New evidence has been found suggesting that water could have flowed on Mars as recently as 1.25 million years ago. Planetary geologists at Brown University discovered a gully fan system on the surface that appears to have been formed by melt water from snow and ice deposits.
Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago. The fan offers compelling evidence that it was formed by melt water that originated in nearby snow and ice deposits and may stand as the most recent period when water flowed on the planet."
