Friends,
Certain of you may remember that there once was a letterbox
called "The Hunt for the Temple of Neptune of Atlantis", which was
quite possibly the first underwater letterbox. It was based on lore
that parts of San Francisco were once Tlamco, a city of Atlantis,
which had several temples, the sites of which have been identified in
today's city. That letterbox has vanished and returned to Atlantis.

It appears that another letterbox from Atlantis has appeared, this
time dedicated to the Temple of Saturn, or The Death Temple of
Atlantis. It's located in the place where the original temple was
supposed to have stood.

Here's the link which describes Tlamco, and the whereabouts of the
letterbox:
