Rock Elm Crater, Wisconsin, USA – (diameter : 6km wide, age : 505m years)
This is another locality that is poorly distributed and is rarely offered on the collector market. It is a slice of shale material that filled the crater. In almost 20 years of collecting, I had never heard of this crater and had never seen a specimen of it until now.
This piece is an unpolished slice that weighs approx. 11 grams.
Refer to the photos. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. Your purchase will include an ID label.
