White River Glacier (Oregon)
White River Glacier is an alpine glacier located on the south slopes of Mount Hood in the U.S. state of Oregon. It ranges in elevation from about . It is among the best known of the twelve glaciers on the mountain, and the lower reaches are a popular destination for Nordic skiing enthusiasts. The glacier is the source of the White River, a tributary of the Deschutes River, and has a long history of washing out the bridge where Oregon Route 35 crosses at . The glacier is a remnant of the massive glaciers that formed during the last ice age and have created White River Canyon. The canyon divides the two largest ski areas on Mount Hood, and is easily seen from many areas of Timberline Lodge ski area, and from the upper southern runs of Mount Hood Meadows. The glacier is bounded on the east by a ridge shared with Newton Clark Glacier and on the west by a ridge shared with Palmer Glacier. The upper glacier forms at the base of ''Steel Cliff'' to the east of an area known as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palmer Glacier
Palmer Glacier is a glacier on the south slopes of Mount Hood in the U.S. state of Oregon. The glacier is situated at an elevation range of , and was named for Joel Palmer, an Oregon pioneer. Palmer Glacier is the most well-known of the twelve glaciers on the mountain, and is a popular destination for snow sport enthusiasts. Some of the lower part is within the Timberline ski area, and can be accessed by Sno-Cat or chairlift, conditions permitting. The glacier is a remnant of the massive glaciers that formed during the last ice age, and is the only location in North America that provides skiing and snowboarding all twelve months of the year. The glacier was considered a snow field until a Mazama committeeThe Mazamas committee consisted of Rodney L. Glisan, L. A. Nelson, Earl A. Marshall, Raymond Smith, Fred McNeil, Everett Philpoe, T. Raymond Conway, and Fred W. Stadter. investigated on October 19, 1924 and determined it was, in fact, a glacier and should be named on maps. F ...

Glaciers Of Hood River County, Oregon
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glacier Terminus
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar way of trac ...

Jökulhlaup
A jökulhlaup ( ) (literally "glacial run") is a type of glacial outburst flood. It is an Icelandic term that has been adopted in glaciological terminology in many languages. It originally referred to the well-known subglacial outburst floods from Vatnajökull, Iceland, which are triggered by geothermal heating and occasionally by a volcanic subglacial eruption, but it is now used to describe any large and abrupt release of water from a subglacial or proglacial lake/reservoir. Since jökulhlaups emerge from hydrostatically sealed lakes with floating levels far above the threshold, their peak discharge can be much larger than that of a marginal or extra-marginal lake burst. The hydrograph of a jökulhlaup from Vatnajökull typically either climbs over a period of weeks with the largest flow near the end, or it climbs much faster during the course of some hours. These patterns are suggested to reflect channel melting, and sheet flow under the front, respectively. Similar pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hood Climbing Accidents
Mount Hood climbing accidents are incidents related to mountain climbing or hiking on Oregon's Mount Hood. As of 2007, about 10,000 people attempt to climb the mountain each year. As of May 2002, more than 130 people are known to have died climbing Mount Hood since records have been kept. One of the worst climbing accidents occurred in 1986, when seven teenagers and two school teachers froze to death while attempting to retreat from a storm. Despite a quadrupling of forest visitors since 1990, the number of people requiring rescue remains steady at around 25 to 50 per year, largely because of the increased use of cell phones and GPS devices. In 2006, 3.4 percent of search and rescue missions were for mountain climbers. In comparison, 20% were for vehicles (including ATVs and snowmobiles), 3% were for mushroom collectors, the remaining 73.6 percent were for skiers, boaters, and participants in other mountain activities. Regardless of route, Mount Hood is a technical climb. It requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zigzag Canyon
Zigzag Glacier is an alpine glacier located on the upper southwest slopes of Mount Hood in the U.S. state of Oregon. It ranges in elevation from with fingers in canyons extending to about , and lies almost entirely within Mount Hood Wilderness. The upper extent is divided from Reid Glacier by Illumination Rock. The top of the glacier is at the foot of Crater Rock. The glacier is bounded on the east by a slight rise shared with the Palmer Glacier (a popular skiing area north of Timberline Lodge since the 1930s) and on the northwest by Reid Glacier. It is the source of the Zigzag River which has erosion, eroded a large, steep canyon named Zigzag Canyon. Below the glacier, its snowfield varies significantly seasonally, varying in length by almost two miles (3.2 km). In 1922, a jökulhlaup originating from Zigzag Glacier as a flow of dark debris came out of a crevasse high on the glacier. It flowed on the surface more than 650 m (2100 ft) before entering another c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hood Wilderness
The Mount Hood Wilderness is a protected wilderness area inside the Mount Hood National Forest, in the U.S. state of Oregon. The area, covering , includes the peak of Mount Hood and its upper slopes, and ranges from temperate rain forests at the lower elevations, to glaciers and rocky ridges at higher elevations. The wilderness wraps around the mountain from west to northeast, and borders Timberline Lodge and Mount Hood Meadows ski lifts on some of the south and east slopes of the mountain. Trails Journeys to the summit are popular. There are opportunities for experienced and novice mountaineers to traverse glaciers, snowfields and steep volcanic soil, and to deal with rapidly changing and difficult to predict weather. More than 10,000 climbers annually make the attempt, making Mount Hood's summit the most visited snowclad peak in America. Numerous trails circle the mountain, from Lolo Pass on the northwest (which the Pacific Crest Trail crosses) to Cloud Cap on the northeast ...
