Trio of Oreanas

As far as I know (with a limited amount of research completed) there are 3 spots in the U.S. named Oreana.

One is pretty much a ghost town.

And the one we call home is actually the largest of the 3.

Oreana, Nevada is supposedly the ghost town, so I'm confused as to why Google is reporting a Post Office there (see above).

Even the spirits need stamps, I guess?

Out for now......
