Bedrock Exposures in Crater Wall
Bedrock Exposures in Crater Wall
ESP_025570_2330  Science Theme: Geologic Contacts/Stratigraphy
This mid-latitude crater appears well-preserved, with a clear ejecta blanket and well-defined rim. Bedrock exposures are visible near the top of the rim. Studying this site can yield information about the underlying terrain within this region.

Additionally, HiRISE images show small-scale features formed through modification and degradation processes; for example, few-meter-wide cracks that run perpendicular to the slope are likely formed through slumping and periglacial processes.

Gullies and flow features are also likely to be found along the crater wall—possible shallow channels starting at the bedrock exposures are visible in along the rim in the upper/left portion of the image.
