Census-designated Place
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities, colonias located along the Mexico–United States border, and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unin ...

2020 United States Census
The United States census of 2020 was the twenty-fourth decennial United States census. Census Day, the reference day used for the census, was April 1, 2020. Other than a pilot study during the 2000 census, this was the first U.S. census to offer options to respond online or by phone, in addition to the paper response form used for previous censuses. The census was taken during the COVID-19 pandemic, which affected its administration. The census recorded a resident population of 331,449,281 in the fifty states and the District of Columbia, an increase of 7.4 percent, or 22,703,743, over the preceding decade. The growth rate was the second-lowest ever recorded, and the net increase was the sixth highest in history. This was the first census where the ten most populous states each surpassed 10 million residents as well as the first census where the ten most populous cities each surpassed 1 million residents. Background As required by the United States Constitution, the U.S. cens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California State Route 49
State Route 49 (SR 49) is a north–south state highway in the U.S. state of California that passes through many historic mining communities of the 1849 California gold rush. Highway 49 is numbered after the "49ers", the waves of immigrants who swept into the area looking for gold, and it is known as the Golden Chain Highway. This roadway begins at Oakhurst, California, Oakhurst, Madera County, California, Madera County, in the Sierra Nevada (U.S.), Sierra Nevada, where it diverges from State Route 41. It continues in a generally northwest direction, weaving through the communities of Goldside and Ahwahnee, before crossing into Mariposa County, California, Mariposa County. State Route 49 then continues northward through the counties of Tuolumne County, California, Tuolumne, Calaveras County, California, Calaveras, Amador County, California, Amador, El Dorado County, California, El Dorado, Placer County, California, Placer, Nevada County, California, Nevada, Yuba County, Califo ...

Serpentine Soil
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials. Serpentine soils exhibit distinct chemical and physical properties and are generally regarded as poor soils for agriculture. The soil is often reddish, brown, or gray in color due to its high iron and low organic content. Geologically, areas with serpentine bedrock are characteristically steep, rocky, and vulnerable to erosion, which causes many serpentine soils to be rather shallow. The shallow soils and sparse vegetation lead to elevated soil temperatures and dry conditions. Due to their ultramafic origin, ser ...

Ponderosa Pine
''Pinus ponderosa'', commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.Safford, H.D. 2013.

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.

California Black Oak
''Quercus kelloggii'', the California black oak, also known as Kellogg oak, is an oak in the red oak section (genus ''Quercus'', section ''Lobatae'', series ''Agrifoliae''), native to western North America. Although genetically separated from them for more than 20 million years, its leaves (though not its fruit) are remarkably similar in appearance to several other members of the red oak section including the red oak ('' Quercus rubra'') and the black oak (''Quercus velutina'') found in eastern and central North America. Description ''Quercus kelloggii'' 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 broad and rounded, with lower branches nearly touching the ground or forming a browse line. In closed stands, the crown is narrow and slender ... [...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] |
Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Mariposa Creek
Mariposa Creek, originally called the Mariposa River, is a creek that has its source in Mariposa County, California. It flows through the town of Mariposa then southwest through the Sierra foothills, into and across the San Joaquin Valley in Merced County, and empties the sloughs of the San Joaquin River south of the city of Merced. History Mariposa Creek was named by the Spanish explorer Gabriel Moraga on September 27, 1806, when his expedition discovered a great cluster of butterflies (''"mariposas"'' in Spanish and Portuguese): :"We named this place Mariposas utterfliesbecause these abounded, especially at night and during the morning. These butterflies became quite a nuisance. Their eagerness to escape the sun's rays was so pronounced that they pursued us closely everywhere and one of them got inside the ear of one of the privates, causing him great discomfort and us much trouble in extracting it." Each year on the first weekend in May, Mariposa residents mark the annual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Po ...
