- Although the LPI's search list for orbital Apollo photographs shows nothing for Saunder, this crater WAS captured on several north-looking frames made by Apollo 16's mapping/metric Fairchild camera. One of those frames is AS16-M-0836, which shows Saunder a little bit above and to the right of the frame's centre.

Ruins of a very ancient large crater southeast of Saunder
- Southeast of Saunder there seems to be a circle-shaped arrangement of elevations that looks more-or-less like the ruins of a large crater the size of Hipparchus. This circle-shaped tendency is depicted on SLC map C5 (System of Lunar Craters, 1966). How much of this ancient crater could be observed during low-sun circumstances? - DannyCaes Jan 21, 2017
- Named for Samuel Arthur Saunder (1852-1912), a British mathematician and selenographer. In the early 1900's Saunder initiated a program to measure precise positions of lunar craters to extend the accuracy of hand drawn lunar maps. His control points served as the basis for the positions reported in the IAU's Named Lunar Formations. Saunder's Presidential Address to the 1903-4 Session of the BAA includes an interesting history of lunar cartography and its usefulness, or lack of usefulness, for detecting changes on the Moon.
- Named by Karl Müller in Named Lunar Formations in 1935 (Whitaker, p 229).
