California Coast Ranges
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that com ...

Seigler Springs, California
Seigler Springs is a set of springs in Lake County, California around which a resort developed in the 19th century. In the 1930s the resort was expanded, and in 1947 an airport opened nearby.

The thermal springs are about northwest of Howard Springs. They are on a gentle slope on the south side of Seigler Canyon Creek. The higher slopes are covered in lava, and crushed sediments appear below the springs. Below the springs the creek runs east through Seigler Canyon, which is about long, with its head about east of Seigler Springs and its mouth about west of the village of Lower Lake.

Boggs Mountain
Boggs Mountain is a mountain the Mayacamas Mountains in Lake County, California. Part of the mountain holds the Boggs Mountain Demonstration State Forest. About 80% of the trees were burned in the September 2015 Valley Fire. Name In the early days of settlement of Lake County, the mountain was called Harbin Mountain after a settler named James M. Harbin who around 1856 took control of the land occupied by the Harbin Hot Springs, and gave his name to the springs and the mountain. An 1890 description by the State Mineralogist used this name to refer to the mountain. Later the mountain took the name Boggs Mountain. This name honors Henry C. Boggs (1820–1898), an early settler and entrepreneur in Lake County. The name Harbin Mountain survives, referring to a high point above Harbin Hot Springs on a ridge that comes down to the south from Boggs Mountain.

Howard Springs, California
Howard Springs is set of springs turned into a resort in the 1870s in Lake County, California. The resort catered primarily to people interested in the curative powers of the mineral waters. Guests were accommodated in cabins or tents. At one time it had an official post office.

Mediterranean Oak Borer
''Xyleborus monographus'', the ''Mediterranean oak borer'', is a species of ambrosia beetle in the family Curculionidae. It is native to oaks in the regions around the Mediterranean Sea, but since 2019 has been found in California, where the oak trees it infests may be more vulnerable. Native habitat The Mediterranean oak borer is around long. It is native to the regions surrounding the Mediterranean. In these parts of Europe, the Middle East and North Africa the beetle mostly infests dead and dying oak trees. It is found in at least twelve species of oak. As with other ambrosia beetles, it carries symbiotic ambrosia fungi, which it cultivates for food along the boring tunnels. One of these fungi, ''Raffaelea montetyi'', seems linked to wilt disease in cork trees (''Quercus suber'') in Portugal. When the females fly to another tree they carry the fungal spores in their mycangia. The beetle penetrates through thin or cracked bark in the canopy branches. It first invades and kill ...

Valley Oak
''Quercus lobata'', commonly called the valley oak or roble, grows into the largest of California oaks. It is endemic to California, growing in interior valleys and foothills from Siskiyou County to San Diego County. Mature specimens may attain an age of up to 600 years. This deciduous oak requires year-round access to groundwater. Its thick, ridged bark is characteristic and resembles alligator hide. The valley oak's deeply lobed leaves assist in identification. Description The valley oak may surpass in height, with a sturdy trunk possibly exceeding in diameter. The "Henley Oak", in Covelo, California, is the tallest known valley oak, at . The branches have an irregular, spreading and arching appearance that produce a profound leafless silhouette in the clear winter sky. During autumn, the leaves turn a yellow to light orange color but become brown later in the season. In advancing age, the branches assume a drooping characteristic. The tree's pewter-colored rippled bark a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Oak
''Quercus douglasii'', known as blue oak, is a species of oak endemic to (and found only in) 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 mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Lake 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 300 metres (1,000 feet) 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 ...
