Hell freezes over as Iapetus receives new feature names:

http://astrogeology.usgs.gov/HotTopics/ind...e-Features.html

Working on a quick map with names. Won't have them all (getting late here in Arizona), but it will have the major craters).

BTW, these group of names include the smallest named crater (officially named anyway): Escremiz is only 60 meters across (somewhere in http://ciclops.org/view/3798/Closest_View_of_Iapetus )

Here be the map:

Thanks VP - nice to see Iapetus becoming Terra Cognita.

So the equatorial ridge is now named, but it's broken up into segments and individual peaks. In order of longitude:

Name CLAT CLON DIAM
Tortelosa Montes 0.0 64.7 294.0 ridge west of "Landslide Crater," (Malun)
Toledo Montes 0.0 136.0 1,100.0 Main part of ridge in mid Cassini
Gayne Mons 0.0 176.0 65.0 \
Valterne Mons 0.0 170.6 50.0 \
Haltile Mons 0.0 190.4 45.0 ----- Individual Voyager Mountains ?
Sorence Mons 0.0 193.7 46.0 /
Cordova Mons 0.0 206.2 85.0 /
Carcassone Montes 0.0 216.7 740.0 Voyager Mountain group?
Seville Mons 0.0 346.3 69.0 Mountain in far Eastern Cassini/Western Roncevaux

They also seem to have split Roncevaux Terra into two parts. Roncevaux Terra is now the northern half of the "white zone". The southern half is called Saragossa Terra or something like that.

I haven't seen this yet, but I expect the "smallest crater" will be the physical point from which longitudes are defined. We normally think of this as being at zero longitude, but it doesn't have to be.

Nice to see the annotated map. Interesting to see that Engelier and Gerin are now being given names
