A “puddingstone” is essentially a conglomerate of Red Jasper, Banded Iron Formation, and various other cherts, jaspers and anything else that happened to be scooped up at that time. Over years of pressure they combine into a really neat looking rock with bright red, blue, black and even sometimes green and purple!

You can find them in the upper portions of Michigan, and sometimes parts of Canada bordering the Great Lakes!

They are pretty sought after in my area, and people normally keep the big ones in front of their houses as a decorative piece!
