An Intense Terminal Epoch of Widespread Fluvial Activity on Early Mars: 2. Increased Runoff and Paleolake Development
TL;DR: In this paper, the authors discuss evidence that highland gradation was prolonged, but generally slow and possibly ephemeral during the Noachian Period, and that the immature valley networks entrenched during a brief terminal epoch of more erosive fluvial activity in the late Noachians to early Hesperians.

An intense terminal epoch of widespread fluvial activity on early Mars: 1. Valley network incision and associated deposits
TL;DR: In this article, the authors present evidence that a final epoch of widespread fluvial erosion and deposition in the cratered highlands during the early to mid-Hesperian was characterized by integration of flow within drainage networks as long as 4000 km and trunk valley incision of 50 to 350 m into earlier Noachian depositional basins.
Journal ArticleDOI
A large paleolake basin at the head of Ma'adim Vallis, Mars.

TL;DR: The size, constant levels, and interior morphology of three regional paleolake basins require a warmer paleoclimate and a long-term, recharged, stable highland water table more than ∼3.5 billion years ago.
Journal ArticleDOI
Interior channels in Martian valley networks: Discharge and runoff production
TL;DR: In this paper, the authors found that channel width and associated formative discharge are comparable to terrestrial valley networks of similar area and relief for 15 narrow channels in basin-filling networks, likely episodic runoff production rates up to centimeters per day and first-order formative discharges of ;300-3000 m 3 /s are similar to terrestrial floods supplied by precipitation.
