While there was not much by way of science rationale for this observation, Terra Sirenum is a large area of Mars in the Southern Hemisphere and is believed to have once held a lake that eventually drained through Ma’adim Vallis. The THEMIS instrument on the Mars Odyssey orbiter has detected evidence of chloride-based minerals dated well over 3.5 billion years. This image shows some lighter-toned bedrock that may represent these minerals.

NaCl? Was it a salt lake? Ariadnes Colles, Gorgonum and Atlantis Chaos are a very interesting area of Mars, home to the ancient lake of Eridania. 3.5 billion years ago it was Hesperian, I thought it was older, than Noachian
