2.  The Mysterious Hand Sculpture

Here is a bit more on this unusual work of art from wikipedia:

The sculpture was constructed by the Chilean sculptor Mario Irarrázabal at an altitude of 1,100 meters above sea level. Irarrázabal used the human figure to express emotions like injustice, loneliness, sorrow and torture.^[1] Its exaggerated size is said to emphasize human vulnerability and helplessness.^[1] The work has a base of ironand concrete, and stands 11 metres (36 ft) tall. Funded by Corporación Pro Antofagasta, a local booster organization, the sculpture was inaugurated on March 28, 1992.

3.  Extremely Dry Climate

It is known as the driest non polar desert on the planet.  And because of the climate it is home of some enormous telescopes and potentially the best stargazing in the world.  Is there a connection to the 2003 find and this unusual place?
