"Down in the Bottomlands" is a novella written by Harry Turtledove. It takes place in an alternative history in which the Point of divergence occurs 5.5 million years ago during the Miocene Epoch when the Atlantic Ocean did not reflood the Mediterranean Sea, as it did in our history. The Mediterranean Basin thus remains dry to the present day in this time line, as a vast sunken desert called the Bottomlands, averaging nearly two kilometers below mean sea level, with summer temperatures reaching well above 40°C and with little or no rainfall, and brine lakes. ==Plot== The story concerns a field biologist working at "Trench Park" named Radnal vez Krobir. He is a citizen of Tartesh, a ''Homo neanderthalensis'' nation which seems to take in much of the west part of the Bottomlands and what in the real world is France and Spain. He is doing a two-year stint as a field guide to tourists from his and other nations who are visiting the Park to see the plants and animals there. During one of those tours, a military officer of the "Kingdom of Morgaf" (real-world Britain and Ireland) is killed by one of the other tourists in his party. Radnal must call higher authorities to investigate the matter, and in the course of their investigation, they determine that the deceased man had a microprint in his effects outlining a plot by another nation to set off a "starbomb" (nuclear weapon) near the "Barrier Mountains" (a range of mountains joining the Sierra Nevada (Spain) and the Rif across where the real-world Strait of Gibraltar is), thereby setting off one of the many geologic faults in the area, knocking a gap in the mountains, and reflooding the Bottomlands to form a new central sea, instigated apparently by Krepalga (a ''Homo sapiens'' nation occupying all or part of the Middle East, which would have benefited by having a real-world-type Mediterranean Sea up to its west border). Radnal and other characters eventually find who killed the Morgaffo officer and with the unwitting help of a koprit bird (similar to a shrike) native to the Park, track down the location of the bomb, where it is defused. Koprit birds apparently have a habit of stealing bright shiny things; it stole the detonator wire from the bomb and used it to decorate its food-hoard bush to attract a mate, as the wire had been disguised as jewelry to smuggle it in past security. The conspirators had sabotaged all the tour party's transport, leaving them stranded far below sea level on the hot dry abyssal plain. This leaves a squad of Tarteshan secret police and police and army with the job of evacuating the tour party, by giving each member a big backpack tank of drinking water and marching them out; partway up to sea level a helicopter finds them and flies the party the rest of the way. (The author realises that in such an ordeal, people cannot live on such small rations as a capful per day from a water bottle, as too often found in stories and in attempted survival in the real world.) The story ends with Radnal being honored by his fellow subjects of the "Hereditary Tyrant" (i.e., King) of Tartesh at a great festival in Tartesh's capital Tarteshem, for saving the Bottomlands from certain destruction where he meets again a woman named Toglo vez Pamdal, who was in his tour party. She had told him she was a "distant collateral relative" of the Hereditary Tyrant but it turns out is actually his niece. They shake hands at the story's conclusion and presumably begin a romantic relationship. The story is told from Radnal's point of view and we see him describe Trench Park and its animals and plants to the tourists. Through these descriptions, we come to understand the unique geography and ecosystem contained within the Bottomlands and its Trench and how animals and plants would have adapted to a desert environment two kilometers below average sea level. We also see how the geography of the area would have been different from our timeline, including things like deep river canyons as the rivers around the Mediterranean would have incised such canyons in their descent down the old continental shelf; hydroelectric dams on such rivers generated 80% of Tartesh's electricity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Down in the Bottomlands」の詳細全文を読む スポンサード リンク
