Goose Lake Valley
The Goose Lake Valley is located in south-central Oregon and northeastern California in the United States. It is a high valley at the northwestern corner of North America's Great Basin. Much of the valley floor is covered by Goose Lake, a large endorheic lake that straddles the Oregon–California border. Native Americans inhabited the Goose Lake Valley for thousands of years before explorers arrived in the 19th century. The pioneer wagon route known as the Applegate Trail crossed the Goose Lake Valley on its way to southern Oregon. At the south end of Goose Lake, the Lassen Cutoff separated from the Applegate Trail and headed south toward the Sacramento Valley. Today, Lakeview, Oregon, is the largest settlement in the valley. Livestock ranching and lumber mills are the valley's main commercial activity. The Goose Lake Valley offers a number of recreational opportunities including hang-gliding, hunting, fishing, and birdwatching. Geography The Goose Lake Valley ...

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 ...

Birdwatching
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device like binoculars or a telescope, by listening for bird sounds, or by watching public webcams. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1901 by Edmund Selous; ''bird'' was introduced as a verb in 1918. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's '' The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because it ...

Alluvial
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault Block
Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust. Large areas of bedrock are broken up into blocks by faults. Blocks are characterized by relatively uniform lithology. The largest of these fault blocks are called crustal blocks. Large crustal blocks broken off from tectonic plates are called terranes. Those terranes which are the full thickness of the lithosphere are called microplates. Continent-sized blocks are called variously ''microcontinents, continental ribbons, H-blocks, extensional allochthons and outer highs.'' Because most stresses relate to the tectonic activity of moving plates, most motion between blocks is horizontal, that is parallel to the Earth's crust by strike-slip faults. However vertical movement of blocks produces much more dramatic results. Landforms (mountains, hills, ridges, lakes, valleys, etc.) are sometimes formed when the faults have a large v ...

Pit River
The Pit River is a major river draining from northeastern California into the state's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range. The longest tributary of the Sacramento River, it contributes as much as eighty percent of their combined water volume into the Shasta Lake reservoir; the junction of their Shasta Lake arms is northeast of Shasta Dam. The main stem of the Pit River is long, and some water in the system flows to the Sacramento River measuring from the Pit River's longest source. The Pit River drains a sparsely populated volcanic highlands area in Modoc County's Warner Mountains, passing through the south end of the Cascade Range in a deep canyon northeast of Redding. The river is so named because of the semi-subterranean permanent winter homes and large 'sweat houses' that the Pit River Tribe dug, and their pit traps for game that came to water at the river. The river is a popular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abert Lake
Lake Abert (also known as Abert Lake) is a large, shallow, alkali lake in Lake County, Oregon, United States. It is approximately long and wide at its widest point. It is located northeast of the small, unincorporated community of Valley Falls, Oregon. The lake was named in honor of Colonel John James Abert by explorer John C. Fremont during his 1843 expedition into Central Oregon. No fish live in the alkaline waters of the lake; however, its dense population of brine shrimp supports a variety of shorebirds. The lake is an important stop on the bird migration route known as the Pacific flyway. Ancient Lake Chewaucan The arid land around Lake Abert was once lush. During the Pleistocene epoch, vast areas of south-central Oregon were covered by lakes and wetlands. As the last ice age was ending, rain and runoff from melting snow filled the lowlands throughout this region of the Great Basin, creating an immense freshwater lake called Lake Chewaucan. The lake covered at depths ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burns, Oregon
Burns is a city in and the county seat of Harney County, in the U.S. state of Oregon. According to the 2010 census, the population was 2,806. Burns and the nearby city of Hines are home to about 60 percent of the people in the sparsely populated county, by area the largest in Oregon and the ninth largest in the United States.
