(formerly Archimedes M)

AS15-M-0418 Spurr, a "ruined" crater in the northwestern part of Palus Putredinis, near Archimedes, is marked by a surviving crescent of unflooded crater rim. The ridges in the upper left are not named.
- Spurr was also captured by the panoramic ITEK camera of Apollo 15. AS15-P-9823 shows the arc of the shadowless Spurr beyond (to the right) of the frame's centre.

- From the shadows in AS15-M-0418, the east wall rises to from 130-155 m above the central mare, increasing to about 180 m at one point in the southwest. On the west, the highest point (casting the longest shadow) is about 245 m above the mare. These values appear to be consistent with the 100-m contours (obtained by stereo mapping) on LTO 41A3. - Jim Mosher
- Named for Josiah Edward Spurr (1870-1950), an American geologist who wrote a multi-volume book about the Moon, called Geology Applied to Selenology.
- This replacement name for a formerly lettered crater was introduced on LTO-41A3 (Jan. 1974; for which it served as the chart title). Spurr appears in the cumulative list of approved names in IAU Transactions XVB (1973), and does not appear in any of the previous Transactions, so the name appears to have been approved in that year. Biographical information was unofficially reported in Ashbrook, 1974.- Jim Mosher
- Although the LTO identifies the former name as Archimedes K it in fact appars to have been Archimedes M (as reported in Ashbrook).
- Not to be confused with Spur (craterlet near the site of Apollo 15), or Silver Spur (mountain near the site of Apollo 15).
