caveman2533:
You may have some harvester chert also. It tends to be dryer, not as silicified and will often have concentric rings like your picture, and is more nodular.. Again tho check your geological reports for formations locations.

Stringman:
That looks more like harvester than Burlington, but I'm sure the 2 are closely associated.

Use this with the pdf and you should find the answer you are looking for.
