What is this? Does not appear to be quartzite. Found at location on my avatar. Milk can lid for size reference. Thank you.     Same as above, but lace area wet.    |

Looks like a mix of common quartz (macrocrystalline quartz) and chalcedony (cryptocrytstalline quartz).

Grey Chert, and whats a milk can lid? A milk can lid is what goes on top of a milk can. This one is about 14" across. The rock is more like quartz than chert. The one area with layers is a little cherty. |

Please, when you ask for an ID, post relevant info upfront, if you note translucency mention it and post an image of it if possible. But from these images I don't see any translucency.
I still contend based on these images it most resembles a weathered, banded, glacially deposited, gray Chert nodule. I say this with confidence because being from the same general area with the same glacial til I have collected and seen many, many similar Chert nodules. Ok, now its attractive with its varying shades of grey color and interesting bands etc..but it is still technically a Chert rock, if you think it is possibly a macro crystalline Quartz you would need to likely break off a piece to confirm.

fuss Sorry for the confusion. The strange looking area in the 2nd photo looks like plain, gray chert. The darkest areas are a deep blue. Most of the rock is translucent, like a milky quartz. I thought it was unusual with the banding, pits and cherty area.
