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] |
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 ...

Rhyacotriton Cascadae
The Cascade torrent salamander (''Rhyacotriton cascadae'') is a species of salamander in the family Rhyacotritonidae. It is endemic to the Pacific Northwest in the United States where it is found from Skamania County in Washington south to Lane County in Oregon on the west slope of the Cascade Mountains. Its natural habitats are temperate forests, rivers, and freshwater springs. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... These salamanders are typically found under rocks and fallen logs. As far as movement, cascade torrent salamander can stay in a small area over very long periods. They also tend to move parallel to the streams they live by. Living by the stream creates a wide range of general lifespan because the salamanders can die from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Peak (Oregon)
Snow Peak (also called Cleveland Rock) is a summit of the Oregon Cascades in the Willamette National Forest. It is located in an undeveloped area with only primitive road access. Fire lookout A fire lookout was present on Snow Peak from August 1912—when a telephone line was installed. A lookout house was built in 1923, and then rebuilt or expanded in 1929. Newspapers and magazines were traditionally delivered to the fire lookout by pack burro, but on August 10, 1939, they were delivered by an accurate airdrop. On the last day of a quiet fire season, September 16, 1948, the lookout itself caught on fire when the departing observer cleaned up and put last of the trash in the stove as he left. The roof burned and fire's heat broke the windows. The Columbus Day Storm of October 1962 damaged the lookout, which was replaced by a new structure that cost $3500 in 1965 (equivalent $ today.). The structure lasted until April 1980 when the remains of the station were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High Prairie (Oregon)
High Prairie is a town in northern Alberta, Canada within Big Lakes County. It is located at the junction of Highway 2 and Highway 749, approximately northeast of Valleyview and west of Slave Lake. History The name describes the nature of the surrounding countryside. A post office opened in 1910. Its early name was Prairie River. In 1914, the alignment of the Edmonton, Dunvegan and British Columbia Railway, later known as the Northern Alberta Railway, was chosen to go through High Prairie instead of Grouard to the northeast. As a result, many residents and businesses from Grouard relocated to High Prairie once the Edmonton, Dunvegan and British Columbia Railway was built. With an estimated population of 600 people, High Prairie was incorporated as a village on April 6, 1945 and subsequently as a town on January 10, 1950. Demographics In the 2021 Census of Population conducted by Statistics Canada, the Town of High Prairie had a population of 2,380 living in 941 o ...

Battle Ax Mountain
Battle Ax is a shield volcano in the West Cascade Range of Oregon. The shield is mostly made of andesite. The summit, which can be reached via the Battle Ax Mountain trail, marks the boundary between the Mount Hood National Forest and the Willamette National Forest as well as the boundary between the Opal Creek Wilderness and the Bull of the Woods Wilderness.

Armet Creek
The armet is a type of combat helmet which was developed in the 15th century. It was extensively used in Italy, France, England, the Low Countries and Spain. It was distinguished by being the first helmet of its era to completely enclose the head while being compact and light enough to move with the wearer. Its use was essentially restricted to the fully armoured man-at-arms. Appearance and origins As the armet was fully enclosing, and narrowed to follow the contours of the neck and throat, it had to have a mechanical means of opening and closing to enable it to be worn. The typical armet consisted of four pieces: the skull, the two large hinged cheek-pieces which locked at the front over the chin, and a visor which had a double pivot, one either side of the skull. The cheek-pieces opened laterally by means of horizontal hinges; when closed they overlapped at the chin, fastening by a spring-pin which engaged in a corresponding hole, or by a swivel-hook and pierced staple. A rein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographic Coordinates
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...
