The Glorious Serpentine Ridge

One of the most wondrous lunar sights can be observed when the Moon is 6 days old. Paralleling the eastern shore of Mare Serenitatis is the snakelike Serpentine Ridge. This fine name has been around since Schroeter (1790s), but the IAU, in their woeful ignorance of history and selenology, gave different parts of this obvious single structure two unnecessary names: Dorsum Smirnov and Dorsum Lister. Bruno Daversin's exquisite image reveals both the broad and detailed structure of this wrinkle ridge system. Mare ridges generally have a a wide swelling with one edge being steeper-sided and higher. This can be well seen near the crater Very (large crater near the upper left). From Chuck Wood
This is a classic LPOD from Nov 11, 2004. I'll be happy when more current images are available!
