Myrtle Creek (South Umpqua River)
Myrtle Creek is a short tributary of the South Umpqua River in Douglas County, Oregon, Douglas County in the U.S. state of Oregon. Its main stem, formed by the confluence of two forks just south of the city of Myrtle Creek, Oregon, Myrtle Creek, is only about long. Its only named tributaries are the two forks, North Myrtle Creek and South Myrtle Creek, each of which is much longer than the main stem. The Myrtle Creek watershed contains one of the largest blocks of land overseen by the Bureau of Land Management in western Oregon. The unbroken forest and its stream network provide habitat for species such as coho salmon and the northern spotted owl as well as clean drinking water for humans. Recreation in the watershed includes hiking, mushroom gathering, camping, horseback riding, and a wide variety of other outdoor activities. In 1990, the City of Myrtle Creek acquired timbers from the former Horse Creek Bridge (McKenzie Bridge, Oregon), Horse Creek Bridge in Lane County, Oregon, ...

Umbellularia
''Umbellularia californica'' is a large hardwood tree native to coastal forests and the Sierra foothills of California, and to coastal forests extending into Oregon. It is endemic to the California Floristic Province. It is the sole species in the genus ''Umbellularia''. The tree was formerly known as ''Oreodaphne californica''. In Yuki, it is called pōl’-cum ōl. In Oregon, this tree is known as Oregon myrtle, while in California it is called California bay laurel, which may be shortened to California bay or California laurel. It has also been called pepperwood, spicebush, cinnamon bush, peppernut tree, headache tree, mountain laurel, and balm of heaven. The tree's pungent leaves have a similar flavor to bay leaves, though stronger, and it may be mistaken for bay laurel. The dry wood has a color range from blonde (like maple) to brown (like walnut). It is considered an excellent tonewood and is sought after by luthiers and woodworkers. The tree is a host of the pathogen tha ...

Covered Bridge
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last over 100 years. In the United States, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration. European and North American truss bridges Typically, covered bridges are structures with longitudinal timber-trusses which form the bridge's backbone. Some were built as railway bridges, using very heavy timbers and doubled up lattice work. In Canada and the U.S., numerous timber covered bridges were built in the late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Th ...

Kingpost Truss
A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below). In aircraft design a strut called a king post acts in compression, similarly to an architectural crown post. Usage in mechanical plant and marine engineering differs again, as noted below. Architecture A king post extends vertically from a crossbeam (the tie beam) to the apex of a triangular truss. The king post, itself in tension, connects the apex of the truss with its base, holding up the tie beam (also in tension) at the base of the truss. The post can be replaced with an iron rod called a king rod (or king bolt) and thus a king rod truss. The king post truss is also called a "Latin truss". In traditional timber framing, a crown post looks similar to a king post, but it is very different structurally: wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neal Lane Bridge
Neal Lane Bridge is a covered bridge in Douglas County in the U.S. state of Oregon. Built by Douglas County for $1,000 in 1939, it is the only covered bridge in Oregon that uses a kingpost truss. At , it is also one of the shortest covered bridges in the state. Other notable features include plank flooring, arched portals, and narrow window openings, as well as a metal roof. The structure has a five-ton weight limit. The bridge carries Neal Lane over South Myrtle Creek near the city of Myrtle Creek. At the time of the bridge construction in 1939, Floyd C. Frear was the county engineer; Homer Gallop was the bridge foreman. The date of construction, according to the Oregon Department of Transportation, has been challenged by an individual who says he worked on the bridge in 1929. The 1929 date is cited in ''Oregon's Covered Bridges'', but the 1939 date is cited in ''Historic Highway Bridges of Oregon''.

North Umpqua River
The North Umpqua River is a tributary of the Umpqua River, about long, in southwestern Oregon in the United States. It drains a scenic and rugged area of the Cascade Range southeast of Eugene, flowing through steep canyons and surrounded by large Douglas-fir forests. Renowned for its emerald green waters, it is considered one of the best fly fishing streams in the Pacific Northwest for anadromous fish. Description It rises in the high Cascades, issuing from Maidu Lake at elevation of in the Mount Thielsen Wilderness, along the Douglas-Klamath county line approximately east of Roseburg. It follows a serpentine course down from the Cascades, westward along the southern side of the Calapooya Mountains. Its upper course passes through the Umpqua National Forest, past Toketee Falls and Steamboat, where it receives Steamboat Creek from the north. It receives the Little River from the south at Glide (the confluence is known as the Colliding Rivers) and joins the South Umpqua fro ...

Little River (North Umpqua River)
The Little River is a tributary of the North Umpqua River, about long, in southwestern Oregon in the United States. The map quadrangles include river mile (RM) markers along the Little River for . The additional length is an estimate based on map scale and ruler. It drains part of the western side of the Cascade Range east of Roseburg, between the North and South Umpqua. Little River rises north of Quartz Mountain in eastern Douglas County in the Umpqua National Forest. It flows west-northwest and joins the North Umpqua from the south at Glide, approximately 12 miles (19 km) east-northeast of Roseburg. The confluence is known as Colliding Rivers because of the nearly head-on angle at which the streams meet. The current Colliding Rivers Information Center was originally the North Umpqua Ranger Station of the Umpqua National Forest. It was built in 1938 by the Civilian Conservation Corps and United States Forest Service (USFS). It was converted to a residence in the 1950s ...

China Ditch
The China Ditch in Douglas County, in the U.S. state of Oregon, was a canal built in part by Chinese laborers to supply water for the hydraulic mining of gold. The Myrtle Creek Consolidated Hydraulic Gold Mining and Manufacturing Company began purchasing land for the ditch in 1890 and was bankrupt by 1894. Portions of the ditch, which carried water from Little River to North Myrtle Creek, remain visible, and an section is listed on the National Register of Historic Places. The Bureau of Land Management maintains a driving loop and hiking trail for touring the ditch and its works. History Many of the homesteaders in the area had been drawn west in the California gold rush and later moved north to begin farming. When gold was discovered in Douglas County, Oregon, in the 1860s, a number of residents returned to mining. In 1889, miners in the area began planning for of new placers around North Myrtle Creek and became convinced that the surrounding hillsides also held signific ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
