full_context: Document 1: Walter Rudin House: The Walter Rudin House is a Frank Lloyd Wright-designed Marshall Erdman prefab building located at 110 Marinette Trail, Madison, Wisconsin. Designed in 1957, it is the first of the only two examples of the second type (known as Prefab #2) of the Marshall Erdman Prefab Houses. This house and the James McBean Residence have the same floor plan and vary only in minor details such as paint color and siting. Construction was completed in June, 1959 and the house was sold to UW-Madison mathematicians Walter and Mary Ellen Rudin. Now, Dr. Thomas Littlefield and Rachel Betzen live there with their two children.
Document 2: Missouri River: The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles (3,767 km) before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km), which includes parts of ten U.S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system.
Document 3: George Furbeck House: The George W. Furbeck House is a house located in the Chicago suburb of Oak Park, Illinois, United States. The house was designed by famous American architect Frank Lloyd Wright in 1897 and constructed for Chicago electrical contractor George W. Furbeck and his new bride Sue Allin Harrington. The home's interior is much as it appeared when the house was completed but the exterior has seen some alteration. The house is an important example of Frank Lloyd Wright's transitional period of the late 1890s which culminated with the birth of the first fully mature early modern Prairie style house. The Furbeck House was listed as a contributing property to a U.S. federal Registered Historic District in 1973 and declared a local Oak Park Landmark in 2002.
Document 4: Yodokō Guest House: The Yodokō Guest House was built as the summer villa for the well-to-do brewer of Sakura-Masamune sake, Tazaemon Yamamura, and is the only surviving Frank Lloyd Wright residence in Japan. The guest house was designed in 1918, and construction was completed in 1924.
Document 5: Rosenbaum House: The Rosenbaum House is a single-family house designed by architect Frank Lloyd Wright and built for Stanley and Mildred Rosenbaum in Florence, Alabama. A noted example of his Usonian house concept, it is the only Wright building in Alabama, and is one of only 26 pre-World War II Usonian houses. Wright scholar John Sergeant called it "the purest example of the Usonian."
Document 6: House VI: House VI, or the Frank Residence, is a significant building designed by Peter Eisenman, completed in 1975. His second built work, the getaway house, located on Great Hollow Road near Bird's Eye Brook in Cornwall, Connecticut (across from Mohawk Mountain Ski Area) has become famous for both its revolutionary definition of a "house" as much as for the physical problems of design and difficulty of use. At the time of construction, the architect was known almost exclusively as a theorist and "paper architect," promulgating a highly formalist approach to architecture he calls "postfunctionalism." Rather than form following function or an aesthetic design, the design emerged from a conceptual process, and remains pinned to that conceptual framework.
Document 7: Lake of the Ozarks: The Lake of the Ozarks is a large reservoir created by impounding the Osage River in the northern part of the Ozarks in central Missouri. Extents of three smaller tributaries to the Osage are included in the impoundment: the Niangua River, Grandglaize Creek, and Gravois Creek. The lake has a surface area of 54,000 acres (220 km) and 1,150 miles (1,850 km) of shoreline, and the main channel of the Osage Arm stretches 92 miles (148 km) from end to end. The total drainage area is over 14,000 square miles (36,000 km). The lake's serpentine shape has earned it the nickname ``The Magic Dragon '', which has in turn inspired the names of local institutions such as The Magic Dragon Street Meet.
Document 8: Geography of Missouri: Missouri river from its mouth at St. Louis to Columbia. This also corresponds to the southernmost extent of glaciation during the Pre-Illinoian Stage which destroyed the remnant plateau to the north but left the ancient landforms to the south unaltered. The Ozark boundary runs southwestward from there towards Joplin at the southeast corner of Kansas. The boundary between the Ozark and lowland regions runs southwest from Cape Girardeau on the Mississippi River to the Arkansas border just southwest of Poplar Bluff. Missouri borders eight other US States, more than any other state except Tennessee, which also borders eight states.
Document 9: Mississippi River: The Mississippi River is the chief river of the second - largest drainage system on the North American continent, second only to the Hudson Bay drainage system. Flowing entirely in the United States (although its drainage basin reaches into Canada), it rises in northern Minnesota and meanders slowly southwards for 2,320 miles (3,730 km) to the Mississippi River Delta at the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth - longest and fifteenth - largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Document 10: Bernard Schwartz House: The Bernard (and Fern) Schwartz House, also known as Still Bend, is a Frank Lloyd Wright-designed house in Two Rivers, Wisconsin. It is considered to be Wright's "Life" magazine "Dream House," and is a rare example of a two-story Usonian house. Wright originally developed the design for the house for "Life" in 1938. The Schwartz House is one of the few Wright homes that allow guests to spend the night. This property is believed to have the oldest, continuously operating in-floor heating system in the country.
Document 11: Mississippi River: The Mississippi River is the chief river of the second - largest drainage system on the North American continent, second only to the Hudson Bay drainage system. The stream is entirely within the United States (although its drainage basin reaches into Canada), its source is Lake Itasca in northern Minnesota and it flows generally south for 2,320 miles (3,730 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and two Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth - longest and fifteenth - largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Document 12: Meramec River: The Meramec River (/ ˈmɛrɪmæk /) is one of the longest free - flowing waterways in Missouri, draining 3,980 square miles (10,300 km) while wandering 218 miles (351 km) from headwaters near Salem to where it empties into the Mississippi River near St. Louis at Arnold and Oakville. The Meramec watershed covers six Missouri Ozark Highland counties -- Dent, Phelps, Crawford, Franklin, Jefferson, and St. Louis -- and portions of eight others -- Maries, Gasconade, Iron, Washington, Reynolds, St. Francois, Ste. Genevieve, and Texas. Between its source and its mouth, it falls 1,025 feet (312 m). Year - round navigability begins above Maramec Spring, just south of St. James. The Meramec's size increases at the confluence of the Dry Fork, and its navigability continues until the river enters the Mississippi at Arnold, Missouri.
Document 13: Eugene A. Gilmore House: The Eugene A. Gilmore House, also known as "Airplane" House, is a Frank Lloyd Wright designed Prairie school home that was constructed in Madison, Wisconsin in 1908. The client, Eugene Allen Gilmore, served as faculty at the nearby University of Wisconsin Law School from 1902 to 1922. It is located within the University Heights Historic District, on Ely Place & Prospect Avenue.
Document 14: Kraus House: The Kraus House, also known as the Frank Lloyd Wright House in Ebsworth Park, is a house in Kirkwood, Missouri designed by architect Frank Lloyd Wright. The house was designed and constructed for Russell and Ruth Goetz Kraus, and the initial design was conceived in 1950. Construction continued until at least 1960 and was never formally completed. The owners lived in the house for about 40 years (Ruth died in 1992).
Document 15: Montana: East of the divide the Missouri River, which is formed by the confluence of the Jefferson, Madison and Gallatin rivers near Three Forks, flows due north through the west-central part of the state to Great Falls. From this point, it then flows generally east through fairly flat agricultural land and the Missouri Breaks to Fort Peck reservoir. The stretch of river between Fort Benton and the Fred Robinson Bridge at the western boundary of Fort Peck Reservoir was designated a National Wild and Scenic River in 1976. The Missouri enters North Dakota near Fort Union, having drained more than half the land area of Montana (82,000 square miles (210,000 km2)). Nearly one-third of the Missouri River in Montana lies behind 10 dams: Toston, Canyon Ferry, Hauser, Holter, Black Eagle, Rainbow, Cochrane, Ryan, Morony, and Fort Peck.
