Manicouagan Reservoir (also Lake Manicouagan / mænɪkwɑːɡən, - ɡɒ̃ /) is an annular lake in central Quebec, Canada, covering an area of 1,942 km 2 (750 sq mi). The lake island in its centre is known as René-Levasseur Island, and its highest point is Mount Babel. The structure was created 214 (±1) million years ago, in the Late ...
René-Levasseur Island is a large island in the centre of Lake Manicouagan in Quebec, Canada. Its highest peak is Mount Babel, at 952 m (3,123 feet), which is contained in the Louis-Babel Ecological Reserve. With a total area of 2,020 km 2 (and a diameter of 50.7 km), the island is larger in area than the annular lake in which it is situated.
Mount Babel is the central peak of the Manicouagan impact structure and was formed by the rebound of the crust after the impact of a meteor 210 million years ago. The mountain and reservoir are of particular interest to geologists due to the shock metamorphosis it endured. [4]
Impact crater lake. A satellite photograph of the Siljan Ring. Lake Siljan is a large part of the southwest edge of the much-eroded crater. An impact crater lake is a lake inside a depression caused by the impact of a meteor. It is also known as an annular lake in cases where the water body is shaped like a ring, as many impact crater lakes are.
The Decorah crater has been conjectured as being part of the Ordovician meteor event. [346] [better source needed] Several twin impacts have been proposed, such as the Rubielos de la Cérida and Azuara (30–40 Ma), [347] Cerro Jarau and Piratininga (c. 117 Ma), [73] and Warburton East and West (300–360 Ma).

The Daniel-Johnson dam (French: Barrage Daniel-Johnson), formerly known as Manic-5, is a multiple-arch buttress dam on the Manicouagan River that creates the annular Manicouagan Reservoir. The dam is composed of 14 buttresses and 13 arches and is 214 km (133 mi) north of Baie-Comeau in Quebec, Canada. The dam was constructed between 1959 and ...
With an area of 23,540 hectares, which makes it - by far - the largest of the entire Quebec network, the Louis-Babel Ecological Reserve occupies Mount Babel, in the northern part of the René-Levasseur Island (Manicouagan Reservoir). It is located in unorganized territory of the Regional County Municipality of Manicouagan.
It could just be an ancient discovery. Joël Lapointe from Quebec, Canada, was investigating the Côte-Nord region ahead of a camping trip using Google Maps when he found what could be a crater ...
