An odd site is found in desert north of Yuma. For over 60 years people have been bringing in rocks in order to spell out their names and other messages in the desert. While best viewed from a low flying plane, the site is accessable via 4WD vehicles. Remember that many of these messages date back over 50 years and should not be disturbed. If you want to write your own message, BRING YOUR OWN ROCKS and leave alone the efforts of others.
