On my Sunday exploration, I came across a cliff that exposed something I had never seen before. These specimens were in a very narrow band (4 inches thick) and the hard limestone reminded me of Maquoketa as opposed to Galena. They have a spongish look to it but they also remind me of a recepticulite, similar to Tetragonis sulcata. I forgot my size marker. These are about thumb size if you have short stubby thumbs like me!!
