On March first, I decided to rent a car and drive south. I'm finishing school in Chicago in May and am preparing to move west, so I really had no time to waste collecting Illinois. I hit three spots - one limestone road cut and one shale road cut in Oglesby, IL and the Mazon pits on the way back up to the city. I'm grateful to a few members for their posts and message replies regarding the road cuts, I couldn't have done this trip without them. I took off at 7 AM towards Oglesby. Here's the map, if you look at Oglesby on Google maps the location here should come together: Once you're there, it's basically a free for all. You are searching through the LaSalle Limestone Member of the Bond Formation which houses Pennsylvanian fossils. There are brachiopods everywhere you look which crumble down the hill and expose new matrix. Here are some of the Linoproductus I took home: I'll make another post for the second road cut
