Maiden Peak (Montana)
Maiden Peak is a steep-sided shield volcano in the Cascade Range of central Oregon. It is the highest point in the distance between Mount Bachelor and Diamond Peak. Ice Age glaciers carved a large cirque into the northeast flank of the mountain, exposing magma which hardened in the volcano's conduits to form the numerous rock pinnacles now found in the upper part of the cirque. The summit of Maiden Peak consists of a steeper cinder cone which sits atop the underlying shield volcano. It is located on the Cascade Crest, which forms the boundary between Lane County and Deschutes County. Also, it is on the boundary between the Deschutes National Forest and the Willamette National Forest. A Forest Service fire lookout tower A fire lookout tower, fire tower or lookout tower, provides housing and protection for a person known as a "fire lookout" whose duty it is to search for wildfires in the wilderness.

Deschutes County, Oregon
Deschutes County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 198,253. The county seat is Bend. The county was created in 1916 out of part of Crook County and was named for the Deschutes River, which itself was named by French-Canadian trappers of the early 19th century. It is the political and economic hub of Central Oregon. Deschutes comprises the Bend, Oregon Metropolitan Statistical Area. Deschutes is Oregon’s fastest-growing and most recently-formed county. History French-Canadian fur trappers of the Hudson's Bay Company gave the name Rivière des Chutes (River of the Falls) to the Deschutes River, from which the county derived its name. On December 13, 1916, Deschutes County was created from the southern part of Crook County. Bend has been the county seat since the county's formation. It was the last county in Oregon to be established. The Shevlin-Hixon Lumber Company also operated within the Bend area proces ...

Deschutes National Forest
The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon. It comprises along the east side of the Cascade Range. In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests. In 1911, parts of the Deschutes National Forest were split off to form the Ochoco and Paulina National Forests, and parts of the Cascade and Oregon National Forests were added to the Deschutes. In 1915, the lands of the Paulina National Forest were rejoined to the Deschutes National Forest. A 1993 Forest Service study estimated that the extent of old growth (economic definition) in the forest was . Within the boundaries of the Deschutes National Forest is the Newberry National Volcanic Monument, containing cinder cones, lava flows, and lava tubes. The Deschutes National Forest as a whole contains in excess of 250 known caves. The forest als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Deschutes County, Oregon
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Volcanoes Of Deschutes County, Oregon
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Cascade Volcanoes
The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over . The arc formed due to subduction along the Cascadia subduction zone. Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper. Some of the major cities along the length of the arc include Portland, Seattle, and Vancouver, and the population in the region exceeds 10 million. All could be potentially affected by volcanic activity and great subduction-zone earthquakes along the arc. Because the population of the Pacific Northwest is rapidly increasing, the Cascade volcanoes are some of the most dangerous, due to th ...

Subduction Volcanoes
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shield Volcanoes Of The United States
A shield is a piece of personal armour held in the hand, which may or may not be strapped to the wrist or forearm. Shields are used to intercept specific attacks, whether from close-ranged weaponry or projectiles such as arrows, by means of active blocks, as well as to provide passive protection by closing one or more lines of engagement during combat. Shields vary greatly in size and shape, ranging from large panels that protect the user's whole body to small models (such as the buckler) that were intended for hand-to-hand-combat use. Shields also vary a great deal in thickness; whereas some shields were made of relatively deep, absorbent, wooden planking to protect soldiers from the impact of spears and crossbow bolts, others were thinner and lighter and designed mainly for deflecting blade strikes (like the roromaraugi or qauata). Finally, shields vary greatly in shape, ranging in roundness to angularity, proportional length and width, symmetry and edge pattern; different s ...
