I’ve carried each of these patches to the Glacial Grooves on Kelleys Island, so whether you’ve been there or not, it’s a true souvenir of this geologic feature.
Each patch comes stapled to a postcard describing the landscape:
“Glaciers shapes landscapes by transporting boulders, clays, & sediments from one place to another. The weight of the ice sheet pressurizes ice into fast moving streams of water filled with these abrasive materials. Beneath the glacier these jets of water erode and gouge the bedrock with undulating, fluted grooves. Around 17,000 years ago, series of long scratches, striae, and megagrooves were carved into the limestone bedrock in the Great Lakes region. In Lake Erie, grooves exist on the lakebed, on the mainland, and on Kelleys Island.”
