The climate history of early Mars: insights from the Antarctic McMurdo Dry Valleys hydrologic system
JW Head, DR Marchant - Antarctic Science, 2014 - cambridge.org
The early climate of Mars (Noachian Period, the first~ 20% of its history) is thought to differ
significantly from that of its more recent history (Amazonian Period, the last~ 66%) which is …
