These systems consist of roughly 60% of water. If they are not 100% water, then what are they? The answer is humans. Humans have an astonishing impact on how Michigan shapes itself. Manufactured objects, such as dams, and reservoirs, can create a stronger flow or cut of a certain river and direct it in a different direction. Man has become too powerful for his own good. Nature has its way of working to find equilibrium and man keeps disrupting this balance. They may have avoided some disasters but ultimately have caused more. Between glaciers, lakes, rivers, and man, we have a recipe for how Michigan has become the wonderful shape and state it is today.
When you hear the word glaciers, what do you think of? North and south poles? When we think of glaciers, we have to think of everything that glaciers have done to shape the land we live on today. Just over 10,000 years ago, there was still glacier activity in Lake Superior. Roughly 35,000 years ago, the Wisconsin Ice Sheet was reaching down to the southern counties in Michigan (Berquist). This gives us perspective of how long it takes glaciers to move and melt. It took 25,000 years for one sheet of ice to move across the state of
