USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

Glaciers Of Mount Hood
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] |
Zigzag River
The Zigzag River is a tributary, about long, of the Sandy River in the U.S. state of Oregon. The Zigzag and one of its major tributaries, the Little Zigzag River, drain the Zigzag Glacier on Mount Hood, a high volcanic peak in the Cascade Range. Their waters flow westward to meet the Sandy River near the community of Zigzag. The river's flow ranges from . The dramatic topography of the Mississippi Head escarpment dominates the upper Zigzag River, where the Timberline Trail crosses the Zigzag River and the Paradise Park Loop Trail crosses a tributary. Avalanches have necessitated rebuilding of the Timberline Trail switchbacks on the southeast side of the river; the Pacific Crest Trail also follows this route. Seventy-five-foot (23 m) Little Zigzag Falls on the Little Zigzag River is one of the three most popular off-road locations in the Zigzag basin, along with Mirror Lake on the Camp Creek tributary and the area just west of Timberline Lodge under three ski lifts wh ...

Zigzag Glacier
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 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 crevasse, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reid Glacier (Oregon)
Reid Glacier is an alpine glacier located on the west slope of Mount Hood in the U.S. state of Oregon. It ranges in elevation from about . The glacier is the source of the Sandy River. The upper extent of the glacier is known for extensive crevasses. The glacier is a remnant of the massive glaciers that formed during the last ice age. It is bounded on the north by Yokum Ridge which also defines the southern side of Sandy Glacier, and by a ridge on the south bounding the north side of Zigzag Glacier. The eastern and upper reaches of this ridge include Illumination Rock. The uppermost portion of the glacier is below Leuthold Couloir. The glacier lies entirely within Mount Hood Wilderness. Between 1907 and 2004, Reid Glacier lost 35% of its surface area. The glacier terminus has retreated by over the same time period.

Sandy River (Oregon)
The Sandy River is a tributary of the Columbia River in northwestern Oregon in the United States. The Sandy joins the Columbia about upstream of Portland. Course Issuing from Reid Glacier on the southwest flanks of Mount Hood in the Cascade Range, the Sandy River flows generally west and then north for through Clackamas County and Multnomah County to the Columbia River at Troutdale. In its first , the Sandy River flows across Old Maid Flat, north of Zigzag Mountain in the Mount Hood Wilderness of the Mount Hood National Forest. In this initial stretch near the headwaters, it receives Rushing Water Creek from the left, Muddy Fork from the right, then Lost Creek and Horseshoe Creek from the left, and crosses under Lolo Pass Road just before receiving Clear Creek from the right. At about from the mouth, the Zigzag River enters from the left near the unincorporated community of Zigzag. From here the river runs roughly parallel to U.S. Route 26, which is on its left ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwir ...

Sandy Glacier
Sandy Glacier is an alpine glacier located on the west slope of Mount Hood in the U.S. state of Oregon. It extends in elevation from about . The glacier is the source of Muddy Fork, a tributary of the Sandy River. The upper extent of the glacier is known for extensive crevasses. The lower extent was marked by the Sandy Glacier Caves, possibly the largest glacier cave system in the lower 48 U.S. states. The glacier is a remnant of the massive glaciers that formed during the last ice age. It is bounded on the south by Yocum Ridge which also defines the northern side of Reid Glacier, and by a ridge on the north which defines part of the Hood River- Clackamas county border which also bounds the south side of Glisan Glacier. The glacier lies entirely within Mount Hood Wilderness. Sandy Glacier decreased in area by 40% between 1907 and 2004. The glacier terminus has retreated by over the same time period.

West Fork Hood River
The Hood River, formerly known as Dog River, is a tributary of the Columbia River in northwestern Oregon, United States. Approximately long from its mouth to its farthest headwaters on the East Fork, the river descends from wilderness areas in the Cascade Range on Mount Hood and flows through the agricultural Hood River Valley to join the Columbia River in the Columbia River Gorge. It rises in three separate forks on the north side of Mount Hood, within the Mount Hood Wilderness in Hood River County which is approximately east of Portland. West Fork The West Fork, approximately long, rises on northwestern Mount Hood from Ladd Glacier. It flows generally east-northeast and joins the East Fork from the west near Dee. Middle Fork The Middle Fork, approximately long, rises in several short branches on the north slopes of Mount Hood, from Coe Glacier and Eliot Glacier. It flows north through the upper Hood River Valley. East Fork The East Fork, approximately long, rises ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
