing out of various locations. It was used to plug the holes in an abalone shell to make a plate and as an adhesive among other uses. You can see some of it on artifacts in the bodega bay anthology article on here. Black pitch like stuff. An old timer I know had some of it in a small bowl he found and mistook it for an unnecessary mess and cleaned it out. Later an archeologist, seeing what residue was left and hearing what had had been there originally, explained to him the significance of finding a bowl with all that material still in it.

That's not actually a conglomerate. Geologically, the term refers exclusively to sedimentary rocks where the clasts within the matrix are largely rounded or sub-rounded. When the clasts are mainly angular (which is very much the case here) the rock is a breccia, not a conglomerate. Breccias can be sedimentary, tectonic, landslide/collapse/impact-related or volcanic/igneous in origin.I keep six honest serving-men (they taught me all I knew); Their names are What and Why and When and How and Where and Who.
