Moon: North Region

The Northern Region’s most prominent feature is Mare Imbrium, one of the largest impact basins in the solar system. The flooded basin is flanked to the east by a partial ring of mountains - some reaching of 5 km in height - the “Alps”, the “Caucasus” and the “Apennines”. The mountains to the North East are divided by the broad “Alpine Valley” and to the North by the dark basalt-flooded crater Plato. A collection of interesting craters, isolated mountains and rilles pepper Mare Imbrium’s dark surface.
