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] |
Tributaries Of The San Joaquin River
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...

Rivers Of Amador County, California
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Sutter Creek
Sutter Creek (formerly spelled Sutter's Creek and Suttercreek; formerly named Suttersville) is a city in Amador County, California, United States. The population was 2,501 at the 2010 census, up from 2,303 at the 2000 census. It is accessible via State Route 49. History The community takes its name from nearby Sutter Creek, which in turn has the name of early California developer John Sutter. Sutter's discovery of gold at nearby Coloma in January 1848 triggered the California Gold Rush. After all his workers left him to go on their own hunts for gold, Sutter moved to Mormon Island with a couple of hands. After about two weeks miners flooded the island, so Sutter and his hands left and returned to Sutter Creek. Sutter said: "I broke up the camp and started on the march further south, and located my next camp on Sutter Creek, now in Amador County, and thought that I should be there alone. The work was going on well for a while, until three or four traveling grog-shops surrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Panning
Gold panning, or simply ''panning'', is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome, where gold and other precious metals were extracted from streams and mountainsides using sluices and panning. However, the productivity rate is comparatively smaller compared to other methods such as the rocker box or large extractors, such as those used at the Super Pit gold mine, in Kalgoorlie, Western Australia, which has led to panning being largely replaced in the commercial market. Process Gold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering, and aggressive agita ...

Oregon Ash
''Fraxinus latifolia'', the Oregon ash, is a member of the ash genus '' Fraxinus'', native to western North America. Description ''Fraxinus latifolia'' is a medium-sized deciduous tree that can grow to heights of in height, with a trunk diameter of in its 100−150-year average life span. Oregon ash can grow considerably larger and can have well over a 200-year life span, or become stunted and very small in more dry habitats. It can develop a broad crown, almost as wide as a bigleaf maple (''Acer macrophyllum'') when it grows in the open, but crowns remain narrow when they are part of a denser tree stand, similar to that of red alder (''Alnus rubra''). The bark is distinctive with dark gray–brown, and it will eventually develop a woven pattern of deep fissures and ridges. The compound leaves are pinnate, long, with 5–9 leaflets attached in pairs to a linear stalk and an additional leaflet at the tip. Each leaflet is ovate, long and broad. The leaves are noticeably lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gray Pine
''Pinus sabiniana'' (sometimes spelled ''P. sabineana''), with vernacular names including towani pine, foothill pine, gray pine, bull pine, and digger pine, is a pine endemic to California in the United States. Some sources discourage using the name "digger pine," considering it pejorative ("digger" was a slur commonly used to refer to Indigenous Americans in the Great Basin and California). Description The ''Pinus sabiniana'' tree typically grows to , but can reach feet in height. The needles of the pine are in fascicles (bundles) of three, distinctively pale gray-green, sparse and drooping, and grow to in length. The seed cones are large and heavy, in length and almost as wide as they are long. When fresh, they weigh from , rarely over . The male cones grow at the base of shoots on the lower branches.
