Sharp....

....curves in the ice. Now, I DO realize that it's TinyTuesday and this is a bit of a stretch, however, these curves are just a very tiny part of Lake Michigan, which has a water surface of 22, 300 square miles (57, 800 sq. Kilometers), is 300 miles long and about 75 miles across.....in my mind, that makes this "tiny"!    :)))) 
Thanks to mindful_life for hosting TinyTuesday this month!
