California is one of the top U.S. destinations.

And, one of the treasures that not a lot of people know about is The Valley of the Names.

The Valley of the Names a well-preserved monument filled with signatures, dates, messages and drawings created with rocks.

For 60 years people have been bringing in rocks to spell out their names and other messages in this barren desert in Yuma, Arizona.

It all started, when soldiers trained in the area expressed their feelings by placing stones on a piece of land, hoping that, even if they may never return home, their loved ones would get to see their message.

That tradition continues, people still leave their special note to loved ones today.

Join thousands who’ve done just that by visiting California.
