This rock is about four inches long and wide and about 2 to 3 - TopicsExpress



          

This rock is about four inches long and wide and about 2 to 3 inches thick. I found it in a bucket at my aunts home in Marquette County. She often collected rocks from her fields and this was in a bucket filled with other rocks from her land. I am not educated in rocks, just learning the basics. I wonder if someone can help me identify what this is. Obviously to me, its a harder substance that formed channels and a softer substance filled the channels. The softer substance seems like sandstone to me. Thanks for any help you can give me.
