In The Hunger Games, what is the name of the mountain that the people of District 12 mine in?

The Hunger Games takes place in North
America, where the United States used to be; the new nation is named Panem. A terrible
war has decimated the country, perhaps even the world, and so there are only a few small
enclaves of humans left on the continent. Although the specific mountain that District
12 mines is not named, the region is shown in the
text:

District
12 was in a region known as Appalachia. Even hundreds of years ago, they mined coal
here.
(Collins, The Hunger Games, Google
Books)

This places District
12 in the Eastern United States, probably on the West side of the Appalachian Mountain
range. The fan website linked below contains several pieces of information about how
Panem is laid out, as well as with a few maps; in addition, Suzanne Collins reads
Katniss's voice with a Southern accent, meaning that District 12 is probably near the
Southern end of the Appalachian Mountain range.
