Schroter's Valley, frequently known by the
Latinized name Vallis Schröteri, is a sinuous valley or rille on the surface of the
near side of the Moon. It is located on a rise of continental ground, sometimes called the
Aristarchus plateau, that is surrounded by the
Oceanus Procellarum to the south and west and the
Mare Imbrium to the northwest. At the southern edge of this rise are the craters Aristarchus and
Herodotus.
This is the largest
sinuous rille on the Moon. It begins at a 6 km diameter crater located 25 km to the north of Herodotus. (The start of the rille has been termed the "Cobra's Head" by some observers, due to its resemblance to a snake.) From the crater it follows a meandering path, first to the north, then setting a course toward the northeast, before finally bending back to the south until it reaches a 1 km high precipice at the edge of the Oceanus Procellarum. The rille has a maximum width of about 10 km, then gradually narrows to less than a kilometer near its terminus.
The origins of this rille are believed to be volcanic. The interior floor has been resurfaced and is very level. However there is a slender rille located on the floor, which can be photographed from Earth with a good telescope and good seeing.
The rille has been the subject of numerous
transient lunar phenomena observations.
The selenographic coordinates of this valley are 26.2°N 50.8°W, and it has a maximum diameter of 168 km. It is named for Johannes H.
Schröter.
It was a potential landing site for the canceled Apollo 18 mission
