Palisa catena: Small volcano chains in the western part of the central highlands

The morphology of a series of highland volcanoes found on the floor of the crater Palisa is similar to that of mare volcanoes. The superposition of the cones and craters indicate that this volcano complex had a complex, multiphase history of development. A blanket of relatively dark ash, which is between 4 and 13 km wide, is observed surrounding these volcanoes.
