Abulfeda 13.8°S, 13.9°E

Abulfeda is a very regularly formed crater with a diameter of 65 km and a depth of 3.1 km. The crater floor is relatively smooth and flat, and the southern, inner crater wall exhibits features like landslides. Fairly central there is a craterlet that is surrounded by a very bright halo of ejecta. Large telescopes show additional crater pits and hills on the crater's floor. Abulfeda is a typical crater, like many of the others that were formed during the Nectarian period (between 3.92 and 3.85 billion years ago).

Abenezra 21.0°S, 11.9°E

An almost rectangular crater with a diameter of 43 km and a wall height of about 3.7 km, measured from the crater's floor. The crater Abenezra C (44 km) to the west and partly overlapped by Abenezra, forms part of a trio of craters with Azophi.

Azophi 22.1°S, 12.7°E

A crater 48 km in diameter and 3.7 km deep.

Descartes 11.5°S, 15.7°E

The region around the crater Descartes is very interesting and was therefore chosen as the landing site for Apollo 16. Geologists expected soil samples to be of volcanic origin. Contrary to the lunar geologists' assumptions no rocks of any form of volcanic origin were found in the region.

Descartes is a heavily eroded crater, 48 km in diameter, and exhibits a bright area, extending out from the northern crater wall. The material consists of breccia and once molten highland material. The origin of the bright ejecta is uncertain. The crater wall of Descartes A (16 km) also appears extremely bright in sunlight. In 1999, the lunar probe Lunar Prospector flew over this area at a low altitude and registered strong magnetic anomalies beneath the lunar surface (a magcon). The Descartes region obviously still holds many unsolved riddles.
