Small Floral-Shaped Volcano on Cerberus Fossae
Small Floral-Shaped Volcano on Cerberus Fossae
ESP_024378_1880  Science Theme: Volcanic Processes
This is a small volcano superposed on the flanks of a larger one of the Cerberus Tholi.

This smaller feature has a single vent, aligned along a Cerberus Fossae trough, and it has flows radiating away from this vent in all directions, somewhat looking like a flower.

These flows appear somewhat darker than their surroundings, though this might be owing to roughness as much as to relative youth. Note that even at Context Camera (CTX) scale, we can see that there are some small impact craters superimposed on this feature, indicating that it is not entirely young.

This caption is based on the original science rationale.
