Geological Chronicle
J. Herschel is a large lunar impact crater of the variety termed a walled plain, located in the northern part of the Moon's surface where it appears foreshortened when viewed from Earth. Named after British astronomer John Herschel, its southeastern rim forms part of the edge of Mare Frigoris, with the crater Anaximander situated to the northwest.
The crater's rim has been heavily eroded, frequently described as considerably disintegrated. The remaining rim survives as a ring of ridges resculpted by subsequent impacts, bordered along its northern rim by a large, unnamed lunar plain.
The interior floor is relatively level but irregular, marked by a multitude of tiny impacts that include satellite craters C, D, K, and L. Attached to the southern rim is Horrebow A, which is overlapped along its southwest rim by the small crater Horrebow.
