Big Butte Creek
Big Butte Creek is a tributary of the Rogue River in the U.S. state of Oregon. It drains approximately of Jackson County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin. Flowing predominantly west, they meet near the city of Butte Falls. The main stem flows generally northwest until it empties into the Rogue Falls was incorporated in 1911, and remains the only incorporated town within the watershed's boundaries. Big Butte Creek's watershed was originally settled over 8,000 years ago by the Klamath, Upper Umpqua, and Takelma tribes of Native Americans. In the Rogue River Wars of the 1850s, most of the Native Americans were either killed or forced onto Indian reservations. The first non-indigenous settlers arrived in the 1860s, naming the creek after Snowy Butte, an early name for Mount McLoughlin. In the late 19th century, the watershed was primarily used for agriculture and logging. The small city of Butte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount McLoughlin
Mount McLoughlin is a dormant steep-sided stratovolcano, or composite volcano, in the Cascade Range of southern Oregon and within the United States Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc, within the High Cascades sector. A prominent landmark for the Rogue River Valley, the mountain is north of Mount Shasta, and south-southeast of Crater Lake. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. Mount McLouglin's prominence has made it a landmark to Native American populations for thousands of years. McLoughlin consists largely of basaltic andesite. It underwent three major eruptive periods before its last activity took place between 30,000 and 20,000 years ago. It is not currently monitored for activity or deformation. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall and temperature variation between seasons. The Pacific Crest Trail skirts the eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples
Indigenous peoples are culturally distinct ethnic groups whose members are directly descended from the earliest known inhabitants of a particular geographic region and, to some extent, maintain the language and culture of those original peoples. The term ''Indigenous'' was first, in its modern context, used by Europeans, who used it to differentiate the Indigenous peoples of the Americas from the European settlers of the Americas and from the Sub-Saharan Africans who were brought to the Americas as enslaved people. The term may have first been used in this context by Sir Thomas Browne in 1646, who stated "and although in many parts thereof there be at present swarms of ''Negroes'' serving under the ''Spaniard'', yet were they all transported from ''Africa'', since the discovery of ''Columbus''; and are not indigenous or proper natives of ''America''." Peoples are usually described as "Indigenous" when they maintain traditions or other aspects of an early culture that is asso ...

River Mile
A river mile is a measure of distance in miles along a river from its mouth. River mile numbers begin at zero and increase further upstream. The corresponding metric unit using kilometers is the river kilometer. They are analogous to vehicle roadway mile markers, except that river miles are rarely marked on the physical river; instead they are marked on navigation charts, and topographic maps. Riverfront properties are sometimes partially legally described by their river mile. The river mile is not the same as the length of the river, rather it is a means of locating any feature along the river relative to its distance from the mouth, when measured along the course (or navigable channel) of the river. River mile zero may not be exactly at the mouth. For example, the Willamette River (which discharges into the Columbia River) has its river mile zero at the edge of the navigable channel in the Columbia, some beyond the mouth. Also, the river mile zero for the Lower Mississippi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right Bank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The gra ...

Klamath River
The Klamath River (Karuk: ''Ishkêesh'', Klamath: ''Koke'', Yurok: ''Hehlkeek 'We-Roy'') flows through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. It drains an extensive watershed of almost that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upsi ...

Fourmile Lake (Oregon)
Fourmile Lake (or Four Mile Lake) is a reservoir located above sea level in Klamath County, Oregon, United States. It is northeast of Medford. The lake was created when the tall Fourmile Lake Dam was constructed, impounding Fourmile Creek, in the Klamath River watershed. It is located just to the east of Mount McLoughlin, which stands above sea level. The lake is bordered by Sky Lakes Wilderness, and is in the Winema National Forest. History In 1898, the Fish Lake Water Company was established to help irrigate the Rogue Valley. The company proposed create Fourmile Lake and enlarge nearby Fish Lake for added water storage. The Fourmile Lake Dam was constructed in 1906, while Fish Lake was completed in 1908. The two lakes were connected in 1915 by the Cascade Canal, taking water from Fourmile Lake over the Cascade Divide to Fish Lake, supplementing Little Butte Creek. In 1955, the dam was repaired, and a new spillway was added. Statistics Fourmile Lake has an averag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur ...

Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Of Critical Environmental Concern
Areas of Critical Environmental Concern (ACEC) is a conservation ecology program in the Western United States, managed by the Bureau of Land Management (BLM). The ACEC program was conceived in the 1976 Federal Lands Policy and Management Act (FLPMA), which established the first conservation ecology mandate for the BLM. The FLPMA mandate directs the BLM to protect important riparian corridors, threatened and endangered species habitats, cultural and archeological resources, as well as unique scenic landscapes that the agency assesses as in need of special management attention. Criteria To be considered a potential ACEC an area must meet criteria of both relevance and importance. Relevance An area meets the relevance criteria of an ACEC if it contains one or more of the following: *A significant historic, cultural, or scenic value; *A fish or wildlife resource; *A natural process or system (including but not limited to areas supporting rare, endemic, relict, or endangered plant ...

Salmon
Salmon () is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus '' Oncorhynchus'') basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen. Salmon are typically anadromous: they hatch in the gravel beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend on ...
