Mare Frigoris (Sea of Cold) 1.40 E 56.00 N While lunar maria generally tend to be circular in shape, Mare Frigoris is not. It extends roughly 300 km north-south and 1,600 km east-west between Lacus Mortis and Sinus Roris, see the inlet of Image T024A. The formation of Mare Frigoris is not ascertained. Some geologists suggested that it could be part of the lava-filled depression that belongs to the outmost circumference of the gigantic Imbrium Impact; the other parts of depression including Mare Vaporum, Sinus Aestuum and perhaps, the eastern portion of Oceanus Procellarum. There is no notable crater within Mare Frigoris except Aristoteles (diameter 87 km) in the east and Harpalus (39 km) in the west.

Sinus Roris (Bay of Dew) 56.6UW 54.0UN A dark lava plain between Mare Frigoris and Oceanus Procellarum, size up to about 200 km.

Plato 9.40 W 51.60 N

Plato is a walled plain, 109 km in diameter, 1000 m in depth. Hevelius of the 17th century called it "The Great Black Lake". It is one of the darkest surface features, even in the full moon. Its lava floor looks flat and blank, but tens of tiny craterlets are detectable using big telescopes under good seeing. At Moon age of about 9 days, the eastern walls of Plato cast spiky shadows on the floor. The western walls also cast similar shadows at Moon age of about 21 days. There are two triangular landslides on Plato's rim; similar landslides also exist in Aristoteles |Map15| and Gassendi MAP 25. An oval ghost ring, nicknamed Ancient Newton, exists between the southern wall of Plato and Mons Pico. It was first noted by Schröter in 18th century while "Newton"

Scoresby 14.10 E 77.70 N

A 55-km crater with two low hills and a small crater inside the floor. Scoresby M (54 km) is a shallow crater in the south-west vicinity.

Gioja 2.00 E 83.30 N A 41-km crater. Its western rim is heavy eroded.

A 93-km walled plain connecting Gioja. It eastern and western walls are heavily eroded. Its floor is peppered with craterlets.

Peary 33.00 E 88.60 N A 73-km crater nearest to the north pole, resolvable only during favorable libration. Peary is in fact circular but looks much elongated due to extreme foreshortening. A wide portion of its southwestern circumference is opened to an unnamed feature (T240, No. 8). Part of Peary's southern floor remains in permanent shadow (S1, S2). Two sections of its rim (B1, B2) seem to be brightened during the full season of the lunar summer. This is because the Moon's axial tilt is as small as 1.50, hence the Sun illuminates Peary at grazing angles most of the time. Compare T240 with the Clementine image at right.
