Description
Originally an informal name used by geologists to refer to the extensive [/Mare%20Imbrium Imbrium]-facing side of the [/Montes%20Apenninus Apennine Mountains], a small portion of this later visited by Apollo 15 astronauts was labeled Apennine Front on Topophotomap 41B4S1 and on Site Traverse Map 41B4S4 and has become part of the [/IAU%20Nomenclature IAU Nomenclature]. In reading journal articles, it is often difficult to distinguish whether the authors are referring to the specific small area labeled on Topophotomap 41B4S1, to everything along the base of the Apennines near the [/Apollo%2015%20site Apollo 15 landing site], or to the "Apennine Front" in the broadest sense.
This use on the map is at odds with all use in the lunar geologic literature. The Apennine Front is the scarp along the [/Mare%20Imbrium Mare Imbrium] facing side of the [/Montes%20Apenninus Apennines]. - tychocrater tychocrater May 23, 2009

Additional Information
- In the IAU sense, the [/Landing%20Site%20Name Landing Site Name] Apennine Front is a [/Minor%20Feature Minor Feature] for which Topophotomap 41B4S1 is given as the reference. On that map, it marks the point where the slope of [/Mons%20Hadley%20Delta Mons Hadley Delta] meets the plain of [/Putredinis%2C%20Palus Palus Putredinis]. Most of the Apollo 15 "Apennine Front" samples were actually collected in the vicinity of [/Spur Spur], a 90 m diameter impact crater about 300 m from the base (~70 m higher in elevation). Site Traverse Map 41B4S4 places the Apennine Front label much higher up the slope, well above [/Spur Spur] crater, a little over 1 km from the location indicated on Topophotomap 41B4S1.
- The name also appears on a Map of informal astronaut-assigned landing site names posted in Eric Jones' Apollo 15 Image Library, but it does not appear to have been intended to refer to any specific feature.
- As indicated in the title line of this page, the IAU's Apennine Front has been assigned an official "diameter" of 6 km, although no specific boundaries are indicated on any of the maps cited above.
- Because the IAU's [/IAU%20Nomenclature Planetary Gazetteer] lists feature positions only to the nearest 0.1 degrees in lunar longitude and latitude, the officially listed coordinates of Apennine Front and [/Spur Spur] are identical (25.9 N/3.7 E), even though they are presumably distinct features. In the Apollo 15 control system, [/Spur Spur] crater is actually shown at 25.974 N/3.657 E. The center of the Apennine Front label is placed at 25.976 N/3.680 E (foot of [/Mons%20Hadley%20Delta Mons Hadley Delta] slope) on Topophotomap 41B4S1, and at 25.957 N/3.643 E (well up the [/Mons%20Hadley%20Delta Mons Hadley Delta] slope) on Site Traverse Map 41B4S4.
Nomenclature
- Apennine Front is listed in the [/IAU%20Planetary%20Gazetteer IAU Planetary Gazetteer] as an "[/landing%20site%20name astronaut-named feature], Apollo 15 site," approved in 1973. The list of approved names on which it appeared was not actually published until [/IAU%20Transactions%20XVIB 1976]
- In the geologist-named sense "Apennine Front" has a meaning similar to the Rocky Mountain Front on Earth. In the IAU-adopted sense, according to [/IAU%20Transactions%20XVIB IAU Transactions XVIB], the official meaning is: "the explored foothills of [/Mons%20Hadley%20Delta Hadley Delta]".
- The origin of the diameter of 6 km that currently appears in the [/IAU%20Planetary%20Gazetteer IAU Planetary Gazetteer] is unknown. - JimMosher JimMosher
