A belief that the earth is hollow and inhabited within has caused a Provo man to plan an expedition to the North Pole and possibly to the earth's interior. Steve Currey owns an expedition company in Provo. For over forty years he has organized fly-fishing, kayaking, river rafting and trekking trips around the world. Many locations of his trips are exotic and fascinating, but his next destination is something way out of the ordinary.Currey was contacted by Rodney Cluff, author of "World Top Secret: Our Earth is Hollow," to organize an expedition to the interior of the earth. In his book, Cluff explains the theory of the hollow earth.There is no guarantee the expedition will find anything, but if nothing else, the people will get to go to the North Pole and the Siberian Islands, Currey said. Currey has chartered a nuclear icebreaker with the capacity for 108 passengers for the purpose of taking a group to find the polar opening. The expedition is scheduled for June 26 to July 19, 2005.Currey said people from all over the world have expressed interest in going on the expedition."I am getting three to four calls a day about it," Currey said. Passengers will have to come up with the funds to pay for the expedition. Costs range from $18,950 to $20,950 per person.According to a survey done by LDS author R. Clayton Brough, 4 percent of the LDS population believes in the hollow earth theory and that it is a probable explanation for the location of the lost 10 tribes. Cluff has been investigating the theory for years. "I firmly believe there is a substantial amount of scientific, historical and scriptural evidence to support the theory," he said.
