The Great Lakes System and The Dynamic Great Lakes

The Great Lakes System  click the link

the link is to wikipedia.  Below is The Dynamic Great Lakes with what lies beneath the freshwater seas.

On the Door Peninsula

Ancient saltwater seas once covered what are now sweetwater lakes. The saltwater seas deposited limestone in layers. In the photo you can see how the limestone was formed over time in layer after layer. I took this photo on the Door Peninsula of Wisconsin. It juts out into Lake Michigan in such a way that sailors called it Death's Door due to hazardous conditions. Now it is simply called the Door Peninsula.

Read more about the Great Lakes in my book, The Dynamic Great Lakes
with information about how these lakes were formed and what lies around and under the water.

The book is widely available on the www and in bookstores.

Water is Life

Remember the story about King Midas? He wished everything he touched would turn to gold. Then he sat down at a banquet and his food turned to gold, his goblet of water turned to gold--he then understood his mistake. Water is life itself.  We can't drink gold.

Like King Midas, we should never sell our water for money. It belongs in the commons. It belongs to the eight states and two provinces--the bottom lands under the waters as well as the shores, tributaries and groundwater that feed the Great Lakes. By selling this water, the Great Lakes will shrink and their species will die.

Only 1% of this water is replenished by rain and snow.

The Dynamic Great Lakes is a primer about the Great Lakes system and its species.

The Freshwater Seas

The Great Lakes are really freshwater seas.  They contain about 18% of the fresh surface water in the U.S.  and can be treacherous for boaters and swimmers who underestimate their power.

Right now fish are migrating toward their spawning places in the lakes and in tributary streams.  Pacific salmon that were planted in the Great Lakes will die after they spawn.  Lake trout, a native species will continue to live after they spawn.

For more information about the Great Lakes and their biota, read my book, The Dynamic Great Lakes, available at bn.com, Amazon, and many independent bookstores.

Great Lakes are Freshwater Seas

Our beautiful water planet as seen from the moon. Most of the water on this planet is salt water. The freshwater seas--the five Great Lakes--need to be preserved for generations to come.
They are 18 per cent of the fresh surface water on this planet. Water is life. These lakes would lose their integrity and the living things they support if the water is sold outside of their watersheds. We should never allow them to become sold, polluted with mine wastes and other industrial byproducts. Water is too precious for that.
