Caption:

This Voyager 1 view of an equatorial region near longitude 300 degrees shows several large surface flows that originate in volcanic craters or calderas. At the right edge is a light flow about 250 kilometers long. Another dark, lobate flow with bright edges is just left of center, with an exceedingly dark caldera to its left.
