Hidden Ohio Map and Guide is a comprehensive paranormal travel guide in map form published in 2007 that documents many of the haunted locations across the state of Ohio as well as parts of Michigan, Kentucky, and West Virginia. Other unusual activities and places are also pinpointed on the map including strange creature sightings, ancient Native American earthworks, and UFO sightings. Besides the paranormal locations, many other items are on the map including state parks, preserves, wildlife areas, Amish areas, ecological regions, state highways, U.S. Routes, Interstates, place names, and physical features. On the reverse side of the map, there is an alphabetical list of each haunted site with a description of the event as well as exact directions. The map was created by Jeffrey R. Craig, an Ohio cartographer and Geography Instructor at Northern Kentucky University. A 2nd edition of the map was produced in 2009 with some new updates and illustrations added by Cincinnati area artist, Oliver Meinderding.
