FORMATION OF THE GREAT LAKES, PAGE 8

10/16/2022

Lake Superior is the 2nd largest freshwater lake in the world if one wants to argue that the Caspian is a lake or a sea. At 31,700 square miles, a deep point at 1,332′, and an average depth of 483′, Superior contains about 10% of all the fresh water on the earth, ignoring glaciers. It is a body of water that is theorized of having its shape carved out by glacier action of the ice ages. The reason for this logic is the striations, or scraping marks, on the rock surfaces at the bottom of these lakes. Someone has watched a bulldozer dig down but has not given much thought to how the glaciers remove the material from down below. In real life, dump trucks and scrapers move the spoil elsewhere.  Regular glaciers plow huge quantities of rock and debris from mountains and move it downhill, out in front of the glacier. The key here is gravity. Matter moves downhill from gravity or uphill through uplift from underneath.  In the formation of the Great Lakes, the consensus is that glaciers began in Canada and scraped below grade into limestone, or the Canadian Shield, to excavate this material. The question becomes: why didn’t they dig up Canada everywhere and turn the whole thing into a giant Hudson Bay? Why just the Great Lake Basin? Their proof is those scrape marks. So what if a giant object smashed into earth in the present State of Michigan and blew a large hole in the ground that allowed later glaciers to enter into and scrape the existing crater floor? The ejecta from this huge hit would scatter in a northwest direction, punching thousands of holes into the Ontario Canadian Shield. All this energy from the impact would get directed into the mantle and cause stresses that would disrupt the stability of the surface in a short period of time. This theory surmises that this enormous jet of thrust created a rift or opening in the earth that created Lake Superior. Lava flows, ejected material, and mountain forming stresses are all here, visible all around Lake Superior.   

This Ice Age depiction is why scientists surmised that in just the Great Lakes region, glaciers excavated and removed the spoil below sea level and created the 5 unique Great Lakes: but nowhere else.
