Rock Lake (Washington)
Rock Lake is the deepest and largest of all scabland lakes left behind from the Missoula Floods, and holds that distinction for all of eastern Washington. At its deepest, it is more than deep, although the official measurement is uncertain. The lake is over long and averages in width, and is accessible via a solitary landing area located on the south end. The rest of the shoreline is inaccessible to vehicles, other than a few private properties. Located approximately south of Cheney, Rock Lake is in a moderately remote location. Other towns in the area include Sprague, St. John, and Rosalia, although all are a number of miles away. Rock Lake receives the majority of its water from Rock Creek, which further downstream is a tributary of the Palouse River, as well as Negro Creek. The lake is approximately long and wide and has a wildly varying depth with steep drop offs that reach over 300 feet. About half a mile from the boat launch, the lakes characteristic geography can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitman County, Washington
Whitman County is a county located in the U.S. state of Washington. As of the 2020 census, the population was 47,973. The county seat is Colfax, and its largest city is Pullman. The county was formed from Stevens County in 1871. It is named after Marcus Whitman, a Presbyterian missionary who, with his wife Narcissa, was killed in 1847 by members of the Cayuse tribe. Whitman County comprises the Pullman, Washington Metropolitan Statistical Area. History The area delineated by the future Washington state boundary began to be colonized at the start of the nineteenth century, both by Americans and Canadians. However, the majority of Canadian exploration and interest in the land was due to the fur trade, whereas American settlers were principally seeking land for agriculture and cattle raising. The Treaty of 1818 provided for dual control of this area by US and Canadian government officials. During this period, the future Washington Territory was divided into two administrativ ...

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Rail Trail
A rail trail is a shared-use path on railway right of way. Rail trails are typically constructed after a railway has been abandoned and the track has been removed, but may also share the right of way with active railways, light rail, or streetcars (rails with trails), or with disused track. As shared-use paths, rail trails are primarily for non-motorized traffic including pedestrians, bicycles, horseback riders, skaters, and cross-country skiers, although snowmobiles and ATVs may be allowed. The characteristics of abandoned railways—gentle grades, well-engineered rights of way and structures (bridges and tunnels), and passage through historical areas—lend themselves to rail trails and account for their popularity. Many rail trails are long-distance trails, while some shorter rail trails are known as greenways or linear parks. Rail trails around the world Americas Bermuda The Bermuda Railway ceased to operate as such when the only carrier to exist in Bermuda folded in 1948. ...

John Wayne Pioneer Trail
The Palouse to Cascades State Park Trail, formerly known as the John Wayne Pioneer Trail and the Iron Horse Trail, is a rail trail that spans most of the U.S. state of Washington. It follows the former railway roadbed of the Chicago, Milwaukee, St. Paul & Pacific Railroad (Milwaukee Road) for across two-thirds of the state, from the western slopes of the Cascade Mountains to the Idaho border. The former Milwaukee Road roadbed was acquired by the state of Washington via a quitclaim deed, and is used as a non-motorized recreational trail managed by the Washington State Parks and Recreation Commission and by the Washington State Department of Natural Resources. State legislation "railbanked" the corridor with provisions that allow for the reversion to railroad usage in the future. History The trail was originally a railroad line which was decommissioned in 1980. Afterwards, establishing a public right-of-way trail on the land was championed by various people and organizations, es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except ...

Bluegill
The bluegill (''Lepomis macrochirus''), sometimes referred to as "bream", "brim", "sunny", or "copper nose" as is common in Texas, is a species of North American freshwater fish, native to and commonly found in streams, rivers, lakes, ponds and wetlands east of the Rocky Mountains. It is the type species of the genus ''Lepomis'' (true sunfish), from the family Centrarchidae (sunfishes, crappies and black basses) in the order Perciformes (perch-like fish). Bluegills can grow up to long and about . While their color can vary from population to population, they typically have a very distinctive coloring, with deep blue and purple on the face and gill cover, dark olive-colored bands down the side, and a fiery orange to yellow belly. They are omnivorous and will consume anything they can fit in their mouth, but mostly feed on small aquatic insects and baitfishes. The fish are important prey for bass, other larger sunfish, northern pike and muskellunge, walleye, trout, herons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crappie
Crappies () are two species of North American freshwater fish of the genus ''Pomoxis'' in the family Centrarchidae (sunfishes). Both species of crappies are popular game fish among recreational anglers. Etymology The genus name ''Pomoxis'' literally means "sharp cover", referring to the fish's spiny gill covers (opercular bones). It is composed of the Greek (, cover) and (, "sharp"). The common name (also spelled ''croppie'' or ''crappé'') derives from the Canadian French , which refers to many different fishes of the sunfish family. Other names for crappie are papermouths, strawberry bass, speckled bass or specks (especially in Michigan), speckled perch, white perch, crappie bass, calico bass (throughout the Middle Atlantic states and New England), and Oswego bass. In Louisiana, it is called sacalait ( frc, sac-à-lait, ), seemingly an allusion to its milky white flesh or silvery skin. The supposed French meaning is, however, folk etymology, because the word is ultim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Kolk Lake
A kolk (colc) is an underwater vortex created when rapidly rushing water passes an underwater obstacle in boundary areas of high shear. High-velocity gradients produce a violently rotating column of water, similar to a tornado. Kolks can pluck multiple-ton blocks of rock and transport them in suspension for thousands of metres. Kolks leave clear evidence in the form of plucked-bedrock pits, called rock-cut basins or kolk lakes and downstream deposits of gravel-supported blocks that show percussion but no rounding. Examples Kolks were first identified by the Dutch, who observed kolks hoisting several-ton blocks of riprap from dikes and transporting them away, suspended above the bottom. The Larrelt kolk near Emden appeared during the 1717 Christmas flood which broke through a long section of the dyke. The newly formed body of water measured roughly 500 × 100 m and was 25 m deep. In spite of the repair to the dyke, another breach occurred in 1721, which produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palouse River
The Palouse River is a tributary of the Snake River in Washington (state), Washington and Idaho, in the Northwestern United States, northwest United States. It flows for U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed May 3, 2011 southwestwards, primarily through the Palouse region of southeastern Washington. It is part of the Columbia River Drainage Basin, Columbia River Basin, as the Snake River is a tributary of the Columbia River. Its canyon was carved out by a fork in the catastrophic Missoula Floods of the previous ice age, which spilled over the northern Columbia Plateau and flowed into the Snake River, eroding the river's present course in a few thousand years. Course The Palouse River flows from North Central Idaho, northern Idaho into southeast Washington through the Palouse region, named for the river. The river originates in Idaho in northeastern Latah County, Idaho, Latah County, in the Hoodoo Mountains in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
