In 1961, a project named after this region failed to reach this region with CUSS I. That project was led by Walter Munk and organized by the American Miscellaneous Society. More recent attempts to reach this region have used the (*) Chikyu. The Soviet tried to study this region in the Kola Peninsula by drilling the world's deepest hole. This region only reaches the asthenosphere near mid-ocean ridges. Data from a 1909 earthquake led to the discovery of a difference in the speed of P-waves that traveled above and below this region. For 10 point, name this region of the Earth that separates the crust and mantle, named for a Croatian geologist.
