This is my second entry in the Spearfish Canyon Diorama build for the South Dakota Railraod Museum in Hill City South Dakota. In this second entry i have been busy placing molds with 20 Min. sheetrock mud.  After about 30 min. I peel the mold off and the mud is still soft enough to take some tools a shape the cast to blend in with the mold next to it. it is a slow process but is very real looking when complete. The TV in the back ground has a photo of Bridal viel falls in Spearfish canyon. THe falls will be on this end. I will continue to put up photos as i progress.The minning cage at the end photo was 3d printed by me the model i drew from a sketch of a mine cage used in the Black Hlls.
