Mapping Ohio

These maps have come in awfully handy as I’m getting my bearings on Ohio’s geography, geology, and hydrology.

• Physiographic regions of Ohio
• Bedrock geology map
• Glacial map of Ohio
• Ohio 8-digit hydrologic units
• Ohio’s rivers (Figure B-1 on page 8 of the 2012 Integrated Report by Ohio EPA has more detail, but the streams aren’t labelled.)
• Ohio population map (based on 2000 Census data)
• Ohio County Map
