Smitty the Mastodont


Mastodont Bones Found



In l985, the gigantic bones of a mastodont were found in

 Grandville, a city in West Michigan. A family digging the

foundation of a new house reported the find to Dr. Richard

Flanders, an anthropologist at Grand Valley State University

and Dr. Flanders along with his anthropology students began

the task of digging up the skeleton of the Ice Age animal

very carefully so that none of the bones would be lost or

destroyed in the process.

After all the bones had been carefully reassembled, they

could learn a great deal about Smitty, a name the students

gave to the ancient animal. Smitty weighed as much as a

school bus and his huge tusks were supported by a very

powerful neck.

Some parts of Smitty were missing, the brain and the

legs. They wondered if Smitty might have been hunted and

then killed by paleo indians because these would have been

the choice cuts of meat. Professor Flanders took some of the

bones to a butcher for his opinion. Flanders suspected that

the animal had been butchered for its meat. The butcher told

him that it looked to him as if the bones had been butchered

in the same way butchers still cut meat today.

The place where Smitty was found also led Dr. Flanders

and his students to believe that the mastodont had been

driven into a pit by a number of hunters and their dogs where

he could be killed with stone weapons.

Although the mastodonts and their larger relatives the

mammoths were numerous at the end of the Ice Age and

quite a few of their bones have been found in the Great

Lakes basin, they disappeared from the face of the Earth

along with the other mega sized animals.

Great Lakes Water Levels are Down

The Great Lakes water levels are down.  With so much water it does not seem possible that people in the Great Lakes basin need to conserve water, and yet it is becoming necessary.

 According to Alan Steinman, PhD and director of Grand Valley State University’s Annis Water Resources Institute in Muskegon, dredging in the St. Clair River by the U.S. Army Corps of Engineers has lowered water levels by a couple of inches. Dredging opened the drain to cause the lake water to run out to the Atlantic at a faster pace.  Other causes of lower water is evaporation—a hot summer—little rain and snow and little or no ice cover in the winter.  Global warming is causing great changes in the Great Lakes.  Lower water levels dry up wetlands around the lakes.  These areas are nurseries for fish and birds and serve to filter out pollutants.  Boaters may find themselves high and dry. 

So for those living in the Great Lakes watersheds, don’t waste water.  Think of ways to conserve.

The Great Lakes Basin

This chart is from Seagrant.  It shows the Great Lakes watershed in green and the five Great Lakes in blue.  Also shown in this freshwater system are Lake Nipigon north of Lake Superior and Lake St. Clair between Lake Huron and Lake Erie.  Although large, these lakes are not called Great Lakes.  Starting from Lake Superior some say is shaped like a wolf's head, the water flows into Lake Michigan and Lake Huron, then into Lake St. Clair and Lake Erie.  The freshwater then takes a tremendous plunge over Niagara Falls into Lake Ontario and from there it flows out the St. Lawrence River  until it reaches the Atlantic Ocean.  Also seen on this chart are the states in the United States and the provinces in Canada surrounding the Great Lakes.  Canada and the U.S. share this mighty freshwater system. 

Read more about the Great Lakes in my critically acclaimed  book, The Dynamic Great Lakes Now available from the Amazon.com Kindle for $9.95, Barnes & Noble in paperback and many other fine bookstores.
