It's tough identifying rocks from just a couple of pictures without some real good close-ups to show the size and nature of the mineralogy plus some basic information about hardness and density. It appears to be volcanic and - as a guess - I would say it might be in the territory of basaltic andesite.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.

Just goes to show how pictures can be misleading. It doesn't even look like the same rock in the second set of pictures. It's now clear that much of it, especially the surface coating is glassy and amorphous... so since you say it's dense and hard I would say it's probably largely composed of chalcedony.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.

I am not far north of you in Madison County, and up here a popular driveway material is slag from the mines around Jewett. It has that slightly glassy, blue color. Packs down like lava and makes a great driveway, but sadly man-made.
