ABANDONED-UNDERGROUND- MINE MAPS

The location and extent of abandoned underground mines in Ohio have been plotted at a scale of 1:24,000 (1 inch equals 2,000 feet) on U.S. Geological Survey 7.5-minute topographic quadrangle mylar bases (black and white). These maps show available information on mine outline, mine identification number, relation to drainage, and types and locations of mine entries and air or pumping shafts. The information on these maps is based largely upon original mine maps. Although the maps are updated as additional information becomes available, the Geological Survey makes no affirmations concerning the accuracy and completeness of the information on these maps. Copies of the abandoned-underground-mine-map quadrangles are $4.00 each.
 
County index maps at a scale of 1 inch equals about 1 mile (1:62,500) have been prepared from reduced and composited copies of the 1:24,000 quadrangles.
