The following post is the latest installment of an ongoing series here at the Backyard Geographer documenting seasonal ice formations on Lake Michigan. For previous coverage, see parts 1 and 2 from 2009-2011, and parts 3, 4, 5, and 6 from winter 2012-2013.
The following series of pictures was taken on January 27, 2013. The air temperature is in the high 20s after similar conditions yesterday. Lake Michigan water temperature is about 37⁰F.
Even with air temperatures below freezing, water temperatures above freezing are winning the battle at the shoreline. The impressive 12-foot tall ridge at the waterline only three days ago has melted back to leave these remnants stranded offshore by open water.
Signs of ice demise are everywhere. The right side of this ice volcano is collapsing as relatively warm water melts the ice walls of the volcano’s plumbing system. One slab has collapsed forming the window through which the lake can be seen. The large block forming the ice bridge seems on the brink of collapse due to developing cracks.
Temperatures are forecast to reach well into the 50s in a few days. Time will tell if any ice remain until the next cold snap predicted for later in the week.
