3 Large Lakes In Northern Canada Meteorite Craters TOLEDO, Ohio (AP) - A glass consultant and a professor at the University of Pittsburgh says an expedition he was on this summer has found evidence that three large lakes in northern Canada are meteorite craters. Dr. Alvin J. Cohn, a consultant for the Owens-Illinois Glass Co., said that if the theory is true, one of the lakes Manicouagan Lake 600 miles north of Montreal, would be the largest meteorite crater in North America and the second largest in the world. The lake is more than 45 miles in diameter. Also studied by the group were Lac Couture, 600 to the northwest of Manucouaga and Clearwater Lake near the east coast of Judson Bay. Clearwater Lake, according to Cohen, is contained in two joined craters. One is 18 miles in diameter and the other 13 miles across. Cohen said evidence of meteorites hitting the earth are being discovered at an increasing regularity. Two of the most recent craters discovered are in Adam County, Ohio, one near Serpent Mound. That crater is four miles in diameter. They range in age from 20,000 to 250 million years. Cohen said a meteorite one mile in diameter striking the earth would make a crater 45 miles across. The impact would knock down trees and houses over hundreds of square miles. Cohen, in an interview with Toledo Blade Science Editor Ray Bruner, said he and the other scientists with him believe the basnis for the lakes were made by meteorites because of the shape. He said aerial photos showed part of the shoreline may have been formed by the impact of the meteorite. Cohen said if it is a crater it was formed by termendous impact because the curvature of the shoreline suggest the existence of a crater more than 250 miles across.
