It is centered at 31.3° north latitude and 121.2° west longitude. It is {{convert|913|km|mi}} long and was named after a classical albedo feature name.<ref>{{gpn|1358}}</ref>
The term "[[Fossa (geology)|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>
