HiRISE: Narrow troughs
Narrow troughs. What exactly are the nature of these thin, narrow troughs? They might may be part of a system of dikes that came from the same magma source that fed the whole area in Thaumasia Planum, just south of … Continue reading

HiRISE: Terraced trough near Ceraunius Fossae
A terraced trough near Ceraunius Fossae. This may be a source region of flow material that enclosed the adjacent raised ridges and continues on to the north. High resolution can help to determine if the terraced forms are due to … Continue reading

HiRISE: Troughs and ridges
Troughs and ridges. These wide troughs in Chryse Planitia have a narrow ridge running down the middle. How did these form? (North is to the right.) HiRISE Picture of the Day archive. [More at links]

HiRISE: When lava moved
When lava moved. The objective of this observation is to examine the remains of an ancient lava flow moving in a trough in the Claritas Fossae region. Pictures like this may tell us more about how lava flowed on Mars. … Continue reading

HiRISE: Hephaestus Fossae pits
Hephaestus Fossae pits. The Hephaestus Fossae are a system of troughs and channels that are about 604 kilometers in length. The fossae have been tentatively identified as outflow channels, but their origin and evolution remain ambiguous. HiRISE Picture of the … Continue reading

HiRISE: Blocks and troughs
Blocks and troughs. This region in Margaritifer Chaos is located in a system of finger-like rifts and cracked surface stretching south from what appear to be three impact craters. The interaction/relation between these valleys and their neighboring craters could be … Continue reading

HiRISE: Nilosyrtis Mensae
Let us now contemplate Nilosyrtis Mensae. There is a fault attached to a trough here; both have the same orientation. This image helps us to understand stress fields on Mars. Beautiful Mars series. [More at links]

HiRISE: Troughs with axial ridges in Acidalia Planitia
Troughs with axial ridges in Acidalia Planitia. There are large, hundreds of meters in length, troughs in Acidalia Planitia, with high axial ridges down the center. While they appear fairly bland in Mars Orbital Camera images, we can see better … Continue reading

HiRISE: Troughs in Elysium Fossae
The two linear depressions in this image form part of the Elysium Fossae complex, a group of troughs located in the Elysium quadrangle of Mars. These troughs are tectonic features, likely formed by the stretching, tearing and subsequent collapse of … Continue reading
