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.

Todd Lake (Oregon)
Todd Lake is a natural lake near the crest of the Cascade Range in central Oregon in the United States. The lake covers . It is named in honor of John Y. Todd, an early settler in Central Oregon. Today, the lake and surrounding forest is managed by the United States Forest Service as part of the Deschutes National Forest. The Oregon Department of Fish and Wildlife regularly stocks the lake with brook trout. There is a day-use area and a rustic campground located on the west shore of the lake. In the summer, Todd Lake is a popular outdoor recreation site for picnicking, fishing, hiking, and nature viewing. In the winter, trails in the Todd Lake area are used for cross-country skiing and snowshoeing. History Originally, Todd Lake was called "Lost Lake" because it was difficult for people to find. In the early 20th century, citizens of Bend, Oregon, asked that the name of the lake be changed to avoid confusion with several other Oregon lakes with the same name. In 192 ...

Lava Flows
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Willamette National Forest
The Willamette National Forest is a National Forest located in the central portion of the Cascade Range of the U.S. state of Oregon. It comprises . Over 380,000 acres (694 mi2, 1,540 km2) are designated wilderness which include seven major mountain peaks. There are also several National Wild and Scenic Rivers within the forest. The forest is named for the Willamette River, which has its headwaters in the forest. The forest headquarters are located in the city of Springfield. There are local ranger district offices in McKenzie Bridge, Detroit, Sweet Home, and Westfir. The forest is famous for being at the center of the controversy between the logging industry and the endangered species status of the northern spotted owl. Environmentalists maintain that the forest was aggressively clear-cut for many years threatening a federally listed endangered species. The timber industry contends that the forest can simultaneously provide lumber jobs and wildlife habitat. Sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilderness Area
Wilderness or wildlands (usually in the plural), are natural environments on Earth that have not been significantly modified by human activity or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity. Some governments establish protection for wilderness areas by law to not only preserve what already exists, but also to promote and advance a natural expression and development. These can be set up in preserves, conservation preserves, national forests, national parks and even in urban areas along rivers, gulches or otherwise undeveloped areas. Often these areas are considered important for the survival of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Bachelor
Mount Bachelor, formerly named Bachelor Butte, is a dormant stratovolcano atop a shield volcano in the Cascade Volcanic Arc and the Cascade Range of central Oregon. Named Mount Bachelor because it stands apart from the nearby Three Sisters, it lies in the eastern segment of the central portion of the High Cascades, the eastern segment of the Cascade Range. The volcano lies at the northern end of the long Mount Bachelor Volcanic Chain, which underwent four major eruptive episodes during the Pleistocene and the Holocene. The United States Geological Survey considers Mount Bachelor a moderate threat, but Bachelor poses little threat of becoming an active volcano in the near future. It remains unclear whether the volcano is extinct or just inactive. The Mount Bachelor ski area has operated on the mountain since 1958, and the volcano's summit hosts the Mount Bachelor Observatory. A center of winter recreation, the area offers snowshoeing, snow skiing, snow tubing, and dog sledding, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
