Mystery Fossils Found Wintertime Lake Michigan Beach

HPIM2894

Winter 2010/2011

Most years, Lake Michigan’s wave action and chilling temperatures pushes ice and snow into huge mounds over the shoreline as high as twenty feet (shown above). In order to actually see the big lake you have to climb the mounds without falling in. Danger lurks around those edges where people can and have fallen through.

It’s January 2013 and the second consecutive season where the sand is left bare of winter’s icy layers; which I can’t stress enough how extremely rare that is. Looking towards the horizon over Lake Michigan, you would normally see a frozen tundra of stillness. Not this year. Compare the photo above taken winter 2010/2011 from the photo below taken winter 2012/2013.

Case in point; due to the season’s whirling winds, minus the layers of snow, and less tourist traffic, fossils are more exposed from the continuous movement of sand. Below, are several interesting samples of fossils I found on Oval Beach, Saugatuck, MI (USA) winter 2012/2013. I haven’t been able to fully identify these species partly due to their smoothed surfaces, so please feel free to make suggestions. I have provided a few best guesses.
