Map of Clementine altimetry centered on the Orientale Basin (19°S,
95°W). The basin displays several concentric rings, ranging from
480 kilometers to more than 1000 kilometers in diameter. The topographic
relief of the basin is highly variable. The basin is more than 9 kilometers
deep on the western side but only 3 kilometers deep on the eastern side
of the basin. The red, circular feature below the Orientale Basin is
the Mendel-Rydberg Basin, 500 kilometers in diameter. The huge South
Pole-Aitken Basin is visible on the limb of the Moon at lower left.
