The Fall and Spring classes (2001-2002) of Earth Science proposed to the state legislature a state mineral, RHODOCHROSITE.


We, the Earth Science class, wrote a letter to our Representative Carl Miller proposing the mineral and asking him for his support.  He has subsequently written and presented a bill before the Committee of Agriculture, Livestock, and Natural Resources (February 27th), where it received unanimous approval (10-0).
