Pudding River
The Pudding River is a tributary of the Molalla River in the U.S. state of Oregon. Its drainage basin covers . Among its tributaries are Silver Creek, Butte Creek, Abiqua Creek, and the Little Pudding River. Historically, the Pudding River flowed directly into the Willamette River, and aerial photos dating back to 1936 provide evidence of the Willamette River's confluence with the Pudding River mainstem channel. Currently, it flows directly into the Molalla River near River Mile 1 before joining the Willamette River. Anadromous and resident salmonids use the Lower Pudding River main stem and key tributaries that support the basin's ecosystems. Geology About 24 million years ago at the end of the Oligocene, Oregon had started to look how it is today and the Willamette Bay finally became the Willamette Valley by drying up and being raised above sea level, after assuming a shape much like today's Puget Sound.

Mainstem (hydrology)
In hydrology, a mainstem (or trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest num ...

Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades.

The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major ...

Willamette Valley
The Willamette Valley ( ) is a long valley in Oregon, in the Pacific Northwest region of the United States.

A massively productive agricultural area, the valley was widely publicized in the 1820s as a "promised land of flowing milk and honey."

Ridgeline
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic drainage, Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more Joint (geology), joints where the valleys formed or other chance occurrences. This type of ridge is generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
