Walter, do you know the name of the rock formation that is being quarried? it must be incredibly pure and free of things like shale partings and chert lenses.

It's part of the Salem limestone formation, which extends through Illinois, Indiana, Kentucky, and Missouri. There is a stretch of the formation around Bedford and Bloomington Indiana with is very pure, very deep but starts close to the surface (so it's accessible and consistent for a great depth), and wide.

Very interesting Walter, thanks. Sorry to bother you and and the rest of the forum with such a geeky question, but my day job is geologist so I was curious. I will research it a little now that I know the formation and the location.
