- AS11-42-6214 and AS11-42-6222 (made during the mission of Apollo 11 in july 1969) show orbital northwest-looking views of both Firmicus (foreground) and Mare Crisium in the distance. Note the dark streak of Lacus Perseverantiae nearby Firmicus.
- Apollonius N, the 9th item in C.A.Wood's list of Concentric Craters (1978), is noticeable on the Hi-Res scan of Lunar Orbiter 4's photograph LOIV-184-h1. Because of the oblique look at it (at the region of Apollonius and Apollonius N) it's rather difficult to locate both of them. But... once you have detected the dark-floored FIRMICUS, it will be an easy task to discover Apollonius N. In this online scan of LOIV-184-h1, we are looking "upside down" at the Apollonius region (north toward the bottom). The Concentric Crater Apollonius N is "just above" the dark-floored Firmicus (in reality it's SOUTH of Firmicus).

Some distance on the E., Madler noted a number of dark-grey streaks which apparently undergo periodical changes, suggestive of something akin to vegetation. They are situated near a prominent mountain situated in a level region.
