Moa Valles is a well‐preserved, likely Amazonian (younger than 2 Ga old), paleodrainage system that is nearly 300 km long and carved into ancient highland terrains west of Idaeus Fossae. The fluvial system apparently originated from fluidized ejecta blankets, and it consists of a series of dam breach paleolakes with associated fan‐shaped sedimentary deposits. The paleolakes are interconnected and drain eastward into Liberta crater, forming a complex and multilobate deltaic deposit exhibiting a… 
Episodic and Declining Fluvial Processes in Southwest Melas Chasma, Valles Marineris, Mars
There is abundant evidence for aqueous processes on Noachian terrains across Mars; however, key questions remain about whether these processes continued into the Hesperian as the martian climate
Amazonian-aged fluvial system and associated ice-related features in Terra Cimmeria, Mars
Geology of Aeolis Dorsa alluvial sedimentary basin, Mars
ABSTRACT Aeolis Dorsa is a topographic depression, ∼800 km east of Gale Crater, located along the Mars’ dichotomy boundary. This area hosts a set of fluvial sedimentary rocks displaying an
Episodes of Aqueous Flooding and Effusive Volcanism Associated With Hrad Vallis, Mars
Hrad Vallis is an Amazonian‐age outflow channel located in the northwestern part of the Elysium Volcanic Province of Mars. The formation of Hrad Vallis may have been associated with catastrophic
Stratigraphic Relationships in Jezero Crater, Mars: Constraints on the Timing of Fluvial‐Lacustrine Activity From Orbital Observations
On February 18, 2021 NASA's Perseverance rover landed in Jezero crater, located at the northwestern edge of the Isidis basin on Mars. The uppermost surface of the present‐day crater floor is
Fluvial Regimes, Morphometry, and Age of Jezero Crater Paleolake Inlet Valleys and Their Exobiological Significance for the 2020 Rover Mission Landing Site.
A quantitative geomorphological study of the inlet valleys of the Jezero paleolake indicates evidence of a Hesperian age with significant implications for exobiology.
A cold‐wet middle‐latitude environment on Mars during the Hesperian‐Amazonian transition: Evidence from northern Arabia valleys and paleolakes
The growing inventory of post‐Noachian fluvial valleys may represent a late, widespread episode of aqueous activity on Mars, contrary to the paradigm that fluvial activity largely ceased around the
Evidence for Multiple Superposed Fluvial Deposits Within Reuyl Crater, Mars
Reuyl is an 85‐km‐diameter crater located east of the Aeolis Dorsa region. We present results from geomorphic mapping and high‐resolution image analyses of Reuyl to understand the provenance of
Estimated Minimum Life Span of the Jezero Fluvial Delta (Mars).
The results suggest that delta formation occurred over a minimum period of 90-550 years of hydrological activity and implies that the Jezero-lake floor would have been a haven for fine-grained sediment accumulation and hosted an active environment of significant astrobiological importance.


Terraces and Gilbert‐type deltas in crater lakes in Ismenius Lacus and Memnonia (Mars)
Paleolacustrine environments have been widely recognized from landform associations on the surface of Mars. In contrast to paleolakes in more open areas, putative crater lakes commonly display
Recent Fluvial, Volcanic, and Tectonic Activity on the Cerberus Plains of Mars
Athabasca and Marte Valles lie on the Cerberus plains, between the young, lava-covered plains of Elysium Planitia and Amazonis Planitia. To test pre-MGS (Mars Global Surveyor) suggestions of
Asynchronous formation of Hesperian and Amazonian‐aged deltas on Mars and implications for climate
Most fluvial and lacustrine landforms on Mars are thought to be old and have formed more than ~3.8 Gyr ago, in the Noachian period. After a major climatic transition, surface liquid water became less
Fluvial sedimentation conditioned by Quaternary climatic change in central Texas
ABSTRACT The Colorado River of Texas drains a relatively low-relief basin of diverse geology and climate. Detailed geomorphic mapping of Colorado River flood plain and paleochannel morphology on the
The Genesis and Recognition of Anastomosed Fluvial Deposits: Data from the St. Mary River Formation, Southwestern Alberta, Canada
ABSTRACT Data from modern fluvial systems show that the term anastomosed is best reserved for suspended-load systems with multiple channels and very low slope that flow in regions where the

Geological evolution of the Tyras Vallis paleolacustrine system, Mars
[1] Using the new High Resolution Stereo Camera (HRSC) data and other Martian data sets, we reconstructed the hydrological history of an unnamed complex crater in the Xanthe Terra region. The crater
