26.Cleomedes

The north-western part of Mare Crisium is surrounded by mighty mountain ranges. If the light comes in at a low angle we see many ridges crisscrossing the mare. The rays of Proclus reach till here, and when the Sun is high in the local sky, they become very bright for observers on Earth.

CLEOMEDES - Cleomedes (1th Century BC) (Κλεoμήδης) Greek astronomer who is known chiefly for his book "On the Circular Motions of the Celestial Bodies".

Crater (126km /78Mi ) (Dept: 2,700m /8,858ft) (27.7N, 55.5E) Heavily worn and eroded, especially along the southern part of the wall.

PROMONTORIUM LAVINIUM - PROMONTORIUM OLIVIUM - Two Capes pointing towards each other, at the western edge of Mare Crisum. (Named by William Birt) Inbetween the two capes, not a Bridge, as was suggested in the past, by amateurs John J O'Neill and  H.P.Wilkins, but two craters. 

Capes. (6km /4Mi ) (14.9N, 49.5E) (In)Famous capes. In the 1950s a bridge was spotted in-between the two capes...(Since then the Lunar Authorities have taken it down). J
