- There is snow since this is a
winter.
It may be true colors,
but it looks a little overly grey.
The view is oblique and to the west.
- The Manicouagan crater
is in Quebec,
Canada, ∼ 200 km north of
Baie-Comeau,
Quebec---i.e., the middle of nowhere.
The area of the Manicouagan crater
is rugged and heavily timbered and is in the
Canadian Shield.
- The Manicouagan crater
is multi-ring crater
of ∼ 100 km in diameter.
The visible part
is ∼ 72 km in diameter
(see Wikipedia:
Manicouagan Reservoir: Manicouagan impact crater).
The Manicouagan crater is the 6th largest
confirmed impact crater
on Earth.
- The Manicouagan crater is one of the
more obvious Earth
impact crater.
For most impact craters, you'd need
some authority to tell you they were there.
- The annular lake seen in the image is
Manicouagan Reservoir
which has a diameter.
of ∼ 70 km and may be a depression between two rings of
the multi-ring crater,
but Wikipedia is NOT saying.
The island
formed by
Manicouagan Reservoir
is Rene-Levasseur Island.
Manicouagan Reservoir
is drained at the south end by
Manicouagan River
which flows south ∼ 200 km and empties into the
Saint Lawrence River
not far from it becomes the
Gulf of Saint Lawrence.
- The crater is 214(1) Myr old
(thus formed in the
Triassic (252.2(5)--201.3(2) Myr BP).
The impactor is believed to
be an asteroid
of ∼ 5 km in size scale.
- Mount Babel
(peak 952 m above sea level)
is believed to be the
central peak
of the crater
which is also then a
central-peak crater.
- The crater
has been heavily eroded particularly by
glaciers
during the
Quaternary glaciation (AKA the current ice age).
