| Naming | a classical albedo feature name |
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.[1] The fossae have been tentatively identified as outflow channels, but their origin and evolution remain ambiguous.[2] 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.[3]
