Hephaestus Fossae [SEP] located on astronomical body
Hephaestus Fossae
The Hephaestus Fossae are a system of troughs and channels in the Amenthes quadrangle of Mars, with a location centered at 21.1 N and 237.5 W. They are 604 km long and were named after a classical albedo feature name. The fossae have been tentatively identified as outflow channels, but their origin and evolution remain ambiguous. It has been proposed that water may have been released into the troughs as a catastrophic flood due to subsurface ice melting following a large bolide impact.

Fossa (planetary nomenclature)
In planetary nomenclature, a fossa (pl. "fossae") is a long, narrow depression (trough) on the surface of an extraterrestrial body, such as a planet or moon. The term, which means "ditch" or "trench" in Latin, is not a geological term as such but a descriptor term used by the United States Geological Survey (USGS) and the International Astronomical Union (IAU) for topographic features whose geology or geomorphology is uncertain due to lack of
