Lacus Mortis

Lacus Mortis
Diameter 151 km
Eponym Lake of Death

Lacus Mortis, latin for "Lake of Death", is a plain of basaltic lava flows in the northeastern part of the Moon. It lies just to the south of the elongated Mare Frigoris, being separated by a slender arm of rugged ground. To the south is the Lacus Somniorum, separated from this mare by the joined craters Plana and Mason, and a strip of uneven surface.

Located prominently just to the east of the mid-point of this feature is the crater Bürg. The western part of the Lacus Mortis contains an extensive system of criss-crossing rilles collectively designated Rimae Bürg.

The selenographic coordinates of the Lacus Mortis are 45.0° N, 27.2° E, and it has a diameter of 151 km.
