Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Bohemia Mountain
Bohemia Mountain is a mountain in the Cascade Range of the U.S. state of Oregon, within the Umpqua National Forest. Its elevation is . A trail traverses the mountain and leads to the summit. There is a location east of the trail's end where on a clear day one can see Mount Shasta, Mount Hood, and other peaks of the Cascades. Camping is available in the area. An abundance of wildflowers and plants bloom on the mountain from late June to mid-August, which attracts butterflies to the area. Ghost town Bohemia City is a ghost town that lies off the trailhead. A few buildings and some mining equipment remain from the original settlement, which consisted of saloons, hotels, and some residences. The area surrounding the mountain was once known as the Bohemia mining district, named after the Czech immigrant James "Bohemia" Johnson, who discovered gold in the area in 1863.

Lane County, Oregon
Lane County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 382,971, making it the fourth-most populous county in Oregon. The county seat is Eugene. It is named in honor of Joseph Lane, Oregon's first territorial governor. Lane County comprises the Eugene, OR Metropolitan Statistical Area. It is the third-largest MSA in Oregon, and the 144th-largest in the country. History Lane County was established on January 29, 1851. It was created from the southern part of Linn County and the portion of Benton County east of Umpqua County. It was named after the territory's first governor, Joseph Lane. Originally it covered all of southern Oregon east to the Cascade Mountains and south to the California border. When the Territorial Legislature created Lane County, it did not designate a county seat. In the 1853 election, four sites competed for the designation, of which the "Mulligan donation" received a majority vote; however, since ...

Cottage Grove, Oregon
Cottage Grove is a city in Lane County, Oregon, United States. Its population was 10,643 at the 2020 census. It is the third largest city in Lane County. It is on Interstate 5, Oregon Route 99, and the main Willamette Valley line of the CORP railroad. History Cottage Grove post office was established in 1855 east of present-day Creswell. It was named by its first postmaster, G. C. Pearce, whose home was in an oak grove. In 1861, the office was moved to the present site of Saginaw; then in the late 1860s, to the southwestern-most part of present-day Cottage Grove, on the west bank of the Coast Fork Willamette River. When the Southern Pacific railroad was built through the area in the 1870s, Cottage Grove station was placed more than half a mile northeast of the post office, on the river's east side. This was the start of a neighborhood dispute that lasted for nearly 20 years. The people living near the post office did not want it moved to the railroad station, so a new office was e ...

Western Cascades
The Western Cascades is a region of the U.S. state of Oregon between the Willamette Valley and the High Cascades. Deposits of Western Cascades age are also found in adjacent southwest Washington state. The range contains many extinct shield volcanoes, cinder cones and lava flows. The range is highly eroded and heavily forested. Geology The region was volcanically active from approximately 35 to 17 million years ago. The province is characterized as an older, deeply eroded volcanic range lying west of the more recent snow-covered High Cascade Range. They range in elevation from on the western margin to on the eastern margin. The Western Cascades began to form 40 million years ago with eruptions from a chain of volcanoes near the Eocene shoreline. As the regional angle of subduction steepened, volcanic activity gradually shifted to the east in the Miocene and Pliocene. The Western Cascades are made up almost entirely of slightly deformed and partly altered volcanic flows an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placer Mining
Placer mining () is the mining of stream bed (Alluvium, alluvial) deposits for minerals. This may be done by open-pit mining, open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in Alluvium, alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup i ...

Sharps Creek (Oregon)
Sharps Creek is a tributary of the Row River in Lane County, in the U.S. state of Oregon. It begins near Bohemia Mountain and the Calapooia Divide of the Cascade Range and flows generally northwest to meet the river. Much of its course lies within the Umpqua National Forest. Sharps Creek enters the Row River at the unincorporated community of Culp Creek, about southeast of Cottage Grove. According to ''Oregon Geographic Names'', Sharps Creek was named for James H. "Bohemia" Sharp, a local prospector and road builder. The "Bohemia" in Sharp's nickname stemmed from another miner, James Johnson, who in 1863 found lode gold deposits on the mountain. Earlier prospectors had found placer gold in the creek in 1858. Johnson was nicknamed "Bohemia" because he had grown up in Bohemia in eastern Europe. He and other miners organized the Bohemia Gold and Silver Mining District (later referred to as the Bohemia mining district) in 1867. The Sharps Creek Recreation Site, overseen by the B ...

Row River
The Row River is a river, approximately long, in Lane County, Oregon, United States. It rises in the Cascade Range and flows into the Coast Fork Willamette River near Cottage Grove. The stream was originally known as the "East Fork Coast Fork", but was later renamed after a dispute (row) between neighbors and brothers-in-law George Clark and Joseph Southwell over "trespassing" livestock. Clark was killed as a result of the row. The name rhymes with "cow" rather than with "slow". A post office named Row River operated from 1911 to 1914 a little north of the present site of Dorena at . Course The Row River, about long, drains a portion of the Umpqua National Forest on the west face of the central Oregon Cascades between Cottage Grove and Oakridge. Its headwaters are near the unincorporated community of Disston, where Layng Creek and Brice Creek join at . The river flows predominately westward. The maps include river mile (RM) markers from the mouth to RM 20 or river kilo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bohemia
Bohemia ( ; cs, Čechy ; ; hsb, Čěska; szl, Czechy) is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction. Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria. Between 1938 and 1945, these border regions were joined to Nazi Germany as the Sudetenland. The remainder of Czech territory became the Second ...

Lode
In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fissure (or crack) in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The current meaning (ore vein) dates from the 17th century, being an expansion of an earlier sense of a "channel, watercourse" in late Middle English, which in turn is from the 11th-century meaning of ''lode'' as a ‘course, way’. The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions (hot spring fluids) deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentation. A third process for ore deposition is as an evaporite. A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining the v ...
