The Humorum, MARE (Sea of humidity) is southern next to the Procellarum, Ocean. The sea of humidity has a round shape with a diameter of about 400km, and a huge crater of Gassendi is positioned at the northern coast of the lunar sea. The crater has several central peaks inside, which can be observed with amateur telescopes under good conditioned aerial current.
We can detect wrinkle like features in the outskirts of almost all round lunar seas. Of course the Humorum, MARE is not an exception. It's considered that the features have been completed by crookedness of tension caused from sinking thick basaltic stratum.
Another scenic spot in this picture, the crater of Schickard is lying near the western edge of the Moon with a diameter of about 227km. Most of the crater was under shadow yet when this picture was taken, but you can barely see the outer rim of crater.
