Rippled Rock River Reflections

"Fifteen thousand years ago during the Wisconsin Glaciation, ice covered the Rock River Basin. The continental glacier sculptured a rolling landscape that supported thickly wooded lands interspersed with oak-savannah prairies, large wetland complexes and numerous large and small lakes. Today, threading through this rich, ecologically diverse landscape is the Rock River and its major tributaries, the Crawfish, Beaver Dam, Oconomowoc, Bark, and Yahara rivers, and Turtle Creek.

The Rock River Basin covers 3,777 square miles and is located in ten counties: most of Dodge, Dane, Rock and Jefferson and parts of Washington, Fond du Lac, Walworth, Columbia, Waukesha and Green Lake counties.

Wisconsin archaeological records indicate that areas of the Rock River Basin were inhabited by the Woodland culture 3000 years ago. These people were 'mound builders' who left their mark on the landscape near waterways by building effigy mounds shaped in the forms of birds and animals. At one time the mounds were prolific, numbering more than 1,500 in Jefferson County alone."

Clear, Superior H2O

Clear, Superior H2O, originally uploaded by jw_creations.

"Not only is Lake Superior the largest of the Great Lakes, it also has the largest surface area of any freshwater lake in the world. It contains almost 3,000 cubic miles of water, an amount that could fill all the other Great Lakes plus three additional Lake Eries. With an average depth approaching 500 feet, Superior also is the coldest and deepest (1,332 feet) of the Great Lakes. The lake stretches approximately 350 miles from west to east, and 160 miles north to south, with a shoreline almost 2,800 miles long. The drainage basin, totaling 49,300 square miles, encompasses parts of Michigan, Minnesota, Wisconsin and Ontario. Most of the Superior basin is sparsely populated, and heavily forested, with little agriculture because of a cool climate and poor soils."
