Material ID

[Sparks317]

Does anyone recognize this material? It seems rather abundant in my area (central Indiana) I’ve found hunks, chunks, spalls and flakes and today I found this point made from the stuff.

Could be Flint Ridge or some type of Pudding Stone... Congrats on your rescue!

Looks like Harrodsburg chert

It looks like muldraugh chert to me.

I’m in central Indiana too, and have found a little pieces of stuff that looks like that before around my property by a creek. If it’s the same stuff, I wondered if it was agate because it’s got a glossy, small crystal grain, and parts of it are transparent. I don’t know my cherts very well though.

Chert ID is tricky for me, since there are so many varieties that overlap and each one can come in a range of colors and patterns. But it seems there are a few varieties that dominate each area. Have you identified any of the other common cherts around here, Sparks?

There’s one type I see pretty commonly around waterways, often see pieces of something that at one point were worked into sort of a thick hoe, preform, or hand axe shape, and usually don’t seem to preserve well, but are brown, fine-grained, continuous boring color, but usually more chalky than super glossy. it must’ve been an important material, and seems fairly common, though I’ve never found a biface out of it so maybe it has limitations. Have you seen anything like that? Any idea what it is?

Hay Sparks I found a piece of that last month in Bloomington. I posted it and this is what gregzybola said "The spotted piece is probably Harrodsburg". Mine looks just like what you found.
