Lake Michigan, the only Great Lake that lies entirely within the United States, was formed during the ice age of the Glaciers. Located on the Southern tip of the lake, Indiana can claim only a scant 35 miles of Lake Michigan's shoreline. Michigan City, Indiana, located on the south-eastern corner, is well known for it's soft, sandy beaches and ample watersports activity on Lake Michigan.

But just what is this fascinating "stuff" called sand under our feet? We walk on it, stand on it, sit on it, play on it, lay on it, dig in it, and usually get some stuck behind our ears to find it's way to the car or home. And, under proper conditions, we have the rare feature known as "Singing Sands", or the odd "Musical Squeak".

If you are curious about the beach sand, enjoy this microscopic image of Lake Michigan sand. This is sand taken directly from the Washington Park Beach at Michigan City, Indiana. (The area to the left in the above photo.)
