Mars Water Flow Reconstructed

A barren landscape shaped by water

 

The Holden Basin* is part of a series of channels and sinks called the Uzboi-Ladon-Morava (ULM) outflow system that may have once drained up to 9% of the martian surface. The complex history of the ULM outflow system makes it an interesting target to explore in more detail with Mars orbiters and rovers.

 

In the maps on the right and directly below, we see the Holden Basin and the full ULM outflow system in context. The solid royal blue colour in the map below shows how water once flowed across this region of Mars; it would have started in channels that drain into the Argyre Planitia, then flowed through Uzboi Vallis into the location now scarred by the Holden Crater. From there it would have collected in the Holden Basin before streaming through Ladon Valles to Ladon Basin and beyond.
