PANAMA CANAL RAISED-RELIEF MODEL: Aeronautical View of the Panama Canal.
- A fascinating raised-relief model showcasing a bird’s eye view of the Panama Canal, made shortly before this marvel of engineering was opened to revolutionize global shipping. This wonderful raised-relief model of the Panama Canal depicts the channel, dams, reservoirs and locks, as well as the surrounding landscape in great detail. As noted "A careful study of the model will give all the most important facts and figures relating to the greatest achievement of modern time The Panama Canal." In spite of the title ‘aeronautical’, the scene is actually captured from an imaginary suborbital perspective, and certainly well beyond the limits of contemporary aviation. That being said, the captured perspective is quite precise and accurate, as stated "The Model had been made by information furnished by the Isthmian Canal Commission at Washington, D.C, and is therefore authentic." The map, designed by the New York cartographer C.P. Gray, depicts the canal after its final plan had been decided and it was nearing completion, but before it was operational. Working from the Atlantic (left) to the Pacific (right), the canal’s entrance in the Caribbean Sea can be found at Limon Bay and the port city of Colon. At the head of the bay, the Gatun Locks were to lift ships 85 feet (26 metres) up to Gatun Lake, a giant manmade reservoir newly created by the adjacent Gatun Dam. The main shipping channel, delineated by a white line, navigates the lake’s many islands (former hilltops) as it proceeds to the Culebra (or Gaillard) Cut, which is broken thought a broad hill 95 metres (312 feet) in height. Ships were then to descend though the Pedro Miguel and Miraflores Locks before entering the Pacific Ocean near Panama City. The recently relocated Panama Canal Railway skirts the left side of the canal, while a rich and mountainous jungle landscape surrounds the channel on either side. The plan is precisely faithful to what was inevitably constructed, save for the four massive proposed fortifications (two each to be constructed at either end of the canal). Such designs came to be seen as too menacing and unnecessary, and the U.S. inevitably established a far more modest naval and army presence. Moreover, America’s entry into World War I in 1917 ruled out such enormous expenditures. Perhaps sensing the unrealistic nature of the fortifications, the model’s text cautions "The fortifications shown are only proposed." Besides the aforementioned commentary, the text panel of the model features a list of key historical dates for the region and the canal project’s history. It also details a host of fascinating statistics regarding this engineering marvel. The Panama Canal is certainly one of the greatest and most consequential feats of engineering in world history. Over the last century, by allowing ships travelling between the Atlantic and Pacific Oceans to traverse the Panamanian Isthmus, it has saved immeasurable amounts of time, money (and lives), sparing vessels from the long and treacherous voyage rounding South America. The idea for a trans-isthmus canal was not new, as it had first been proposed by Emperor Charles V in 1534. However, it was not until the 19th Century that such a feat was considered to be practically possible. By that time, the word’s great powers were well aware that whomever built and controlled any such canal would be conferred with immense political power and commercial advantage. The French were the first out of the gate. Ferdinand de Lesseps, who had successfully completed the Suez Canal in 1869, ran a venture that proceeded to build a canal across the Panamanian Isthmus in 1881. This plan envisaged a sea level canal, like the Suez (ie. without locks), that involved cutting a channel straight through the low mountains and dense jungle. This project was plagued by mass corruption, technical problems and rampant disease amongst the workers. It failed spectacularly in 1894. The Americans moved in to aggressively to full the vacuum, buyin
