About the East Harbor State Park Glacial Grooves

All of the Great Lakes were carved out by glacial activity.  As the glaciers retreated, the basins carved out were filled with water – resulting in the five Great Lakes.  The glaciers also left evidence behind in the forms of glacial grooves and striations in the bedrock in the Lake Erie region.

The glacial grooves at East Harbor State Park are fairly small, but still impressive when you consider the sheer force of nature that formed them and how long ago that occurred.   The striations are shallow, but clearly defined.

Glacial grooves definition:

Have no idea what glacial grooves are?  We didn’t either until our trip to Kelley’s Island!  The glacial grooves definition is this

Glacial grooves are sets of parallel furrows which have been ground out of rock surfaces by boulders lodged in the moving sole of a glacier or ice sheet. The rock surfaces have often been polished by finer debris.

There is no signage at the actual glacial grooves site.  At first glance it just looks like a slab of concrete that nature is slowly taking back.  There is a small covered seating area with an informational sign about East Harbor just in front of the grooves.  (See the informational sign I included earlier in this post.)
