This picture shows Ptolemaeus under a Sun elevation angle of 45°. The undulations on the Cayley Formation are so subtle that they disappear under the high Sun. The arrows point to examples of the small, relatively sharp, young craters with central mounds mentioned in figure 54. The mounds may be harder than the shallower materials and may indicate the depth of the regolith formed on the Cayley. -R.E.E.
