Yep, there's a rather large seam of coal and it's one of the reasons that the rail came through here. It's Illinois Coal, so I'm pretty sure it's high in sulfur. The only question is if there's actually sulfur veins in it or if it's embedded in the coal which makes it all the more difficult to extract without pulverizing, etc. Still, it's better than nothing when you aren't near a volcano or other pure source.
