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

Inverted terrain shows ancient stream-flow details
River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the … Continue reading

HiRISE: Transition from depressed to inverted channels in Gorgonum Basin
This image shows a transition from depressed to inverted channels in the Gorgonum Basin. In the darker terrain, there are two channels that display depressed topography. As these two channels cross into the underlying brighter terrain, the channels now stand … Continue reading

HiRISE: An inverted crater
There is a circular feature in this observation that appears to stand above the surrounding terrain. This feature is probably an inverted crater: a once-normal appearing impact crater that was filled in with sediment. The fill became indurated, or hardened, … Continue reading

HiRISE: Inverted terrain in Eridania Basin
The Eridania Basin is thought to have once contained a large sea. This image shows the Gorgonum Basin, which lies along the eastern edge of Eridania. Along this eastern boundary, the terrain is being eroded away to expose light-toned altered … Continue reading
