Montes Carpatus is a mountain range that forms the southern edge of the Mare Imbrium on the Moon.

Most of this range consists of a series of peaks and rises, separated by valleys that have been penetrated by lava flows.

The surface to the north of the range is nearly level lunar mare, broken only by the occasional wrinkle ridge or minor impact crater.

Montes Carpatus contains a variety of volcanic landforms: lava flows, pyroclastic deposits, rilles, and others.

Lavas are formed as the mantle begins to melt, so by sampling volcanic rocks of various ages from regions across the Moon, scientists can reconstruct the range of compositions and processes over time.
