About this collection

The Indiana Natural Resources Maps digital collection depict natural gas, coal, petroleum deposits as well as the locations of stone quarries, pipelines, and wells from the 1880s to the early 1900s.

 

The natural gas geological maps mark the beginning of active drilling and production of natural gas in the Trenton Gas Field in northeast Indiana and were produced by the Indiana Department of Geology and Natural Resources. These maps were produced to accompany the Annual Report of the State Supervisor of Natural Gas, which are available in the General Collection of University Libraries.
