Rima Hyginus

In the upper left of the image is the crater Hyginus, a small lunar crater located at the east end of Sinus Medii. The crater rim is split by a long linear rille that branches to the northwest and to the east-southeast for a total length of 220 kilometers. The crater is deeper than the rille, and lies at the bend where they intersect. Together the Hyginus crater and Rima Hyginus form a distinctive and prominent feature in an otherwise flat surface. Smaller craterlets can also be discerned along the length of this rille, possibly caused by a collapse of an underlying structure.
