NEW ELEVATION MAP HIGHLIGHTING TOPOGRAPHIC FEATURES OF OHIO
NOW AVAILABLE FROM THE OHIO DEPARTMENT OF NATURAL RESOURCES
COLUMBUS, OH -- A new, shaded elevation map of Ohio that dramatically depicts Ohio's hills, valleys and plains, as well as the depths of Lake Erie, is now available from the Ohio Department of Natural Resources (ODNR). The full-color, wall-size map was digitally produced by the ODNR Division of Geological Survey.
Many of Ohio's landscape features that have influenced the state's industry, agriculture, and cultural settlement can be clearly seen on the map. These features include the southern boundary of the Ice Age glaciers, which covered nearly three-fourths of the state; chains of small, irregular hills deposited by the last glacier as it retreated from the state about 15,000 years ago; a portion of the ancient Teays River valley in south-central Ohio; and the flat plains of northwestern Ohio, which were once the lake bed beneath former, higher stages of Lake Erie.
The Bellefontaine Outlier in west-central Ohio, which includes the highest point in Ohio (Campbell Hill; elevation 1,549 feet), stands out dramatically on the map. Untouched by the glaciers, the bedrock hills of southeastern Ohio are a sharp contrast to the glaciated portion of the state.
A page-size version of the Shaded elevation map of Ohio is available for viewing or downloading from the ODNR web page at ohiodnr.com/geosurvey (map in .pdf format).
The wall-size map is offered in two different color options-one using bold spectral colors to emphasize elevation contrasts, and the other using earth-tone hues to reflect the state's natural appearance from space. Copies of the detailed, wall-size version of the map may be ordered (specify "spectral" or "earth-tone coloration" preference) for $10 plus $3.08 tax and mailing (add $1.50 for mailing a rolled copy) from the ODNR Division of Geological Survey, 4383 Fountain Square Drive, Columbus, OH 43224-1362, telephone: 614-265-6576.
