Context: "Orphans of the Helix" is a 46-page science fiction short story by American writer Dan Simmons, set in his Hyperion Cantos fictional universe (one of three, the others being "Remembering Siri", a story which is also a chapter of "Hyperion", and "The Death of a Centaur", which deals with an early and allegorical version of either "The Fall of Hyperion" or "Endymion").  It was first published in the anthology "Far Horizons" in 1999. Mount Sacagawea is the eighth-highest peak in the U.S. state of Wyoming and the seventh-highest in the Wind River Range.  It was named after Sacagawea, the young Lemhi Shoshone woman who accompanied the Lewis and Clark Expedition as an interpreter and guide.  The Upper Fremont Glacier is located southeast and the Sacagawea Glacier is northeast of the mountain.  Straddling the Continental Divide, Mount Sacagawea is one mile (1.6 km) northwest of Fremont Peak. Museum of Human Beings, included in the National American Indian Heritage Month Booklist, November 2012 and 2013 is a novel written by Colin Sargent, which delves into the heart-rending life of Jean-Baptiste Charbonneau, the son of Sacagawea.  Sacagawea was the Native American guide, who at 16 led the Lewis and Clark expedition. Far Horizons is a historic house located on Learned Road in Dublin, New Hampshire.  Henry Dwight Learned, a New Hampshire state senator, built the house on his family's farm in 1898–99.  The Queen Anne house features an octagonal turret on one of its front corners, verandahs on two sides, and a hipped and gabled roof.  Physicist Robert Kraichnan later lived in the house; Kraichman put an addition on the house in 1968. Legends: Short Novels by the Masters of Modern Fantasy is a 1998 anthology of 11 novellas (short novels) by a number of English-language fantasy authors, edited by Robert Silverberg.  All the stories were original to the collection, and set in the authors' established fictional worlds.  The anthology won a Locus Award for Best Anthology in 1999.  Its science fiction equivalent, "Far Horizons", followed in 1999. Otter Woman (born 1786-1788, died before 1814) was a Shoshone woman who was wife of a French-speaking trader and interpreter named Toussaint Charbonneau.  Otter Woman was likely stolen by the Hidatsa and purchased by Charbonneau, who is best known as the husband of Sacagawea.  At the time of Sacagawea’s abduction and sale to Charbonneau, Otter Woman was already living with the trapper as his wife.  Charbonneau and Sacagawea were to gain fame as part of the Lewis and Clark expedition that was supported by the Corps of Discovery. Temptation is a novella by David Brin which was published in 1999 in the anthology "Far Horizons: All New Tales from the Greatest Worlds of Science Fiction", ed.  by Robert Silverberg The Far Horizons is a 1955 American western film directed by Rudolph Maté, starring Fred MacMurray, Charlton Heston, Donna Reed and Barbara Hale.  It is about an expedition led by Lewis and Clark, which is sent to survey the territory that the United States has just acquired in the Louisiana Purchase from France.  They are able to overcome the dangers they encounter along the way with the help of a Shoshone woman named Sacagawea.  This is currently the only major American motion picture on the Lewis and Clark expedition (although there have been television documentaries on the subject).  Many details are fictional, and the minor scene where the group reaches the Pacific Ocean reflects the low budget of the film. Speedtalk is a fictional constructed language and key plot device in Robert A. Heinlein's novella "Gulf" (1949).  Speedtalk is a logic-based language with complex syntax, minimal vocabulary, and a rich phoneme inventory (written with letters such as œ, ħ, ø, and ʉ); it would make both communication and thought more efficient and precise.  A single phoneme indicates a word, so a "word" indicates a sentence.  In the only example given, a "word" means ""The far horizons draw no nearer."" ""Sacajawea" redirects here.
