Turner Geology Collection

Clarence Helmer Turner was a pioneering State of Missouri Geologist who had a passion for sharing his knowledge with the public.  Thanks to his daughter, Dorothy Harlan, we are able to share a portion of C.H. Turner's rock and mineral collection with you. 
Geology Jumble allows you to match the mineral sample with master specimens to see how well you know your minerals.  Fun and informative for all ages.
