Forest Park (Portland)
Forest Park is a public municipal park in the Tualatin Mountains west of downtown Portland, Oregon, United States. Stretching for more than on hillsides overlooking the Willamette River, it is one of the country's largest urban forest reserves. The park, a major component of a regional system of parks and trails, covers more than of mostly second-growth forest with a few patches of old growth. About of recreational trails, including the Wildwood Trail segment of the city's 40-Mile Loop system, crisscross the park. As early as the 1860s, civic leaders sought to create a natural preserve in the woods near Portland. Their efforts led to the creation of a municipal park commission that in 1903 hired the Olmsted Brothers landscape architectural firm to develop a plan for Portland's parks. Acquiring land through donations, transfers from Multnomah County, and delinquent tax foreclosures, the city eventually acted on a proposal by the City Club of Portland and combined parcels tot ...

Multnomah County, Oregon
Multnomah County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the county's population was 815,428. Multnomah County is part of the Portland–Vancouver– Hillsboro, OR–WA Metropolitan Statistical Area. Though smallest in area, Multnomah County is the state's most populous county. Its county seat, Portland, is the state's largest city. History The area of the lower Willamette River has been inhabited for thousands of years, including by the Multnomah band of Chinookan peoples long before European contact, as evidenced by the nearby Cathlapotle village, just downstream. Multnomah County (the thirteenth in Oregon Territory) was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of Washington County and the northern part of Clackamas County.

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chugach State Park
Chugach State Park covers 495,204 acres (2,004 square kilometers) immediately east of the Anchorage Bowl in south-central Alaska. Though primarily in the Municipality of Anchorage, a small portion of the park north of the Eklutna Lake area in the vicinity of Pioneer Peak lies within the Matanuska-Susitna Borough. Established by legislation signed into law on August 6, 1970, by Alaska Governor Keith Miller, this state park was created to provide recreational opportunities, protect the scenic value of the Chugach Mountains and other geographic features, and ensure the safety of the water supply for Anchorage. The park, managed by Alaska State Parks, is the third-largest state park in the United States, and consists of geographically disparate areas each with different attractions and facilities.Littlepage, Dean, ''A Falcon Guide Hiking Alaska: A Guide to Alaska's Greatest Hiking Adventures,'' The Globe Pequot Press, Guilford, Connecticut, p. 150 (2006).

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

The Sauvie Island Bridge provides access across the Multnomah Channel from U.S. Route 30 and was completed in June 2008, replacing the first bridge to connect the island to the mainland which was opened on 30 December 1950. The island received the name "Sauvés Island" after Laurent Sauvé dit Laplante, a French-Canadian wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnside Street
Burnside Street is a major thoroughfare of Portland, in the U.S. state of Oregon, and one of a few east–west streets that runs uninterrupted on both sides of the Willamette River. It serves as the dividing line between North Portland and South Portland. Its namesake bridge, Burnside Bridge, is one of the most heavily traversed in Portland. In Gresham between approximately the east 18300 block to Mt. Hood Hwy (and E Powell Blvd/SE Powell Valley Rd), Burnside runs southeast–northwest and is no longer the divide between northeast and southeast on the City of Portland-Multnomah County street grid. Additionally (as you travel southeast), SE Burnside St becomes NW Burnside Road at SE 202nd/NW Birdsdale Ave, and NE Burnside Rd at N Main Ave in Gresham. Burnside Road's eastern terminus is where it meets Mt. Hood Hwy (US-26), E Powell Blvd (US-26), and SE Powell Valley Road.

Cornell Road
Cornell Road is an east–west street and traffic corridor in the Portland metropolitan area, in Multnomah and Washington counties in the U.S. state of Oregon. It crosses the Tualatin Mountains (West Hills) between the Willamette Valley and the city of Portland on the east and the Tualatin Valley and the city of Hillsboro on the west. Cornell Road runs between the western end of Northwest Lovejoy Street in the Hillside neighborhood of Portland to East Main Street in Hillsboro, passing through unincorporated parts of Washington County and through Beaverton on the way. On the west side of NW 185th Ave, it is called ''Northeast'' Cornell Road, as it runs through the northeast quadrant of Hillsboro. Although intended, on its section within the city of Portland, to be a neighborhood collector street with relatively low traffic volumes, it has often functioned as a major traffic street and commuter highway between downtown Portland and its western suburbs. It shares this role with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Willamette Valley
The Willamette Valley ( ) is a long valley in Oregon, in the Pacific Northwest region of the United States. The Willamette River flows the entire length of the valley and is surrounded by mountains on three sides: the Cascade Range to the east, the Oregon Coast Range to the west, and the Calapooya Mountains to the south. The valley is synonymous with the cultural and political heart of Oregon and is home to approximately 70 percent of its population including the five largest cities in the state: Portland, Eugene, Salem, Gresham, and Hillsboro. The valley's numerous waterways, particularly the Willamette River, are vital to the economy of Oregon, as they continuously deposit highly fertile alluvial soils across its broad, flat plain. A massively productive agricultural area, the valley was widely publicized in the 1820s as a "promised land of flowing milk and honey." Throughout the 19th century, it was the destination of choice for the oxen-drawn wagon trains of emigr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of Europe ... this sub-epoch is equivalent to the Astaracian age.
