How Fast Can a Shoreline Change?

Ohio’s Lake Erie shoreline consists of wetlands, low bluffs, and gently sloping shore in the western one-third of the state and glacial till and soft shale bluffs in the eastern two-thirds of the state. The rate of shore erosion is affected by the kind of land and rock materials and the use of protective structures. Use map reading skills to recognize some shoreline features on aerial photos, observe changes in a shoreline over time, and observe the effects of shoreline devices on rates of erosion.
