Lake Michigan’s Ice Formations: Part 4

Over the next few days we’ll be posting installments of an ongoing series here at the Backyard Geographer documenting winter ice formation on Lake Michigan.  For previous coverage, see parts 1 and 2 from 2009-2011, and part 3 from December of last year.

PART 4

The pictures in the series below were taken on January 11, 2013 after overnight rain. The air temperature was 50⁰F.  Daytime high temperatures have been above freezing for a week.

Even as it gives way to warm weather, the shore ice forms fantastical shapes like these delicate stingray figures that seem poised to leap into the lake.
