Evidence for fluvial deposition in Arabia Terra
[Editor’s note: From a paper by Joel Davis and six co-authors recently published in the Journal of Geophysical Research.] A Diverse Array of Fluvial Depositional Systems in Arabia Terra: Evidence for mid‐Noachian to Early Hesperian Rivers on Mars • Fluvial … Continue reading

HiRISE: Transition
Transition. This image shows where a fluvial channel changes from a depression to an inverted high standing channel in Terra Sirenum. That change likely marks the spot where the material was possibly elevated and more resistant to erosion. HiRISE Picture … Continue reading
HiRISE: Positive relief features in Xanthe Terra
Positive relief features in Xanthe Terra. These relief features, which are positively gorgeous, might be inverted streams. Xanthe Terra is a large area on Mars, centered just north of the Martian equator. HiRISE Picture of the Day archive [More at … Continue reading

HiRISE: Fan with inverted channels
This image shows inverted channels within a fan whose origin could be either fluvial (produced by the action of a stream) or alluvial (created by sedimentary deposits). If the fan is alluvial, then it formed on dry land. If the … Continue reading

HiRISE: Semi-sinuous ridge and stratified material in Arabia Terra
Semi-sinuous ridge and stratified material in Arabia Terra. Looks like inverted stream channels that contributed to a lake or pond, with stratified sedimentary rock units in the depression. Important imaging for understanding how to best distinguish cratered, erosion-resistant sedimentary rock … Continue reading

HiRISE: Inverted channels
Inverted channels at the boundary of highlands and intercrater plains. This image targets inverted channels located at the boundary between Noachian highlands and Noachian intercrater plains bedrock. These channels are 200 to 500 meters wide, implying substantial fluvial activity. High-resolution … Continue reading

HiRISE: Big fans
Alluvial fans are fan-shaped deposits emerging from regions of steep topography. Alluvial fans on Mars are thought to be ancient and record past episodes of flowing water. This image shows part of one of those fans, which has been eroded. … Continue reading

HiRISE: Inverted channel in Eberswalde Crater
An inverted channel in Eberswalde Crater. Eberswalde Crater was once a final candidate landing site for the Mars Science Laboratory rover, Curiosity. Although the primary scientific interest in Eberswalde is its well-preserved delta, this sinuous river channel to the southeast, … Continue reading
