Small Crater within Pollack Crater Containing Light-Toned Material
ESP_018212_1715  Science Theme: Geologic Contacts/Stratigraphy
This observation shows a small crater in within the much larger Pollack Crater containing light-toned material. Pollack Crater is a 90-kilometer diameter impact crater first imaged by the Mariner 9 spacecraft.

This material was first observed by the THEMIS team, and there are multiple Context Camera and Mars Orbiter Camera images showing that this light-toned material may be similar to the large “White Rock” outcrop to the northwest. HiRISE has also imaged White Rock several times. In these cases, we can see how different teams can work together to get an interesting image at high resolution for further study.
