Cruls is an impact crater in the Eridania quadrangle on Mars at 42.91° S and 163.03° E. and is 87.89 km in diameter. Its name was assigned in 1973 by the International Astronomical Union, in honor of Brazilian astronomer Luis Cruls.[1] Evidence of previous glacial activity is evident in images.[3]
Nearby prominent craters include Corozal almost to the northwest, the recently named Nqutu and Tarq to the northeast, Bjerknes to the east, Rossby to the southeast and Huggins to the west. At the vicinity of Rossby towards the southeast is the valley known as Drava Valles.
Glacial Features
Glaciers, loosely defined as patches of currently or recently flowing ice, are thought to be present across large but restricted areas of the modern Martian surface, and are inferred to have been more widely distributed at times in the past.[4][5]
