More History Revealed at the Beach

On Lake Michigan’s Left Coast, one never knows what she will find at the beach. One remarkable phenomenon is the dramatic rise of the water itself.

Lake Michigan and Lake Huron act as one lake due to their connection at the Straits of Mackinac. Lakes Michigan and Huron are expected to be nine inches higher in March 2018 compared to March 2017. That would be a significantly higher start to the seasonal lake level rise, which usually starts in March or April.

Add these nine inches to the water levels that last spring were the highest of the last twenty years, and you have a coastline that constantly changes, a beach that continually reveals different eras of Lake Michigan’s past. This spring, rounded pebbles from glacial till include ancient jasper, basalt, shale, granite, and chert.
