Abstract
Some of the subtlest, yet most easily observed features on the Moon are the mare wrinkle ridges, or dorsa. These sinuous ridges, seen in virtually all maria, are the result of the submergence of basin structures, buried crater rims, and compression effects caused by the cooling and shrinking of basaltic mare lavas. They are generally positive relief features; most are between 100- and 300-m high. Despite the low height, the ridges may be hundreds of kilometers long. Wrinkle ridges are best seen close to the terminator when the Sun is near the lunar horizon.
