North America contains a huge area of plains with cool climate. There are thousands of natural and man-made lakes most of which lie in Canada and the United States. The continent covers an area of 24.7 million square kilometers with 23 countries including United States of America, Canada, Mexico, Greenland, Cuba and many small countries lie on the continent. The Great Slave lake located in Canada in the region of Northwest Territories is the deepest lake on the continent of North America at a depth of 614 meters and Crater lake at a depth of 594 meters in United states is the second deepest. The surrounding lakes have beautiful scenery and some of them are identified as National Parks.

The Great Slave Lake is the second-largest lake in the Northwest Territories of Canada, the deepest lake in North America at 614 meters, and the tenth-largest lake in the world. It is 469 km long and 20 to 203 km wide.

Great Slave Lake was put on European maps during the emergence of the fur trade towards the northwest from Hudson Bay in the mid 18th century. The name 'Great Slave' came from the Slavery Indians, one of the Athabasca tribes living on its southern shores at that time. The name was influenced by Cree disdain for this rival tribe, with whom they shared a sordid history. As the French explorers dealt directly with the Cree traders, the large lake was referred to as "Grand lac des Exclaves" which was eventually translated into English as "Great Slave Lake".
