Question: Information: - Montana is a state in the Western region of the United States. The state's name is derived from the Spanish word (mountain). Montana has several nicknames, although none official, including "Big Sky Country" and "The Treasure State", and slogans that include "Land of the Shining Mountains" and more recently "The Last Best Place". Montana has a border with three Canadian provinces: British Columbia, Alberta, and Saskatchewan, the only state to do so. It also borders North Dakota and South Dakota to the east, Wyoming to the south, and Idaho to the west and southwest. Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges. Smaller island ranges are found throughout the state. In total, 77 named ranges are part of the Rocky Mountains. The eastern half of Montana is characterized by western prairie terrain and badlands. - Watson Lake is a town in Yukon, Canada located at mile 635 on the Alaska Highway close to the British Columbia border. Population in 2013 was 1,474 (Yukon Bureau of Statistics). The town is named for Frank Watson, an American-born trapper and prospector, who settled in the area at the end of the nineteenth century. - From 1886 to 1920 , steamboats ran on the upper reaches of the Columbia and Kootenay in the Rocky Mountain Trench , in western North America . The circumstances of the rivers in the area , and the construction of transcontinental railways across the trench from east to west made steamboat navigation possible . - A boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water. Small boats are typically found on inland waterways (e.g., rivers and lakes) or in protected coastal areas. However, boats such as the whaleboat were designed for operation from a ship in an offshore environment. In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship). Another less restrictive definition is a vessel that can be lifted out of the water. Some definitions do not make a distinction in size, as bulk freighters long on the Great Lakes are called oreboats. For reasons of naval tradition, submarines are usually referred to as 'boats' rather than 'ships', regardless of their size and shape. Ships are generally distinguished from boats based on their larger size, shape and cargo or passenger capacity. - The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than from the northernmost part of British Columbia, in western Canada, to New Mexico, in the southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges and the Cascade Range and Sierra Nevada which all lie further to the west. - A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law. A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers - they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propellers average of 0.6 and the ability to throw thrust in any direction at any time. Their disadvantages are higher mechanical complexity and higher cost. - The Rocky Mountain Trench, also known as The Valley of a Thousand Peaks or simply the Trench, is a large valley in the northern part of the Rocky Mountains. It is both visually and cartographically a striking physiographic feature extending approximately from Flathead Lake, Montana to the Liard River, just south of the British Columbia-Yukon border near Watson Lake, Yukon. The trench bottom is 3-16km (210 miles) wide and ranges from 600-900 metres (2,0003,000 feet) above sea level. The general orientation of the Trench is an almost uniform 150/330 degree geographic north vector and has become convenient for north/south aviators. - British Columbia (BC) is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains. British Columbia is also a component of the Pacific Northwest and the Cascadia bioregion, along with the U.S. states of Idaho, Oregon, Washington and Alaska. - A steamship, often referred to as a steamer, is an ocean faring seaworthy vessel that is propelled by one or more steam engines that typically drive (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for "paddle steamer" or "SS" for "screw steamer" (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steam ship". Ships powered by internal combustion engines use a prefix such as "MV" for "motor vessel", so it is not correct to use "SS" for most modern vessels. - Flathead Lake (Salish: lqetk ) is the largest natural freshwater lake by surface area that is west of the Mississippi River in the contiguous United States, if one takes Red Lake and Lake of the Woods to be north of the Mississippi River, rather than west of the river. - Yukon (also commonly called the Yukon) is the westernmost and smallest of Canada's three federal territories (the other two are Northwest Territories and Nunavut). The territory is very sparsely populated with its about 35,000 people on almost half a million square kilometres. Whitehorse is the territorial capital and Yukon's only city. - A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'), however these designations are most often used for Steamships. - The Liard River flows through Yukon, British Columbia and the Northwest Territories, Canada. Rising in the Saint Cyr Range of the Pelly Mountains in southeastern Yukon, it flows southeast through British Columbia, marking the northern end of the Rocky Mountains and then curving northeast back into the Yukon and Northwest Territories, draining into the Mackenzie River at Fort Simpson, Northwest Territories. The river drains approximately of boreal forest and muskeg.
