Mysterious, fascinating, and perfect for tourists. Are we describing geocaching or the Great Pyramid of Giza? Trick question—the answer is both! One of the Seven Wonders of the World, the awesome series of pyramids known as the Giza pyramid complex, or Giza Necropolis, has come to define our sense of historic and remarkable. While we can’t guarantee you’ll find sarcophagi and buried treasure on your trip to Giza, our Geocache of the Week, Casket 4 (GCYZQE), is sure to bring you a smiley and plenty of adventure!
