At Voyager resolution, dark terrain on Ganymede (about 50 percent of the surface) is seen to be made up of furrows, craters, palimpsests, and dark plains material. Based on Voyager data, a variety of origins have been proposed for the formation and evolution of dark terrain and the source of the darkening agent. New data from Galileo have shown that the dark material in Galileo Regio is very heterogeneous when seen at high resolution. Highest albedo material is present in the form of isolated knobs and massifs, crater rims and walls, furrow rims, and some plains units. Lower albedo material is found in crater and furrow floors, as plains units, as streaks on slopes, and as a hummocky unit interpreted to be crater ejecta. We here present new evidence from the Galileo G1 and G2 orbits (G2 provided stereo coverage over approximately one third of the G1 target area) as to the nature and origin of the dark material and the implications for dark terrain evolution.
