One hundred years ago yesterday marked the 100th Anniversary of the opening of the Panama Canal. The building of the canal has a long and interesting history and represents one of the major engineering feats of modern man. France started work on the project in 1881 but stopped work because of the high mortality rate from tropical disease. The United States took over the project in 1904. The canal took an entire decade to complete. The canal cuts through the Isthmus of Panama and connects the Pacific Ocean to the Caribbean Sea via 48 miles of water and a series of locks. Last December, I was on board the National Geographic Sea Bird as the National Geographic Photography Expert for the Costa Rica and Panama Expedition. Our final adventure in Panama was to pass through the entire canal, including spending some time on Isla Barro Colorado at the Smithsonian Tropical Research Institute. Our route took us through the canal from the Pacific to the Caribbean. It was a truly remarkable experience. Here are some pictures to illustrate our transit. Enjoy!
