There are
probably few ghost towns left anywhere in North America that are as intact as
Kennecott.
It has been abandoned for seventy years now, yet much of it remains. Some of it
is being restored. One building I visited which had not been touched was so
intact it was as if it had only been abandoned a few years. That was the west
barrack (not in sight in the aerial below).
I don't know if this is true, but Kennecott is sometimes referred to as the
largest ghost town in N. America. That may rest on how one defines "ghost town."
In the case of Kennecott, there were no people living there until the late 70s.
I don't believe anyone resides there in the winter, but it is a very active
place in the summer, including a rather elaborate lodge that is designed to fit
in with the rest of the ghost town.
