Tags: Crater.
Gärtner is the lava-flooded remnant of a crater in the northeast part of the Moon. It is located on the northern edge of the Mare Frigoris. The southern half of the formation is completely missing and Gärtner forms a semi-circular basin along the edges of the lunar mare. To the north lies the crater Democritus.The surviving parts of the crater rim are heavily worn and eroded with notches and indentations formed by past impacts. The floor has a few low rises in the northern half.
