Spur is located on the north slope of Mons Hadley Delta, about 200 m above the plain to the north. It is east of the much larger St. George crater, and about 5 km south of the Apollo 15 landing site itself.
The astronauts found the "Genesis Rock", sample 15415, at Spur. The sample contains a large clast of anorthosite, and Dave Scott said "Guess what we just found! I think we found what we came for" as he examined the sample.[2] They also found samples 15445 and 15455, so-called black and white breccias, which are thought to be impact melt breccia resulting from the Imbrium basin impact event.[3]
The crater was named by the astronauts, and the name was formally adopted by the IAU in 1973.[1]
