Basal sliding phenomenon helps glaciers move down the valleys of the southern Alps. Basal sliding is the action of the glacier moving down across the bed because of the melting of water below the ice moving as the lubricant.
The so-called “Toledo War” had its roots in the shortcomings of 18th century geography. In 1787, Congress drafted the Northwest Ordinance, which stipulated that 260,000 square miles of territory surrounding the Great Lakes would eventually be carved into a handful of new states. Specifically, the law decreed that the border between Ohio and Michigan was to run on “an east and west line drawn through the southerly bend or extreme of Lake Michigan” until it intersected with Lake Erie. There was just one problem: the best available maps depicted Lake Michigan’s southern tip as being several miles north of its true location. As a result, the original border placed the mouth of the Maumee River and the future city of Toledo in northern Ohio rather than in southern Michigan.
