Mount Johnson (Washington)
Mount Johnson is a summit in the Olympic Mountains and is located in Jefferson County, Washington, Jefferson County of Washington (U.S. state), Washington state. It is situated within Olympic National Park, and is set within the Daniel J. Evans Wilderness. At high, Mount Johnson is the fourth-highest peak of the Olympic Mountains, after Mount Olympus (Washington), Mount Olympus, Mount Deception (Washington), Mount Deception, and Mount Constance. It is the highest peak in The Needles (Olympic Mountains), The Needles range which is a subset of the Olympic range. The nearest higher neighbor is Mount Deception, to the south. Mount Johnson is set in the eastern portion of the Olympic Mountains within the drainage basin of the Dungeness River. This location puts it in the rain shadow of the Olympic Range, resulting in less precipitation than Mount Olympus and the western Olympics receive. History Mount Johnson was given its name based on what was believed to be the first ascent b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 is the highest at ; however, the eastern slopes rise 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. The 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 the Olympic National Forest. The mountains are located in western Washington in the United States, spread out across four counties: Clallam, Grays Harbor, Jefferson and Mason. Physiographically, they are a section of the larger Pacific Border province, which is in turn a part of the larger Pacific Mountain System. Geography The Olympics have the form of a cluster of steep-sided peaks surrounded by heavily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain Shadow
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side. Evaporated moisture from water bodies (such as oceans and large lakes) is carried by the prevailing onshore breezes towards the drier and hotter inland areas. When encountering elevated landforms, the moist air is driven upslope towards the peak, where it expands, cools, and its moisture condenses and starts to precipitate. If the landforms are tall and wide enough, most of the humidity will be lost to precipitation over the windward side (also known as the ''rainward'' side) before ever making it past the top. As the air descends the leeward side of the landforms, it is compressed and heated, producing foehn winds that ''absorb'' moisture downslope and cast a broad "shadow" of dry climate region behind the mountain crests. This climate typically takes the form of shrub–steppe, xeric shrublands or even deserts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Jefferson County, Washington
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Martin Peak (Olympic Mountains)
Martin Peak is a mountain summit in the Olympic Mountains and is located in Jefferson County of Washington state. It is located within Olympic National Park. At high, Martin Peak is the seventh-highest peak of the Olympic Mountains, and the second-highest peak in The Needles range, which is a subset of the Olympic range. Its nearest higher neighbor is Mount Johnson, to the north-northwest. Precipitation runoff from this peak drains west into headwaters of Gray Wolf River, or east into Royal Creek, both of which are part of the Dungeness River drainage basin. Martin Peak was given its name based on the first ascent in 1940 by George W. Martin (1901–1970), and Elvin Johnson. Climate Martin Peak is located in the marine west coast climate zone of western North America. Weather fronts originating in the Pacific Ocean travel northeast toward the Olympic Mountains. As fronts approach, they are forced upward by the peaks ( orographic lift), causing them to drop their moist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweat Spire
Sweat Spire is a 7,580-foot-elevation (2,310 meter) summit located in the Olympic Mountains, in Jefferson County of Washington state. It is situated within Olympic National Park, and is set within the Daniel J. Evans Wilderness. It is part of The Needles range, which is a subset of the Olympic range. The nearest higher peak is Mount Johnson, to the southwest, and Gasp Pinnacle (7,520 ft) is to the immediate north. The spire is in the rain shadow of the Olympic Range, resulting in less precipitation than Mount Olympus and the western Olympics receive. Precipitation runoff from the mountain drains east into Royal Creek, and west into Gray Wolf River, which are both within the drainage basin of the Dungeness River. Topographic relief is significant as the east aspect rises over 2,400 feet (730 m) above Royal Basin in approximately one mile. The first ascent of the 200-foot-tall spire was made in 1962 by Hilton Keith, Joel Merkel, Joe Munson, and Jim Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movement ...

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Grea ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Weather Front
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients are known as dry lines can trigger severe weather. Some fronts produce no precipitation and little cloudiness, although there is invariably always a wind shift. Cold fronts generally move from west to east, whereas warm fronts move poleward, although any direction is possible. Occluded fronts are a hybrid merge of the two, and stationary fronts are stalled in their motion. Cold fronts and cold occlusions move faster than warm fronts and warm occlusions because the dense air behind them can lift as well as push ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
