The ODNR Division of Geological Survey has been researching and documenting Ohio geology since 1837. Since that time, it has released thousands of geologic maps, technical reports, poster presentations, educational resources, and other products. Finding a document can be a challenge for those interested in publications about specific geologic features or areas of the state.
