Uzboi-Landon-Morava
The Uzboi-Landon-Morava (ULM) outflow system is a long series of channels and depressions that may have carried water across a major part of Mars. It starts with channels that drain into the Argyre basin in the Argyre quadrangle. Water ponded in the Argyre basin, then the overflow is believed to have traveled northward through Uzboi Vallis, into Landon basin, through Morava Valles, to the floor of Margaritfier basin. Some of the water may have helped to carve Ares Vallis. Altogether
than Earth's Lake Huron. This happened when water burst through a crater rim that was damming it. Holden is an old crater, containing numerous smaller craters, many of which are filled with sediment. Indeed, over 150 m of sediment is exposed in Holden Crater, especially in southwestern part of the crater. The crater's central mountain is also obscured by sediment. Much of the sediment probably originated from river and lake deposits. Holden Crater is in the Uzboi-Landon-Morava (ULM) outflow system.
