Lake Erie Close-up

Although most of the Great Lakes of North America (from left to right, Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario) appear mostly sediment free, Lake Erie shows multi-colored swirls of sediment as spring begins after a nearly iceless winter. The smaller Lake St. Clair can be observed between Lakes Erie and Huron, also filled with multicolored sediments.

This winter showed warmer than normal temperatures in the Great Lakes Region. Reports indicate that temperatures around all five of the Great Lakes averaged around 5 ° F higher than normal since November 2011. Only 5% of the lakes were covered by ice in mid-February, and Lake Eries water temperatures in late March were reported at 39 °F, equal to the warmest water temperature ever measured there at this time of year.
