Crabtree Hot Springs, California
Crabtree Hot Springs is a geological phenomenon in Lake County, California about north of Upper Lake. It is located on private property and closed to the public. It lies at an elevation of 2,257 feet (688 m). There is a cluster of four natural hot springs at this location, in an isolated narrow winding steep walled canyon on the north bank of the Rice Fork of the Eel River, about one fourth mile downriver from its junction with Salt Creek. Three of the hot springs are aligned in one area at a large swimming hole, while the fourth hot spring is about 60 feet (18 m) back upriver. The temperature of the hottest spring is , with a flow rate of about per minute. History About 1875, John Fletcher Crabtree (1824-1915), and sons found the hot springs by following a well used Native American trail. The local Native Americans believed that the water had health-giving qualities, and Crabtree invited whites to the springs for these purported medicinal properties, many of whom had abso ...

Argillaceous Minerals
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2 Si2 O5( OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans since ancient times in agriculture and manufacturing. Properties Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. It is a very common material, and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. Because the individual particles in clay are less than ...

Clear Lake, California
Clearlake is a city in Lake County, California. Clearlake is north-northwest of Lower Lake, at an elevation of . As of the 2020 census, the city had a total population of 16,685, up from 15,250 in 2010. It takes its name from Clear Lake. History The Clearlake post office opened in 1923, "Konocti" then Clearlake Highlands until incorporation in 1981 when the official name became City of Clearlake. The first inhabitants of Clearlake were the Pomo Indians, who named many of the area's features, including Mount Konocti. Beginning in 1821, enslavement and mistreatment by Spanish soldiers and missionaries, Mexican land barons, European settlers, and gold diggers, combined with a lack of natural immunity to European diseases, resulted in a massive wave of deaths. The result of this was massive amounts of land freed up for the white settlers who arrived during the gold rush. Geography Clearlake is located at 38°57'30" North, 122°37'35" West.

Van Arsdale formed the Eel River Power and Irrigation Company and contracted with the city of Ukiah for a hydroelectric generating station to increase electricity supply for the city. A diversion dam was built on the Eel River and a mile-long tunnel was constructed to divert water into the Russian River. A powerhouse was constructed in Potter Valley.

Work Relief Program
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * new technologies and inventions * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * policies of the government * regulation and market Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can influence the availability and cost for money through its monetary p ...

Civilian Conservation Corps
The Civilian Conservation Corps (CCC) was a voluntary government work relief program that ran from 1933 to 1942 in the United States for unemployed, unmarried men ages 18–25 and eventually expanded to ages 17–28. The CCC was a major part of President Franklin D. Roosevelt's New Deal that supplied manual labor jobs related to the conservation and development of natural resources in rural lands owned by federal, state, and local governments. The CCC was designed to supply jobs for young men and to relieve families who had difficulty finding jobs during the Great Depression in the United States Robert Fechner was the first director of this agency, succeeded by James McEntee following Fechner's death. The largest enrollment at any one time was 300,000. Through the course of its nine years in operation, three million young men took part in the CCC, which provided them with shelter, clothing, and food, together with a wage of $30 (equivalent to $1000 in 2021) per month ($25 of ...

Bartlett Springs, California
Bartlett Springs is a set of springs around which a resort was developed in Lake County, California. There were four improved springs, each delivering cool carbonated water with considerable amounts of suspended iron. In 1914 it was the largest such resort in Lake County, capable of accommodating up to 500 guests. There was also a bottling plant designed to maintain the natural carbonation as the bottles were filled and capped. It could fill 10,000 per day during the season from May to October when the roads were passable. Location Bartlett Springs is north of Clearlake Oaks, at an elevation of 2146 feet (654 m). It is near the head of Bartlett Creek, a tributary of Cache Creek. The springs are mostly on the slopes some distance above the resort. The rocks around the springs are altered sandstone, shale and serpentine. Springs The Main Spring or Bartlett Spring is in the northern part of site at the foot of the steep slope. As of 1911 it was surrounded by a cement floor and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efficacious
Efficacy is the ability to perform a task to a satisfactory or expected degree. The word comes from the same roots as ''effectiveness'', and it has often been used synonymously, although in pharmacology a distinction is now often made between efficacy and effectiveness. The word ''efficacy'' is used in pharmacology and medicine to refer both to the maximum response achievable from a pharmaceutical drug in research settings, and to the capacity for sufficient therapeutic effect or beneficial change in clinical settings. Pharmacology In pharmacology, efficacy () is the maximum response achievable from an applied or dosed agent, for instance, a small molecule drug. Intrinsic activity is a relative term for a drug's efficacy relative to a drug with the highest observed efficacy. It is a purely descriptive term that has little or no mechanistic interpretation. In order for a drug to have an effect, it needs to bind to its target, and then to affect the function of this target. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
