Trinity Mountains (California)
The Trinity Mountains are a subrange of the Klamath Mountains, one of the ranges within the California Coast Ranges and part the greater Pacific Coast Ranges, the coastal mountain system extending from Mexico to Alaska. The Trinity Mountains subrange rises in Siskiyou County and eastern Trinity County, Northern California. They are protected within the Shasta–Trinity National Forest. Geography The Trinity Mountains run in a southwest-northeasterly direction for . The subrange runs between Trinity Lake and Lake Shasta, around northwest of Redding. Peaks of the Trinity Mountains rise to elevations of in the southwest, and to more than in the northeast. Mount Eddy is the highest peak, at 9,037 ft (2,754 m), and is the highest point of the northern segment of the Pacific Coast Ranges within the lower forty-eight states.

Klamath Mountains
The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of Serpentine group, serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemism, endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of th ...

Mountain Ranges Of Trinity County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Benchmark Maps
Map Link was the largest map distributor in North America not affiliated with a major map publisher, and in terms of titles offered (over 100,000), it was the largest map distributor in the world. Until they closed, it was the largest supplier of maps to places outside the US for the Rand McNally retail travel and map stores. Until late 2008, it was the primary source of maps for Barnes & Noble. It continues to supply several other bookstore chains, and has been a major source of maps to map libraries. Map Link was founded in 1984 as Pacific Travelers Supply, a map and travel store in central Santa Barbara. The brick-and-mortar retail business was spun off in the early 1990s, later changed its name to The Travel Store of Santa Barbara, and closed in 2013. Map Link was based in Goleta, California Goleta ( ; ; Spanish for "schooner") is a city in southern Santa Barbara County, California, United States. It was incorporated as a city in 2002, after a long period as the larges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Douglas-fir
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is the tallest tree in the Pinaceae family. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus '' Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-sized to extremely large evergreen trees, tall (although only coast Douglas-firs reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Douglasii
''Quercus douglasii'', known as blue oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. It is California's most drought-tolerant deciduous oak, and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. Description ''Quercus douglasii'' is a medium-sized tree with sparse foliage, generally tall, with a trunk in diameter at breast height. Trunks are typically solitary, but some trees have multiple trunks. The tallest recorded specimen was found in Alameda County, at . The trees grow slowly, about per year. Individual trees over 500 years old have been recorded. The bark is light gray with many medium-sized dark cracks. The blue-green leaves are tough and leathery, deciduous, long, and entire or shallowly lobed. The acorns are long, with a moderately sweet kernel, and mature in 6–7 months from pollination. ''Q. douglasii'' is monoecious and wind-po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Kelloggii
''Quercus kelloggii'', the California black oak or Kellogg oak, is an oak in the red oak section (genus ''Quercus'', section ''Lobatae'', series ''Agrifoliae'') native to western North America. Description ''Quercus kelloggii'' grows from one to several vertical roots which penetrate to bedrock, with large, laterally spreading roots extending off from vertical ones. It also has a number of surface roots. It can reproduce vegetatively with new growth sprouting from the root crown after the tree is top-killed by wildfire, logging, frost, or other events. While individual trees generally have a lifespan between 100 and 200 years, California black oak can live up to 500 years. The tree typically grows from in height and from in diameter. Large trees may exceed in height and diameter, with the record holder measuring tall and thick (in the Siskiyou National Forest in Oregon). The species also grows in shrubby scrub-oak form on poor sites. In open areas, the crown is bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
