Today's Image of Mars shows a small floral-shaped volcano in Cerberus Fossae.You can see the flows because they are darker than the surrounding terrain and radiate away from the opening, forming a flower shape. The volcano lies at the flank of a larger one of the Cerberus Tholi.
To the right you can see this volcanoes only vent. You will also notice that there are a few small crater superimposed over the lava flows, which indicates that this feature is "not entirely young." (HiRISE)
Cerberus Fossae is a series of roughly parallel fissures created by faults which pulled the Martian crust apart in the Cerberus region, which is located at around 9°N, 197°W. These faults are the result of the formation of the Elysium Volcanic Field. They pass through preexisting features, like hills, which indicates that the faults are relatively recent.
