monotones plains of Sinus Aestuum are surrounded by interesting
formations. Most interesting being Eratosthenes. South-east of
Eratosthenes the mountains of ghost crater Stadius and to the north - west
of Stadius we find a chain of craters running north. (See chart

lunar dome. When the light comes in at very low angles we see dark spots
south of crater Copernicus C, and north of Schröder. Not far from Gambart
C we find the landing spot of
Bay of Billows. Named by:
