TheAmenthes Fossae are a system of troughs in theAmenthes quadrangle ofMars centered at 9.07°N and 102.68°E. They are 850 km across and were named after a classicalalbedo feature. The classical albedo feature name was based on theEgyptian name for a place where souls of the dead go (Amenthes or Duat). The name Amenthes Fossae was approved in 1976.[1]
The term "fossae" is used to indicate large troughs when using geographical terminology related to Mars. Troughs, sometimes also calledgrabens, form when the crust is stretched until it breaks, which forms two breaks with a middle section moving down, leaving steep cliffs along the sides. Sometimes, a line of pits form as materials collapse into a void that forms from the stretching.[2]
