The Cobra’s Head

Vallis Schroteri

Vallis Schroteri
Sketch by Serge Vieillard

Vallis Schröteri is the largest sinuous valley on the Moon. It makes its start at a 6 km diameter crater just north of Herodotus crater and widens to 10 km. This area is sometimes referred to as the Cobra’s head. It then winds 160 km and narrows to 500 m at it’s end. The rille is likely the result of volcanic activity as a lava flow carved its winding path through the landscape.
