A colder than
normal North American winter saw the entire surface areas of Lakes
Superior, Huron, and Erie frozen over for the first time in years.
The cold has delayed the opening of the St. Lawrence Seaway and
will likely delay the start of the growing season near the Great
Lakes shorelines. Although the open surface waters of Lake Michigan
did not freeze this season, the southern portion experienced a higher
than normal amount of ice. Winds and currents drove broken pieces
of ice from the north to the south.
taken from the International Space Station shows a number of large
pieces of ice collected along and just off the shoreline southwest
of Benton Harbor, Mich. Smaller pieces trail northward offshore
from Chicago, Ill. Note the ice accumulation along the entire eastern
shoreline of Lake Michigan as well as the wind-driven lake-effect
snow cover over the western half of the lower Michigan Peninsula.
