eponym=Edward S. Holden Holden is a 140km wide crater on
Mars , located with the southern highlands. It is named afterEdward Singleton Holden , an American astronomer.Like Gusev, it is notable for an outlet channel,
Uzboi Vallis , that runs into it, and for many features that seem to have been created by flowing water.The crater's rim is cut with gullies, and at the end of some gullies are fan-shaped deposits of material transported by water. Holden is an old crater, containing numerous smaller craters, many of which are filled with sediment. The crater's central mountain is also obscured by sediment.
