New Ohio DNR guidebok examines Lake Erie geology
Columbus, OH– A new guidebook published by the Ohio Department of Natural Resources (ODNR), Division of Geological Survey offers a tour of the state’s geologically dynamic lakeshore.
"Geologic Setting and Processes along Lake Erie from Fairport Harbor to Marblehead, Ohio" (Guidebook 21), compiled by Donald E. Guy, Jr., ODNR Division of Geological Survey (retired), and Laura J. Moore, presently at the University of North Carolina – Chapel Hill, is much more than a field trip guide. It introduces a wide audience to the coastal processes that shaped and are transforming Ohio’s north shore.
Guy and Moore provide straightforward explanations of coastal processes, such as erosion, sand transport and flooding, and examine the effects of man-made shore structures on such processes. Lake levels, key weather events, historical information and environmental impacts are also considered and discussed.
The tour begins in Painesville-on-the-Lake (Lake County), where erosion has caused high bluffs to recede more than 400 feet since 1937. The guidebook then leads users to Headlands Beach State Park at Fairport Harbor and describes how the Fairport Harbor jetties affect beach width and shoreline orientation at the park and along the lakeshore east of the harbor. From there, users will continue west through 10 more publicly accessible, geologically and environmentally diverse locations, including Edgewater Park in Cleveland and Sheldon Marsh State Nature Preserve in Huron. Many of these stops represent not only classic examples of geologic processes but are some of the most recognizable landmark features along the Lake Erie coast.
Covering about 90 miles of Lake Erie shore, Guidebook 21 will be useful to anyone interested in coastal geology. Featuring more than 50 maps, diagrams and photographs, as well as detailed descriptions of each stop, the guidebook also provides a comprehensive reference for professional geologists, environmentalists, land planners and property owners. The guidebook (and tour) is also a resourceful teaching tool for earth science educators.
Geologic Setting and Processes along Lake Erie from Fairport Harbort to Marblehead, Ohio ($12 plus sales tax and shipping) is available via the online Ohio Geology Store at www.ohiogeologystore.com or by calling (614) 265-6576.
The guidebook also can be ordered from the Division of Geological Survey at 2045 Morse Road, Building C-1, Columbus, OH 43229. A compilation of other geologic field trip sites and planning materials is available for free through the division’s Educational Resources Web page.
