The '''Great Lakes''' are a series of five lakes located mostly in between the [[United States]] and [[Canada]]in north central [[North America]]. Together they are the largest group of fresh water lakes on Earth. The Great Lakes include:
* [[Lake Superior]]
* [[Lake Michigan]] - the only Great Lake located entirely in the USA.
* [[Lake Huron]]
* [[Lake Ontario]]
* [[Lake Erie]]
Although several other large lakes and islands make up part of the Great Lakes System. They drain through the Saint Lawrence river into the Gulf of Saint Lawrence. In 1959 the Saint Lawrence Seaway opened the Great Lakes to Ocean going boats, allowing travel well into the heart of North America. Although the Great Lakes themselves had been connected before this with a series of canals.
Because of the large size of the lakes many of the larger cities experience lake effect snow, where westerly winds capture moisture over the unfrozen lakes and when cooled over the land, heavy snows can fall. Additionally the lakes can moderate the warm temperatures in the summer, and release the heat in the fall.
