On images of the Mars Reconnaissance Orbiter -MRO- a british research team has discovered possible "spillway" of ancient martian lakes.
The pits in the equatorial region of Ares Vallis were first explained as remains of evaporating water ice, but the discovered channels seems to connect different basins, much more like thermokarst- lakes connected by small rivers. The estimated age of the features is with only 3 billion years surprisingly young.
