Montes Archimedes coordinates of this range is 25.3° N, 4.6° W. The peaks of Montes Archimedes occupy an area with a maximum diameter of 163 km, although the most rugged portion of the terrain is concentrated within the central 70 km. The remainder of the peaks are scattered across the plateau, with no particular structure or pattern. Some of the peaks in this range achieve heights of up to 2.0 km, much less than those in the Montes Apenninus, for example, and none have received specific designations.
