Lake Crescent
Lake Crescent is a deep lake located entirely within Olympic National Park in Clallam County, Washington, United States, approximately west of Port Angeles on U.S. Route 101, near the small community of Piedmont. With an official maximum depth of , it is officially the second deepest lake in the state of Washington (after Lake Chelan). A lake-wide bathymetric survey was performed from 2013 to 2014 by Eian Ray and Jeff Engea and the results of this survey show the maximum depth as being . Using GIS statistical analysis, this survey also estimated that the lake contains around of fresh water. Lake Crescent is known for brilliant blue waters and exceptional clarity caused by low levels of nitrogen in the water that inhibit the growth of algae. The lake is located in a popular recreational area and features several trails, including the Spruce Railroad Trail, Pyramid Mountain trail, and the Barnes Creek trail to Marymere Falls. The Spruce Railroad Trail follows the grade ... [...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 (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] |
Landslide
Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation freque ...

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. Introductions to locations outside their nativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anadromous
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...

Elwha River
The Elwha River is a river on the Olympic Peninsula in the U.S. state of Washington (state), Washington. From its source at Elwha snowfinger in the Olympic Mountains, it flows generally north to the Strait of Juan de Fuca. Most of the river's course is within the Olympic National Park. The Elwha is one of several rivers in the Pacific Northwest that hosts all five species of native Pacific salmon (Chinook salmon, chinook, coho salmon, coho, chum salmon, chum, sockeye salmon, sockeye, and pink salmon), plus four Fish migration, anadromous trout species (Rainbow trout, steelhead, coastal cutthroat trout, bull trout, and Dolly Varden char). From 1911 to 2014, dams blocked fish passage on the lower Elwha River. Before the dams, 400,000 adult salmon returned yearly to spawn in of river habitat. Prior to dam removal, fewer than 4,000 salmon returned each year in only of habitat below the lower dam. The National Park Service removed the two dams as part of the $325 million Elwha Ecos ...

Indian Creek (Elwha River)
Indian Creek is a tributary of the Elwha River located in Washington in the United States. Indian Creek flows from Lake Sutherland into the former Lake Aldwell. Historically, Indian Creek supported runs of several anadromous salmon and trout species, including all five species of Pacific Salmon. However, with construction of the Elwha Dam in 1913, fish were blocked from accessing the Pacific Ocean. While the Elwha Dam was in operation, Indian Creek sustained populations of kokanee sockeye salmon, which spawned in Lake Sutherland and migrated to Lake Aldwell to use as their ocean. It also contained stream resident coastal rainbow trout, coastal cutthroat trout, and introduced eastern brook trout. With the removal of the Elwha Dam in 2012, the native salmonids began a return to their anadromous lifestyle, with spawning activities of true anadromous Chinook salmon observed in late 2013.

Valley
A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally ...

Glacial Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
