Floral-Shaped Volcano on Cerberus Fossae

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 is a stereo pair with ESP_023811_1880.

Note: Cerberus Tholi is a group of seven volcanic hills located in Elysium Planitia. Cerberus Tholi is located south of the eastern end of Cerberus Fossae, and roughly encircle Tombaugh Crater.
