Question:  Melvern, Kansas is along a river that is notorious for what ?
Context: English Landing Park is located along the Missouri river in Parkville, Missouri, United States.  The area the park now sits were once just low water areas of the Missouri River.  It includes a 3-mile jogging/biking trail that follows the river's edge, several shelters for picnics, a soccer field, a baseball diamond, volleyball courts, 2 playgrounds (one for small kids and one for bigger kids).  Recently, a small 9-hole Frisbee golf course has been added around the jogging/biking trail.  There is also a busy set of train tracks that runs along the length of the park.  The area of present-day English Landing Park was bought from the English Brothers by Colonel George S. Park in 1838, who was a veteran of the Texas war of independence.  He purchased a riverboat landing from them as well, and that riverboat landing as well as the present-day park became a civil war port of call for slave trade.  The Power Plant Restaurant, which sits right next to the rail road tracks at the entrance to the park, was built in the mid-19th century as a coal-fired twin-boiler power plant that fed the entire city.  The city itself was founded by Colonel Park in 1844 and by 1850 he had built warehouses and a large stone hotel.  In 1853 he established one of Platte County's earliest newspapers, The Industrial Luminary.  Parkville itself did not become a Civil War battlefield, but there was still mass genocide as numerous slaves tried desperately to escape across the river into Kansas for freedom.  These slaves were buried in three large but unmarked cemeteries in the present-day Misty Woods subdivision.  After the Civil War, the port and the riverboat landing were all but abandoned and the area slowly changed from a bustling port city to what is present-day Parkville. Martin City is a census-designated place, in Jackson County, Missouri along the Missouri and Kansas border.  A small portion dips down into neighboring Cass County.  It was annexed by the City of Kansas City, Missouri in 1963, but was listed separately in the 2010 Census.  Martin City is still very much its own community, retaining its own zip code, post office, school district, and city services.  The Martin City neighborhood is generally defined as being east of the Kansas state line, south of Blue Ridge Boulevard in areas west and north of the Blue River.  In 2010, the population was 686. The Second Dragoon Expedition of 1835 (also called the Dodge Expedition) left Fort Leavenworth, unorganized territory May 29, 1835, charged with contacting the Indian tribes across the Central Plains to the Rockies as far west as the Mexican border.  Traveling first up the Platte River they made contact with the Otoe, Omaha, Grand Pawnee, and Arickaree tribes.  Continuing south along the front range of the Rockies, they reached Bent's Fort on August 6.  At Bent's Fort the expedition held councils with the Arapahoes, Cheyennes, Black Feet, Gros Ventres, and others.  On August 12, 1835 the Dragoons began the return march from Bent's Fort, following the Santa Fe Trail eastward.  They arrived at Council Grove, Kansas the evening of September 8, 1835.  Between Council Grove and Hundred and Ten Mile Creek the expedition experienced its only loss, the death of 23 year old, Private Samuel Hunt on September 11, 1835.  In Colonel Dodge's Journal he wrote, "On the 11th a man of company “A” died—the first death that has occurred on our whole march, and the only severe sickness.  The colonel directed him to be buried on a high prairie ridge, and a stone placed at the head of the grave, with his name and regiment engraved thereon.  Continued the march; crossed the Hundred-and ten-mile creek, and entered upon the dividing ridge between the Kansas and Osage rivers; passed Round and Elm Groves, and arrived at the crossing of the Kansas, at Dunlap's Ferry, on the 15th; crossed the river, and on the 16th arrived at Fort Leavenworth." Henry P. Larrabee (1830 – 19 December 1906), also known as Hank Larrabee, was a 49er and a rancher in the Eel River Valley of Humboldt County, California notorious for his treatment of Indians.  Subsequently he was a sheriff in Montana, a family man, businessman and school board member in Kansas. The Cimarron River extends 698 mi across New Mexico, Oklahoma, Colorado, and Kansas.  The headwaters flow from Johnson Mesa west of Folsom in northeastern New Mexico.  Much of the river's length lies in Oklahoma, where it either borders or passes through eleven counties.  There are no major cities along its route.The river enters the Oklahoma Panhandle near Kenton, crosses the southeastern corner of Colorado into Kansas, re-enters the Oklahoma Panhandle, re-enters Kansas, and finally returns to Oklahoma where it joins the Arkansas River at Keystone Reservoir west of Tulsa, Oklahoma, its only impoundment.  The Cimarron drains a basin that encompasses about 18,927 mi2 . The 2011 Missouri River floods was a flooding event on the Missouri River in the United States.  The flooding was triggered by record snowfall in the Rocky Mountains of Montana and Wyoming along with near-record spring rainfall in central and eastern Montana.  All six major dams along the Missouri River released record amounts of water to prevent overflow which led to flooding threatening several towns and cities along the river from Montana to Missouri; in particular Bismarck, North Dakota; Pierre, South Dakota; Dakota Dunes, South Dakota; South Sioux City, Nebraska, Sioux City, Iowa; Omaha, Nebraska; Council Bluffs, Iowa; Kansas City, Missouri; Jefferson City, Missouri, as well as putting many smaller towns at risk.  According to the National Weather Service, in the second half of the month of May 2011, almost a year's worth of rain fell over the upper Missouri River basin.  Extremely heavy rainfall in conjunction with an estimated 212 percent of normal snowpack in the Rocky Mountains contributed to this flooding event. The Cimarron Hotel is a historic hotel located in Cimarron, a small town located in southwest Kansas, United States.  Cimarron, settled in 1878, was a notorious branch point on the historic Sante Fe Trail.  At Cimarron, the trail divided, one branch heading southwest, the other following the Arkansas River to Bent's Fort (near La Junta, Colorado), then south over Raton Pass.  Cimarron is the first town west of Dodge City on the Atchison, Topeka, and Santa Fe Railroad line. The Marais des Cygnes River ( , , or ) is a principal tributary of the Osage River, about 217 mi long, in eastern Kansas and western Missouri in the United States.  Via the Osage and Missouri rivers, it is part of the watershed of the Mississippi River.  The name "Marais des Cygnes" means "Marsh of the Swans" in French (presumably in reference to the trumpeter swan which was historically common in the Midwest.)  The river is notorious for flash flooding.  The river is referenced in the song "The River" by Chely Wright. Melvern is a city in Osage County, Kansas, United States, along the Marais des Cygnes River.  As of the 2010 census, the city population was 385. The Kansas City Club, founded in 1882 and located in the Library District of Downtown Kansas City, Missouri, USA, was the oldest gentlemen's club in Missouri.  The club began admitting women members in 1975.  Along with the River Club on nearby Quality Hill, it was one of two surviving private city clubs on the Missouri side of Kansas City.  Notable members included Presidents Harry Truman and Dwight D. Eisenhower, General Omar Bradley, and political boss Tom Pendergast.  It ceased operation in 2015.
