Intinan (the path of the sun) We have been reading the book "The Mapmaker's Wife" about the first geodesic mission of the French Academy of Sciences in 1736 to find the middle of the world and to determine the world's shape - so we took a trip to both the Intinan (the exact center) and the Middle of the World (where the French explorers determined it was) sites. What an amazing accomplishment for this group of explorers almost 300 years ago! They determined the center of the earth to within 200 meters, enduring incredible hardships and suffering during the 10 year expedition.
