Last evening I did a bit more research on Arnold Tuma, son of Wencel and Anna (Jindra) Tuma.  He along with his brothers moved from Wisconsin out to Montana and became mustard seed farmers.  Arnold and his wife had two children.  One of them, Gene, was a geology teacher.  Gene Tuma was instrumental in the Montana Strip Mining Reclamation Act back in the 60s.  The federal law passed in 1977 requiries that lands strip mined for coal have to be reclaimed.  In Montana, big coal companies continue to delay reclaiming the land that has been impacted by strip mining.  You can see more about the Arnold Tuma family here.
