The story behind it
Lake Athabasca is a long lake in the far north of Canada. About three quarters of it lies in Saskatchewan and one quarter in Alberta. Its biggest river, the Athabasca River, meets the Peace River in a huge wetland called the Peace–Athabasca Delta. The lake's water leaves through the Rivière des Rochers and then travels on by the Slave River and the Mackenzie River all the way to the Arctic Ocean. On the southern shore lie the Athabasca Sand Dunes, the largest active sand dunes in the world north of 58 degrees latitude: a small desert right beside a northern lake! Some dunes are about 30 metres high. The village of Fort Chipewyan began in 1788 as a fur trading post. The lake is also famous among anglers: in 1961 someone caught a record lake trout here that weighed 46.3 kilograms.
