[1] We present evidence that a final epoch of widespread fluvial erosion and deposition in the cratered highlands during the latest Noachian or 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. Locally deltaic sediments were deposited where incised valley systems debouched into basins. Large alluvial fans of sediment deposited from erosion of alcoves in… 

An Intense Terminal Epoch of Widespread Fluvial Activity on Early Mars: 2. Increased Runoff and Paleolake Development

[1] To explain the much higher denudation rates and valley network development on early Mars (>∼3.6 Gyr ago), most investigators have invoked either steady state warm/wet (Earthlike) or cold/dry

A Diverse Array of Fluvial Depositional Systems in Arabia Terra: Evidence for mid‐Noachian to Early Hesperian Rivers on Mars

The morphology of these depositional systems is supportive of an early Mars climate, which was characterized by prolonged precipitation and runoff, and regional stratigraphic relations suggest these systems were active between the mid‐Noachian and early Hesperian.

Characterizing Water on Early Mars through the Geomorphic Analysis, Crater-Age Dating, and Sediment Transport Modeling of Valley Networks and Deltas

The presence of valley networks across much of the ancient surface of Mars, together with the locations and morphologies of the ancient Martian deltas and paleolakes, provides strong evidence that

Evidence for a short period of hydrologic activity in Newton crater, Mars, near the Hesperian‐Amazonian transition

Hesperian/Amazonian‐aged valleys and alluvial fans distributed in regional clusters throughout the southern middle‐ to low‐latitudes were formed during a period of fluvial runoff and erosion which

Fluvial stratigraphy of valley fills at Aeolis Dorsa, Mars: Evidence for base-level fluctuations controlled by a downstream water body

Aeolis Dorsa, a large sedimentary basin on Mars, contains an array of fluvially dominated sedimentary deposits. These deposits preserve a record of fluvial erosion and deposition during early Martian

The global distribution of depositional rivers on early Mars

Sedimentary basins are the archives of ancient environmental conditions on planetary surfaces, and on Mars they may contain the best record of surface water and habitable conditions. While

Valley formation on early Mars by subglacial and fluvial erosion

The southern highlands of Mars are dissected by hundreds of valley networks, which are evidence that water once sculpted the surface. Characterizing the mechanisms of valley incision may constrain
