Slipher is the crater at bottom left, with impact melts north of it. The much larger crater northeast of Slipher is d'Alembert.
The small crater on the southwestern part of Slipher's rim is Slipher S.
Slipher's location is very near the southwestern part of d'Alembert's rim, and it's as if Slipher is always trying to escape out of d'Alembert, pulling part of d'Alembert with it. The same thing seems to happen within Slipher (with Slipher S).

Description
Slipher's location is at the southwestern part of the much larger crater d'Alembert.
As mentioned above, it's as if Slipher is always trying to escape, pulling part of d'Alembert's rim with it, southwest-ward.
The same thing seems to happen within Slipher itself. Small crater Slipher S is also trying to escape, pulling part of Slipher's rim with it.

Nomenclature
- Earl Charles Slipher (March 25, 1883 – August 7, 1964) was an American astronomer. He was the brother of astronomer Vesto Slipher. Slipher was born in Mulberry, Indiana. He joined Lowell Observatory in 1908 and became a noted planetary astronomer, concentrating on Mars. He published Photographic History of Mars (1905-1961).
- Vesto Melvin Slipher (November 11, 1875 – November 8, 1969) was an American astronomer. He spent his entire career at Lowell Observatory in Flagstaff, Arizona, where he was director from 1916 to 1952. He used spectroscopy to investigate the rotation periods of planets, the composition of planetary atmospheres. In 1912, he was the first to observe the shift of spectral lines of galaxies, so he was the discoverer of galactic redshifts. He was responsible for hiring Clyde Tombaugh and supervised the work that led to the discovery of Pluto.
