FORMATION OF THE GREAT LAKES, PAGE 16

11/6/2022

A high energy hit from a meteorite, or comet, or combination of the 2 can impart a huge amount of energy into its target. In this case, our home planet, Earth. If it is a solid, rocky object, it imparts a distinct type of result, known as a complex crater with variables, that hinges on the earth’s and the impactor’s composition, speed, and direction. If it is a large mass of ice (comet), which will flash to a gas in the ensuing heat buildup from atmospheric friction and strike hard rock, then another type of crater will form. If the impactor’s icy trajectory aims for an ocean or sea, still another type of crater will evolve. Solid, liquid, and gas are all variables that will dictate the results. An impactor’s shape, that later fills in with water, will change immensely over eons of time. When explaining an example, such as Reindeer or the Great Bear Lake, many changes have occurred since the collision. Deep Bay on the south end of Reindeer Lake is the actual impact site, while Gow Lake, just west of there, is another collision zone. Glaciers, pent up internal forces, and weather rearrange the landscape into lakes that change with time. A puzzle shaped piece that looks like the Great Bear Lake did not hit the Earth in 1 similar shaped chunk. The deepest part of that lake is the original impact sites, and that the forces mentioned above will modify the surrounding terrain into what we are now observing. In the future, these lakes will morph into other shapes as dynamic forces erode, upheave, and continuously change its shorelines, like the oils in a lava lamp but at a much slower pace. The major difference between the Moon and Earth are the 2 forces on Earth that act on the planet’s surface from above and below. Tectonic forces and weather patterns that constantly mutate the Earth’s surface, eradicate much evidence of the original impact sites. These factors need to be understood so that theories that can better explain what we are seeing can be brought to light. 

Deep Bay on the southern part of Reindeer Lake that gives the lake its 720′ depth.
The Great Bear Lake in the Northwest Territories of Canada. The black spot on the eastern end is the 1,463′ deep spot of this lake.
