Geoff, That is Fire Agate. The dark spot on the first pic has the potential for Fire if you ask me. steve

If that really is from NW Illinois/SW Wisconsin, then I'd say it's ordinary botryoidal agate. I've found it in limestone in SE Minnesota. That whole area, including NE Iowa, is called the driftless region, and it's all more or less the same geology.

Sure looks like fire agate to me as well.

I'll have to start looking for fire agate the next time I'm in the driftless region then.

That sure looks like the botryoidal agate found all over SW AZ with little to no fire. Still looking. Don
