BRIEF DESCRIPTION
The eastern part of Mare Serenitatis is intersected in many places by wrinkle ridges, the largest of which approximately follows the line of the meridian 25-degrees E and has a serpentine shape (formerly called Serpentine Ridge). The edge of Mare Serenitatis has a dark border and a series of shallow rilles. The summit of Posidonius Gamma (old name) has a crater pit 2 km in diameter. Refer to your Antonin Rukl Lunar Atlas chart, page 75.
