An astronomer on her way to deliver a lecture at the Paranal Observatory in Chile was denied entry upon arrival at the Antofagasta airport. The astronomer was visibly and understandably upset at how she was being treated given her internationally recognized credentials. The only information volunteered by the Immigration Department was that her passport did not conform to the standards imposed by the International Civil Aviation Organization, most notably, the Identity Information Page. Angered at having to go home so early, she vowed to find out why she was denied entry and who was at fault.
Solving this puzzle will allow you to find the cache as well as the reason why the astronomer was denied entry to Chile.
Note that the cache will not be found at the posted coordinates.
