These captures of w
estern Crisium sea through the telescope,
are presented in another article:
Video by astronomical telescope-near Western Mare Crisium.
There are many present craters on this large area, and I
will only talk about features that were not discussed before.
We start with Burkhardt crater (57 km), which is located between craters Geminus (86 km), on north,
and Cleomedes on south.
Burckhardt is located on
two slightly smaller-sized
craters on the opposite sides,
producing a triple crater formation.
Burckhardt E (39 km), is covered by the southwest quadrant of Burckhardt's, while
Burckhardt F (43 km), is covered by the northwest quadrant.
Crater rim is circular,
but somewhat irregular in shape. There is a central peak near the midpoint of the crater floor.
Stucked in the western edge of the crater Cleomedes, is Tralles, and to the east of Cleomedes is the crater Delmotte (32 km), a
small crater, whose
characteristics are difficult to see because of its position.
Continue to the next photo description below, are craters Macrobius and Tisserand,
64 and 37 km, crater ray Proclus (28 km), and west of Proclus is Palus Somni ,
an area of 143 km,.
In the third picture below, there are many small craters on the surface of the sea,
but also on its edge.
Peirce crater (19 km) with Picard (23 km), are those who are most "into the sea" of
Crisium.
Picard's interior has a series of terraces, which
seismologists have attributed to a collapse of the crater floor.
The lowest point of the crater floor is about 2000 meters below its rim,
and has a small hill in the center.
Other craters located further to the edge of the sea are Yerkes (36 km), Lick (31 km), Greaves (14 km), and Glaisher crater (16 km).
Yerkes crater (36 km), it seems
interesting,
because its inside was almost completely flooded by lava,
leaving only a shallow remnant edge above the sea,
and the edge is the most visible in west. The floor has a similar albedo with the
large Crisium sea,
so Yerkes's features are not distinct by surroundings.
About craters Firmicus (56 km) and Apollonius (53 km), I
will speak in another article dedicated to them.
