Little Zigzag River
The Little Zigzag River is a tributary, about long, of the Zigzag River in the U.S. state of Oregon. The Zigzag and Little Zigzag drain the Zigzag Glacier on Mount Hood, a high volcanic peak in the Cascade Range. Their combined waters flow westward to meet the Sandy River near the community of Zigzag. Little Zigzag Falls, a popular hiking destination, is on the river near U.S. Route 26 east of Zigzag. Course The river begins at the head of Little Zigzag Canyon at the southern end of the Zigzag Glacier on Mount Hood. The upper stretches of the river lie within the Mount Hood Wilderness, which is part of the Mount Hood National Forest. To the river's right are the Mississippi Head escarpment, the head of Zigzag Canyon, and the source of the Zigzag River, which also drains Zigzag Glacier. To the Little Zigzag's left is the Palmer Glacier. From its source, the river flows southwest and crosses the Timberline Trail and the Pacific Crest Trail (PCT) slightly west of Timberlin ...

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 ...

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Clackamas County, Oregon
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

Pacific Crest Trail
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie east of the U.S. Pacific coast. The trail's southern terminus is next to the Mexico–United States border, just south of Campo, California, and its northern terminus is on the Canada–US border, upon which it continues unofficially to the Windy Joe Trail within Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington. The Pacific Crest Trail is long and ranges in elevation from roughly above sea level near the Bridge of the Gods on the Oregon–Washington border to at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. Its midpoint is near Chester, California (near Mt. Lassen), where the Sierra and Cascade mountain ranges meet. It was d ...

Timberline Trail
Timberline Trail is a hiking trail around Mount Hood in the U.S. state of Oregon. It is mostly in wilderness but also goes near Timberline Lodge, Cloud Cap Inn (the oldest building on Mount Hood), and Mount Hood Meadows ski area. History The Timberline Trail was constructed in the 1930s by the Civilian Conservation Corps, the majority of their work taking place in the summer of 1934 at a cost of $10,000. Sections of the trail have changed due to damage caused by landslides and washouts since then. In September 1938 a group of hikers completed the entire trail (36 miles at the time) in 47 hours, making local news and increasing awareness of the trail. Hiking the trail The hike is typically completed in three to five days, but some ambitious hikers complete it in one or two days. The trail, Forest Service trail #600, shares with the Pacific Crest Trail and alternates above and below the timberline. The trail is rerouted periodically due to washouts and to avoid sensitiv ...

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 ...

Left Bank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The grade ...
