Schroeter's Valley

Schroeter's valley can clearly be seen emerging between two prominent 25-mile craters, Herodotus and the brighter Aristarchus. The craters are apparently of very different age. Herodotus is was flooded with lava when the surrounding mare was formed and therefore predates it and has a darker, smooth lava-filled floor. The much brighter Aristarchus crater resulted from a meteor impact later.

Schroeter's valley emerges behind the peak between the craters (on Apollo images taken from the other direction it looks like the valley was formed by fast-flowing lava emerging from an underground tunnel) and winds its way round towards the West for about 100 miles and then disappears as it becomes narrower.

Here are further images taken over the last few years:

The two small bright craters alongside the valley before the bend are Aristarchus Z and - further from the valley - crater Vaisala, just 5 miles wide. In the background, the rising sun is touching the peaks of the Agricola mountains. Towards the East of the valley (bottom right centre of the image) are the Harbinger mountains with the half-crescent remains of crater Prinz (30 miles). Just North lies crater Krieger which has 6-mile crater Van Biesbroeck in its southern rim. Moving through Mare Imbrium further East, craters Diophantus (12 miles) and Delisle (17 miles) are clearly seen in the centre of the image.

Here is another, later image:
