L19: Alpine Valley

This 166 km long valley cuts straight through Montes Alpes, and connects Mare Imbrium to the southwest with Mare Frigoris to the northeast. The valley is believed to be a graben flooded with material from the adjacent mares.

Under excellent conditions a rille can be seen bisecting the valley, but not so during my observation.
