HiPOD 19 Apr 2023: Possible Chlorides in Terra Sirenum
Most suspected chloride deposits in the Eridania Basin are high-albedo (reflectivity) and found in flattish areas. Around the eastern basin rim, some of these chlorides are distinctively low-albedo, and found in channels. High resolution imagery here may be able to resolve some channel stratigraphy.

HiPOD 18 Apr 2023: A Ridge in Claritas Fossae
An interesting ridge in Claritas Fossae that seems to be superposed over an older series of fractures. This would suggests that the ridge has to be younger and hence emplaced after the tectonic evolution of the area. This might be a surface expression of younger volcanic activity. An alternative explanation would be that this is an erosive remnant or a dike.

HiPOD 17 Apr 2023: Unusual Crater Fill
A public target from HiWish: A possible ancient volcanic formation located near the Thaumasia Plateau with a summit caldera sitting on top of an elevated terrain of hummocky friable materials. Within the crater, an infill unit is horizontally mantling isolated knobs and the crater floor.

HiPOD 14 Apr 2023: A Strangely-Shaped Crater
This small crater appears to be unusual in shape: its rim does not look especially round. This irregular shape may imply an unusual formation mechanism, such as subsequent impact, or some unknown geological process after its initial development.

HiPOD 13 Apr 2023: Ridges along an Escarpment
This observation targets an escarpment (steep slope) along a graben (depression) in the Terra Sabaea highlands. The light-toned graben floor bedrock appears to be composed of a layered material. This observation seeks to characterize the shape of the sinuous ridges at the meter-scale, as well as develop geologic context for their formation.

HiPOD 12 Apr 2023: Channels Intersecting a Crater in Xanthe Terra
This area contains segments of normal faulting and scarp boundary, both related to two phases of crustal collapse with perhaps two different mechanisms. Chaotic collapse of ambiguous (volcanic?) origin might be comparable with the formation of ancient caldera complexes at Arabia Terra. Scientists have long suspected that the valleys of Xanthe Tera were formed by water erosion.

HiPOD 11 Apr 2023: At the Boundary of Chasmata
In geology, “superposition” is used by scientists use to determine the relative ages of rock strata, or layers. The oldest rock strata will be on the bottom and the youngest at the top. With this image, we want to investigate the superposition relationship between the layered rocks and wall rock spurs along the boundary between Ophir and Candor Chasmata.
