It is 280&nbsp;km long and was named after an albedo feature at 44S, 130W.<ref>{{cite web |url=http://planetarynames.wr.usgs.gov |title=Gazetteer of Planetary Nomenclature |website=[[Astrogeology Research Program]] |publisher=[[United States Geological Survey]] |access-date=20 March 2022}}</ref>

Fossae are large troughs (long narrow depressions) in the geographical language used for Mars. This term is derived from Latin; therefore fossa is singular and fossae is plural.<ref>[http://www.marsartgallery.com/marsnames.html Mars Art Gallery Martian Feature Name Nomenclature<!-- Bot generated title -->]</ref> Troughs form when the crust is stretched until it breaks. The stretching can be due to the large weight of a nearby volcano. Studies have shown that the volcanoes of Tharsis caused most of the major fossae on Mars. The stress that caused the fossae and other tectonic features is centered in [[Noctis Labyrinthus]], at 4 S and 253 E. But the center has moved somewhat over time.<ref name="Carr2006">{{cite book|author=Michael H.
