Coal mines in the Green River Valley were not operated commercially but used as a support activity for the main economic bases, the ranching and oil industries.  Ranchers first used coal in their forges and later for heating homes and cooking.  When the oil industry first boomed, coal was used to supply power to the equipment. Jonita Sommers, who was the project director, researched and collected history on the mines from Fontenelle Creek to Little Granite Creek.  Ann Noble was the humanities scholar on this project which was partially funded by a grant from the Wyoming Humanities Council.
