Unknown
This is a small portion of the western edge of the Moon as we see it from Earth. Moon phase revealed features that I have not seen or I have not considered before.
We note here craters like Darwin (130 km), Crüger flooded crater (46 km) of which has remained only its lip on the surface, Byrgius (87 km), Henry (41 km), Henry Freres (42 km), Cavendish (56 km) and Mersenius (84 km).
We also see in the images some deep grooves called Rimae Darwin and Rimae Sirsalis, named after nearby craters or craters which they cross.
In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
