Fremont–Winema National Forest
The Fremont–Winema National Forest is a United States National Forest formed from the 2002 merger of the Fremont and Winema National Forests. They cover territory in southern Oregon from the crest of the Cascade Range on the west past the city of Lakeview to the east. The northern end of the forests is bounded by U.S. Route 97 on the west and Oregon Route 31 on the east. To the south, the state border with California forms the boundary of the forests. Klamath Falls is the only city of significant size in the vicinity. The forests are managed by the United States Forest Service, and the national forest headquarters are located in Lakeview. Fremont National Forest The Fremont National Forest was named after John C. Frémont, who explored the area for the United States Army Corps of Engineers in 1843. It is located in western Lake and eastern Klamath counties in Oregon and has a land area of . There are local ranger district offices located in Bly, Lakeview, Paisley, a ...

Lake County, Oregon
Lake County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 8,160. Its county seat is Lakeview. The county is named after the many lakes found within its boundaries, including Lake Abert, Summer Lake, Hart Lake, and Goose Lake. Lake County is in the high desert region known as the Oregon Outback, on the northwestern edge of the Great Basin. The county is generally divided between the communities around Lakeview and Paisley to the south and the communities around Christmas Valley, Fort Rock, and Silver Lake to the north. Its economy consists largely of agriculture and natural resource management and extraction. It is home to many large cattle ranches, hay farms, and timber holdings (both public and private), as well as several frontier towns and early 20th-century homesteads. Although lumber was once a primary economic driver in Lake County, today only one mill remains, at Lakeview. History Pre-Columbian Pre-Clovis era c ...

Meadow
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of meadows, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Klamath Basin
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate. Geology and hydrology The Upper Klamath Watershed lies between the Cascade Range and the Basin and Range Province in southern Oregon and northern California. Bedrock strat ...

Crater Lake National Park
Crater Lake National Park is an American national park located in southern Oregon. Established in 1902, Crater Lake is the fifth-oldest national park in the United States and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of Mount Mazama, a destroyed volcano, and the surrounding hills and forests. The lake is deep at its deepest point,Bacon, Charles R.; James V. Gardner; Larry A. Mayer; Mark W. Buktenica; Peter Darnell; David W. Ramsey; Joel E. Robinson (June 2002). "Morphology, volcanism, and mass wasting in Crater Lake, Oregon". Geological Society of America Bulletin 114 (6): 675–692. doi:10.1130/0016-7606(2002)1142.0.CO;2. ISSN 0016-7606. which makes it the deepest lake in the United States, the second-deepest in North America and the ninth-deepest in the world. Crater Lake is often referred to as the seventh-deepest lake in the world, but this former listing excludes the approximately depth of subglacial Lake Vostok in Antarc ...

Lakeview Mining Company
The Lakeview Mining Company was a Uranium mining#Heap leaching, uranium reduction plant north of Lakeview, Oregon, Lakeview, Lake County, Oregon, Lake County, Oregon. The mill began operating in February 1958 and operating until November 1960. The site covered ; of ore were processed, leaving behind large amounts of residual radioactive material. These were moved to an engineered disposal cell in 1986-1988. The plant was built in 1957-1958 for a cost of approximately $3 million, selling the yellow cake to United States Atomic Energy Commission, Atomic Energy Commission. The plant employed approximately 50 workers. Two successful mines were open in the area, Lucky Lass and White King, feeding the Lakeview plant. Seven raffinate ponds across were used for the uranium extraction process, and a uranium tailings pile existed. In 1961 Kerr-McGee purchased the site; it changed hands several times and by 1968 was owned by Atlantic Richfield (ARCO), which began radiation remediation. M ...

Superfund
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the United States Environmental Protection Agency, Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust ...

Uranium Mining In The United States
Uranium mining in the United States produced of U3O8 in 2019, 88% lower than the 2018 production of of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year. Production came from five in-situ leaching plants in Nebraska and Wyoming (Crow Butte, Lost Creek Project, Ross CPP, North Butte, and Smith Ranch-Highland), and one underground mine. From 1949 to 2019, total US production of uranium oxide (U3O8) was 979.9 million pounds (444,500 tonnes). History While uranium is used primarily for nuclear power, uranium mining had its roots in the production of radium-bearing ore from 1898 from the mining of uranium-vanadium sandstone deposits in western Colorado. The 1950s saw a boom in uranium mining in the western U.S., spurred by the fortunes made by prospectors such as Charlie Steen. The United States was the world's leading producer of uranium from 1953 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Contorta
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine zone, subalpine, but is rare in lowland temperate rainforest, rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The Crown (botany), crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches a ...

Old Growth
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance (ecology), disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and Canopy (biology), ...
