It is located south of the planet's equator in the heavily cratered highlands of Terra Sirenum in the Phaethontis quadrangle at 48.8°S and 191.2°E.

On the basis of their form, aspects, positions, and location amongst and apparent interaction with features thought to be rich in water ice, many researchers believed that the processes carving the gullies involve liquid water.

Before-and-after images demonstrated the timing of this activity coincided with seasonal carbon-dioxide frost and temperatures that would not have allowed for liquid water.

They have even blown the dust off of the solar panels of the two Rovers on Mars, thereby greatly extending their lives.

Opportunity Rover has lasted over 10 years and is still sending back data as of August 2017.
