Shaft of the abandoned Tod and Wells mine at Austintown Township, Mahoning County, Ohio. The Tod and Wells mine was a subsurface mining operation for the Sharon (No. 1) coal. The area of the mine has shale, siltstone, sandstone, conglomerate, limestone, underclay, coal and flint lithologies. Bedrock is from the Pennsylvanian Geologic Period. The photograph was taken during the summer field work of James Osborn Fuller and Myron T. Sturgeon in July 1941.
