Surface features As mentioned above, small patches of pure water ice with an albedo as high as 80% are found on the surface of Callisto, surrounded by much darker material. [4] High-resolution Galileo images showed the bright patches to be predominately located on elevated surface features: crater rims , scarps , ridges and knobs. [4] They are likely to be thin water frost deposits . Dark material usually lies in the lowlands surrounding and mantling bright features and appears to be smooth. It often forms patches up to 5 km across within the crater floors and in the intercrater depressions. [4] Two landslides 3–3.5 km long are visible on the right sides of the floors of the two large craters on the right. On a sub-kilometer scale the surface of Callisto is more degraded than the surfaces of other icy Galilean moons . [4] Typically there is a deficit of small impact craters with diameters less than 1 km as compared with, for instance, the dark plains on Ganymede . [13]
