Eldorado National Forest
Eldorado National Forest is a U.S. National Forest located in the central Sierra Nevada mountain range, in eastern California. Geography Most of the forest (72.8%) lies in El Dorado County. In descending order of land area the others counties are: Amador, Alpine, and Placer counties in California; and Douglas County in Nevada with . The forest is bordered on the north by the Tahoe National Forest, on the east by the Lake Tahoe Basin Management Unit, on the southeast by the Humboldt–Toiyabe National Forest, and to the south by the Stanislaus National Forest. Eldorado National Forest headquarters are located in Placerville, California. There are local ranger district offices in Camino, Georgetown, Pioneer, and Pollock Pines. Land ownership A complicated ownership pattern exists. The parcels of other ownership (private or other agency land) are mostly isolated and surrounded on all sides by government land. An opposite pattern occurs outside of the forest boundary, wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Dorado County, California
El Dorado County (), officially the County of El Dorado, is a county located in the U.S. state of California. As of the 2020 census, the population was 191,185. The county seat is Placerville. The County is part of the Sacramento- Roseville-Arden-Arcade, CA Metropolitan Statistical Area. It is located entirely in the Sierra Nevada, from the historic Gold Country in the western foothills to the High Sierra in the east.

Placerville, California
Placerville (, ; formerly Old Dry Diggings, Dry Diggings, and Hangtown) is a city in and the county seat of El Dorado County, California. The population was 10,747 as of the 2020 census, up from 10,389 as of the 2010 census. It is part of the Sacramento–Arden-Arcade– Roseville Metropolitan Statistical Area. History A former Maidu settlement called Indak was located at the site of the town. After the discovery of gold at Sutter's Mill in nearby Coloma, California, by James W. Marshall in 1848 sparked the California Gold Rush, the small town now known as Placerville was known as Dry Diggin's after the manner in which the miners moved cartloads of dry soil to run water to separate the gold from the soil. Later in 1849, the town earned its most common historical name, "Hangtown", because of the numerous hangings that had occurred there. However, there is debate on exactly how many lynchings occurred in the town. The town had no police force (in 1849) and five immigra ...

Desolation Wilderness
The Desolation Wilderness is a federally protected wilderness area in the Eldorado National Forest and Lake Tahoe Basin Management Unit, in El Dorado County, California. The crest of the Sierra Nevada runs through it, just west of Lake Tahoe. History Before European settlement in the mid-19th century, there is evidence this area was used by the Washoe. After, it was known at times as "Devil's Valley," and most often used for cattle grazing. By the end of that century, the first formal step to limiting its development when it was made a Forest Reserve, managed first by the General Land Office, and later, by the US Forest Service. It was set aside as the Desolation Valley Primitive Area in 1931 with an area of . In 1969, it became the Desolation Wilderness after the passage of the Wilderness Act of 1964.Godfrey, Anthony.

Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubicon River (California)
The Rubicon River is a major tributary of the Middle Fork American River in the Sierra Nevada of Northern California, west of Lake Tahoe. Its length is with a watershed of about . The river's headwaters are in the Crystal Range of the Sierra Nevada, within the Eldorado National Forest's Desolation Wilderness. Historically, the Rubicon River was known as the South Fork of the Middle Fork of the American River. Headwaters The Rubicon River originates at near Clyde Lake in El Dorado County. It flows north-northwest for approximately until it reaches Rubicon Reservoir. The river then travels northwest and within of the Rubicon Reservoir is met by Highland Creek, Miller Creek, and the Little Rubicon River. It continues northwest for approximately to Hell Hole Reservoir. Shortly after the river begins flowing southwest from the reservoir, it serves as a border between El Dorado and Placer Counties, and joins the South Fork of the Rubicon River.

Cosumnes River
The Cosumnes River is a river in northern California in the United States. It rises on the western slope of the Sierra Nevada and flows approximately into the Central Valley, emptying into the Mokelumne River in the Sacramento-San Joaquin Delta. The Cosumnes is one of very few rivers in the western Sierra without major dams. The Nature Conservancy's Cosumnes River Preserve is located just upstream from the Delta. Towns and cities along the Cosumnes River include Plymouth, Rancho Murieta, Sloughhouse, Wilton, Elk Grove, and Galt. The California Office of Environmental Health Hazard Assessment has issued aadvisoryregarding fish caught from the body of water. Name The Cosumnes River is thought to have been named as the Mokelumne and Tuolumne rivers were, using the "-umne" suffix meaning "people of". The prefix is derived from the Miwok word "kosum" meaning "salmon". Chinook Salmon runs are rarely, if ever, seen above Rancho Murieta as a result of diversions in the area. M ...

Mokelumne River
The Mokelumne River ( or ; ''Mokelumne'', Miwok for "People of the Fish Net") is a -long river in northern California in the United States. The river flows west from a rugged portion of the central Sierra Nevada (U.S.), Sierra Nevada into the Central Valley (California), Central Valley and ultimately the Sacramento–San Joaquin River Delta, where it empties into the San Joaquin River-Stockton Deepwater Shipping Channel. Together with its main tributary, the Cosumnes River, the Mokelumne drains in parts of five California counties. Measured to its farthest source at the head of the North Fork, the river stretches for . The river is colloquially divided into the Upper Mokelumne River, which stretches from the headwaters to Pardee Reservoir in the Sierra foothills, and the Lower Mokelumne River, which refers to the portion of the river below Camanche Dam. In its lower course, the Mokelumne is used heavily for irrigation and also provides water for the east San Francisco Bay Area t ...

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...

Foothills
Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. Frequently foothills consist of alluvial fans, coalesced alluvial fans, and dissected plateaus. Description Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, but can also border uplands and higher hills. Examples Areas where foothills exist, or areas commonly referred to as the foothills, include the: *Sierra Nevada foothills of California, USA *Foothills of the San Gabriel Valley in Los Angeles County, California, USA *Rocky Mountain Foothills in British Columbia and Alberta, Canada *Silesian Foothills in Silesia, Poland *Sivalik Hills along the Himalayas in the Indian subcontinent * Catalin ...
