English: Oblique view of part of part of Pytheas, on the moon. This is Figure 146 of Apollo Over the Moon (NASA SP-362, 1978), which has the following caption:
The Apollo 17 panoramic camera provided this high-resolution, enlarged view of the south wall of Pytheas. Pytheas is about the same size as Bessel (fig. 145), but is located in south-central Mare Imbrium almost 1100 km west of the latter. The outcrops in the walls of the two craters are remarkably similar. These and the many other craters in mare areas that contain outcrops of dark horizontally layered rock demonstrate the moonwide uniformity of conditions in the upper part of the mare basins.-M.C.M.
