Geologic map of the Eudoxus Quadrangle of the Moon

The Eudoxus quadrangle is in the northeastern part of the Moon’s nearside hemisphere. It is bordered on the west by Montes Caucasus, which form part of the main rim of the multi-ring Imbrium basin (Hartmann and Kuiper, 1962), and on the south side by Mare Serenitatis, which occupies another large multi-ringed basin. South and east of the prominent crater Eudoxus elevations decrease and the rugged highland terrain becomes more subdued and covered by mare materials in the Serenitatis basin, Lacus Somniorum, and Lacus Mortis.
