{{Short description|Martian geographical feature}} [[File:ESP_024921fan.jpg|300px|thumb|Wall of trough of Amenthes Fossae, as seen by HiRISE under [[HiWish program]].]]

The '''Amenthes Fossae''' are a system of troughs in the [[Amenthes quadrangle]] of [[Mars]] centered at 9.07°N and 102.68°E. They are 850&nbsp;km across and were named after a classical [[albedo]] feature. The classical albedo feature name was based on the [[Egypt]]ian name for a place where souls of the dead go ([[Amenthes]] or Duat). The name Amenthes Fossae was approved in 1976.<ref>{{GPN|227}}</ref>

The term "fossae" is used to indicate large troughs when using geographical terminology related to Mars. Troughs, sometimes also called [[graben]]s, 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.<ref>[http://www.msss.com/mars_images/moc/2004/01/29/index.html Mars Global Surveyor MOC2-620 Release]</ref>
