Information: - A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. - A steam locomotive is a railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible materialusually coal/coke, wood, or oilto produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind. The first steam locomotive, made by Richard Trevithick, first operated on 21 February 1804, three years after the road locomotive he made in 1801. The first practical steam locomotive was built in 1812-13 by John Blenkinsop. - Mason is a city in southwestern Warren County, Ohio, United States, approximately from downtown Cincinnati.

LaMarcus Adna Thompson obtained a patent regarding roller coasters on January 20, 1885, which were made out of wood, but this patent is considerably later than the "Russian mountains" described below. In essence a specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more "inversions" (such as vertical loops) that briefly turn the rider upside down. The track does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably wild mouse roller coasters, run with single cars. - The Ohio River, which streams westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the largest tributary, by volume, of the Mississippi River in the United States. At the confluence, the Ohio is considerably bigger than the Mississippi (Ohio at Cairo: 281,500cuft/s (7,960m/s); Mississippi at Thebes: 208,200cuft/s (5,897m/s)) and, thus, is hydrologically the main stream of the whole river system, including the Allegheny River further upstream. - Cedar Fair, L.P., doing business as the Cedar Fair Entertainment Company, is a publicly traded partnership headquartered at its Cedar Point amusement park in Sandusky, Ohio.

Owned and operated by Cedar Fair, the park first opened in 1972 by the Taft Broadcasting Company in an effort to move and expand Coney Island, a popular resort destination along the banks of the Ohio River that was prone to frequent flooding. After more than $275 million in capital investments, the park features over 80 rides, shows and attractions including fourteen roller coasters and a water park. - A water park or waterpark is an amusement park that features water play areas, such as swimming pools, water slides, splash pads, spraygrounds (water playgrounds), lazy rivers, or other recreational bathing, swimming, and barefooting environments. Water parks in more current states of development may also be equipped with some type of artificial surfing or bodyboarding environment such as a wave pool or FlowRider. - A mine train roller coaster is a steel roller coaster whose trains often depict a set of mine carts, with the forward-most car or portions of it sometimes resembling a small steam locomotive. Most mine train roller coasters are themed in the style of a mine, a Western scene, or simply a mountain range. - An amusement park (sometimes referred to as a funfair) or theme park is a group of entertainment attractions, rides, and other events in a location for the enjoyment of large numbers of people. Amusement parks have a fixed location, as opposed to travelling funfairs and traveling carnivals, and are more elaborate than simple city parks or playgrounds, usually providing attractions meant to cater specifically to certain age groups, as well as some that are aimed towards all ages. Theme parks, a specific type of amusement park, are usually much more intricately themed to a certain subject or group of subjects than normal amusement parks. - Cincinnati is a city in the U.S. state of Ohio that serves as county seat of Hamilton County.
