BRLNDOBLOG Manicouagan Crater Lake

Manicouagan Reservoir (also Lake Manicouagan) 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. Manicouagan Crater was formed 214 million years ago, near the end of the Triassic Period, when an asteroid 5 kilometers (3 miles) wide struck what is now Canada. Today, the remnants of the crater are made visible by water and, sometimes, ice. The crater is a multiple-ring structure about 100 kilometers (60 miles) across, with its 70 kilometer (40 mile) diameter inner ring as its most prominent feature; it contains a 70 kilometer (40 mile) diameter annular lake, the Manicouagan Reservoir, surrounding an inner island plateau, René-Levasseur Island. The Manicouagan crater is one of the oldest known impact craters. It is in the Côte-Nord region of Québec, Canada. [1] It was caused by the impact of a 5 km (3 mi) diameter asteroid about 215.5 million years ago, [2] in the Upper Triassic. [3] The crater is a multiple-ring structure about 100 km (60 mi) across.

Manicouagan Crater Series 'Largest meteorite craters on Earth

Lake Manicouagan is actually a reservoir, part of a hydroelectric power system that powers countless nearby homes. And while it's not unusual for a reservoir to be strangely shaped and out of. Manicouagan Crater, located in Canadian province of Québec, is one of the Earth's oldest and the most visible impact craters. Manicouagan Crater was formed by an asteroid strike over 214 million years ago. Like a pebble creating ripples when dropped into water, the crater has concentric rings formed by shock waves transmitted by the impact. Stocktrek/Getty Images There are roughly 180 known impact craters worldwide and fully a third of them—including some of the biggest—are located in North America. These massive blast zones were. The drowned lake is a 60-km long arc-shaped basin lying within the Manicouagan impact crater, the so-called 'Eye of Québec'. This dataset unravels the geomorphology and the late Quaternary environmental history of one of the deepest lakes in North America, which reached a natural depth > 320 m prior to the impoundment (> 100 m below modern sea level).

Manicouagan Reservoir in Quebec marks the site of an impact crater

The Manicouagan Reservoir, 1,942 km 2, elevation 360 m, is located in southeastern Quebec, about 140 km from the Labrador border. The second-largest natural lake in Quebec, it was created by a meteorite millions of years ago. The name "Manicouagan" is possibly of Innu origin and might mean "where there is bark" (for canoe making). Today Lake Manicouagan serves as a reservoir and is one of Quebec's most important regions for Atlantic salmon fishing. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. Manicouagan Reservoir Crater Around 214 million years ago, an asteroid about 5 kilometers (3 miles) in diameter slammed into what is now Quebec, Canada, creating a crater about 100 kilometers (60 miles) across. The impact caused a shock wave and air blast that would have killed plants and animals within at least 500 kilometers (310 miles). Lake Manicouagan is a reservoir and crater lake situated over 700 kilometers north of Quebéc City. It was formed 214 million years ago by a massive meteor st.

Carved out by an asteroid strike some 214 million years ago, this crater in Quebec, Canada is known to be one of the oldest and largest impact craters on. Lake Manicouagan in northern Quebec, Canada, surrounds the central uplift of the impact structure, which is about 70 kilometers in diameter and is composed of impact-brecciated (relatively large pieces of rock embedded in finer grained material) rock.
