Hoko River
The Hoko River is a river in the U.S. state of Washington (U.S. state), Washington. It originates in the foothills of the Olympic Mountains, and runs about to the Pacific Ocean through a rugged landscape that has been heavily Logging, logged. Its largest tributary is the Little Hoko River, which joins at river mile . The lower of the Hoko River is Estuary, estuarine. The Hoko watershed supports Chinook salmon, chinook, chum salmon, chum, coho, and winter Rainbow trout, steelhead, with over of stream miles that provide suitable spawning habitat. Because the Hoko River, like the nearby Pysht River, is brushy, full of snag (ecology), snags, and often carries tannin stained water, it is known as a "cedar creek". The name Hoko is of Makah people, Makah origin and refers to the large projecting rock at the river mouth. The Hoko River is the namesake of the Late Eocene Hoko River Formation, which was formally described in 1976 by Parke D. Snavely, Jr. et al from outcrops along the ...

Olympic Mountains
The Olympic Mountains are a mountain range on the Olympic Peninsula of the Pacific Northwest of the United States. The mountains, part of the Pacific Coast Ranges, are not especially high – Mount Olympus (Washington), Mount Olympus is the highest summit at ; however, the eastern slopes rise precipitously out of Puget Sound from sea level, and the western slopes are separated from the Pacific Ocean by the low-lying wide Pacific Ocean coastal plain. These densely forested western slopes are the wettest place in the 48 contiguous states. Most of the mountains are protected within the bounds of Olympic National Park and adjoining segments of Olympic National Forest. The mountains are located in western Washington (state), Washington in the United States, spread out across four counties: Clallam County, Washington, Clallam, Grays Harbor County, Washington, Grays Harbor, Jefferson County, Washington, Jefferson and Mason County, Washington, Mason. Physiographically, they are a sectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributary, tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an Fish migration#Classification, anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to Spawn (biology), spawn after living two to three years in the ocean. 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 Fish hatchery, hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except Antarctica.

Hoko River Formation
The Hoko River Formation is a Late Eocene marine sedimentary geologic formation. The formation is exposed in outcrops along the Strait of Juan de Fuca on the Olympic Peninsula in Washington state, USA. It is known for containing numerous fossils of crabs. It overlies the older Lyre Formation and underlies the younger Makah Formation. Geology and stratigraphy The Hoko River Formation consists of sediments deposited on the inner and middle slopes of a deep marine fan system. It is composed primarily of siltstones and some sandstones exposed under and to the south of the main Makah Formation outcrops along the Strait of Juan De Fuca. The type section, as designated by Parke Snavely ''et al.'', is a section which outcrops along the Hoko River, for which the formation is named, and a section which outcrops along Deep Creek. While the Hoko River formation overlies the Lyre Formation in many places, the two formations intertongue in others. The Makah and Hoko River format ...

Late Eocene
The Priabonian is, in the International Commission on Stratigraphy, ICS's geologic timescale, the latest age (geology), age or the upper stage (stratigraphy), stage of the Eocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. ''Priabona florissantius, Priabona'', an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known. History and naming The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona (Monte di Malo), Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. Stratigraphic definition The base of the Priabonian Stage is at the first appearance datum, first appearance of calcareous nannoplankton species ''Chiasmolithus ...

Makah People
The Makah (; Makah: ') are an Indigenous people of the Pacific Northwest Coast living in Washington, in the northwestern part of the continental United States. They are enrolled in the federally recognized Makah Indian Tribe of the Makah Indian Reservation, commonly known as the Makah Tribe. Linguistically and ethnographically, they are closely related to the Nuu-chah-nulth and Ditidaht peoples of the West Coast of Vancouver Island, who live across the Strait of Juan de Fuca in British Columbia, Canada. Etymology and name The Makah people refer to themselves as the ', which translates to somewhere near to "the people who live by the rocks and seagulls". Other thought translations include "the people who live on the cape by the seagulls", and "people of the point", as well as several others. This has sometimes been anglicized as Kwih-dich-chuh-ahtx''.'' The English name, "Makah," is an exonym derived from the S'Klallam language name for the Makah, ''màq̓áʔa''. It m ...

Tannin Stained Water
A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are ''black mud rivers''. There are also black mud estuaries. Blackwater rivers are lower in nutrients than whitewater rivers and have ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was first proposed by Alfred Russel Wallace in 1853 based on water colour, but the types were more clearly defined by chemistry and physics by from the ...

Snag (ecology)
In forest ecology, a snag is a standing dead or dying tree, often missing a top or most of the smaller branches. In freshwater ecology the term ''snag'' refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris. Snags provide habitat for a wide variety of wildlife but pose hazards to river navigation. When used in manufacturing, especially in Scandinavia, they are often called dead wood and in Finland, kelo wood. Forest snags Snags are an important structural component in forest communities, making up 10–20% of all trees present in old-growth tropical, temperate, and boreal forests. Snags and downed coarse woody debris represent a large portion of the woody biomass in a healthy forest. In temperate forests, snags provide critical habitat for more than 100 species of bird and mammal, and snags are often called 'wildlife trees' by foresters. Dead, decaying wood supports a rich comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pysht River
The Pysht River ( ) is a stream in the U.S. state of Washington. It originates near Ellis Mountain in the northern Olympic Mountains on the Olympic Peninsula and flows generally north, emptying into the Strait of Juan de Fuca. The Pysht and nearby Hoko River are the two largest streams flowing into the southwestern portion of the Strait of Juan de Fuca. The watershed of the Pysht River drains a region of industrial forest lands; 98% of the watershed is zoned commercial forestry and the remainder rural. Nearly all of the forests have been logged at least once and most trees are less than thirty years old. The upper portions of the watershed, which feature steep gradients, are owned by the United States Forest Service. The lower reaches, with low gradients, are largely owned by two industrial forest owners. The name of the Pysht River comes from the Clallam (Salishan) ''pəšc't'', perhaps meaning "against the wind or current". Course The Pysht River originates near Ellis Mountain ...

Coho
COHO, short for Coherent Oscillator, is a technique used with radar systems based on the cavity magnetron to allow them to implement a moving target indicator display. Because the signals are only coherent when received, not transmitted, the concept is also sometimes known as coherent on receive. Due to the way the signal is processed, radars using this technique are known as pseudo-coherent radar. COHO can be inexpensively implemented in analog electronics and was widely used in the 1950s into the 1970s. As newer solid-state systems and fully digital processing became inexpensive, COHO became less widely used and is today found only on certain low-cost systems. Description In a basic sense, moving target indication (MTI) systems work by comparing two pulses of a pulse-radar's received signals. Moving targets will shift the "blips" slightly, although this may be too small to see by the operator, especially for long-distance radars where the motion of even fast targets may be too sma ...
