Textured Crater Floor in the Arabia Region

Textured Crater Floor in the Arabia Region
ESP_024870_2080  Science Theme: Geologic Contacts/Stratigraphy
Surrounding the uplifted bedrock in the center of this large crater is mottled terrain. What possibly caused this?

The floor of the crater might be the result of icy flows. Perhaps an ancient aquifer system was exposed at the time of the impact resulting in the incredible mottled floor we see now, which appears different from the uplifted central peak.

This caption is based on the original science rationale.
