1. No disagreement, except that some 151 appears in the name file and some appear in the subject file:
n82068148 008/11=a 008/14=a 151 _ _ $a England
sh2010015057 008/11=a 008/14=b 151 _ _ $a Tabasco Mountains (Mexico)
2. Yes, see n50000359
151 _ _ $a Sonora (Mexico : State)
751 _ _ $z Mexico $z Sonora (State)
3. Oops, my apologies to my VIAF colleagues, I believe that geographic names are in the works… or at least I was under the impression they were from a discussion I had last night.

Andrew, please see [YZ] below
181 __ $z England and you would NOT find this heading in LCSH. This is issue one. Unfortunately, LC does not create 181 in LCSH (actually I think there are some, but not if it’s a name), instead they create a 781 in the name authority record.
[YZ] MARC/LCSH distinguishes between names 100 and geographic names 151 in their authority record. You'll find all geographic names if you look for 151 records.
So to find the corresponding $z England we need to go to the name authority record 150 England with LCCN n82068148.
[YZ] LCCN n82068148 authority record is for 151 England.
Also Andrew, are you indicating there is a difference between the form of geographic name in 151$a and 781$z -- ?
Currently under id.loc.gov you will not find name authority records, but you can find them at viaf.org.
[YZ] viaf.org does not include geographic names. I just checked there England. makes little sense to mix personal/corporate names with geographic ones. Let's see what Ralph comments.
