Clockwise from upper left is a Voyager 1 high resolution image, a Galileo enhanced color image, a Galileo image with simulated Voyager colors, and a Voyager 2 color image.
North is to the top of the picture.
The Galileo images show new diffuse deposits which have an unusual morphology for plume deposits. A diffuse yellowish deposit with a radius of 285 km extends to the northwest, whereas an intense reddish deposit marks a curving fallout margin to the southeast. This morphology may have resulted from the presence of a topographic obstruction to southeast of the vent.
