It flows north-northwest for approximately until it reaches Rubicon Reservoir.

CATARACT
A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry or double vision, halos around light, trouble with bright lights, and trouble seeing at night. This may result in trouble driving, reading, or recognizing faces. Poor vision caused by cataracts may also result in an increased risk of falling and depression. Cataracts cause 51% of all cases of blindness and 33% of visual impairment worldwide. Cataracts are most commonly due to aging but may also occur due to trauma or radiation exposure, be present from birth, or occur following eye surgery for other problems. Risk factors include diabetes, longstanding use of corticosteroid medication, smoking tobacco, prolonged exposure to sunlight, and alcohol. The underlying mechanism involves accumulation of clumps of protein or yellow-brown pigment in the lens that reduces transmission of ...

Placer County, California
Placer County ( ; Spanish for "sand deposit"), officially the County of Placer, is a county in the U.S. state of California. As of the 2020 census, the population was 404,739. The county seat is Auburn. Placer County is included in the Greater Sacramento metropolitan area. It is in both the Sacramento Valley and Sierra Nevada regions, in what is known as the Gold Country. The county stretches roughly 65 miles (105 km) from Sacramento's suburbs at Roseville to the Nevada border and the shore of Lake Tahoe. Etymology The discovery of gold in 1848 brought tens of thousands of miners from around the world during the California Gold Rush. In addition, many more thousands came to provide goods and services to the miners. On April 25, 1851, the fast-growing county was formed from parts of Sutter and Yuba Counties with Auburn as the county seat. Placer County took its name from the Spanish word for sand or gravel deposits containing gold. Miners washed away the gravel, le ...

Rivers Of The Sierra Nevada (United States)
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, ...

Foresthill
Foresthill is a census-designated place (CDP) in Placer County, California, United States. It is part of the Sacramento–Arden-Arcade– Roseville Metropolitan Statistical Area. The population was 1,483 at the 2010 census, down from 1,791 at the 2000 census. History Foresthill is located on a broad ridge between the North and Middle Forks of the American River on the gold-bearing gravel bed of an ancient river. In the spring of 1850, miners came to the Forest Hill Divide in large numbers. There was one route from Auburn through Yankee Jim's and one from Coloma. At the junction of these trails, the Forest House hotel and trading post was built. The height of mining activity in Foresthill began in 1853 after a winter landslide at the head of Jenny Lind Canyon exposed numerous nuggets of gold. The Jenny Lind mine produced about $2,500 of gold a day for a while, up to a total output over $1 million by 1880. The combined production of all the mines in the Forest Hill area ...

Auburn State Recreation Area
Auburn State Recreation Area is a state park unit of California, along of the North and Middle Forks of the American River. The state recreation area (SRA) is situated on the border of Placer and El Dorado Counties in the heart of historic Gold Country. The largest city with close proximity is the city of Auburn. Once teeming with gold mining activity, the area now offers a wide variety of outdoor recreational opportunities. Major recreational uses include trail running, hiking, swimming, boating, fishing, camping, mountain biking, gold panning, horseback riding, road bicycling, and off-highway motorcycle riding. Whitewater recreation is also very popular on both forks of the river, with Class II, III and IV runs. Auburn SRA is also known as the location of a number of endurance races that are hosted throughout the year. History Auburn SRA comprises lands set aside for the proposed Auburn Dam. However a large earthquake at Oroville nearby was found to have been caused by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

This group was on its way to the gold fields in Coloma, California, and it included Francois Gendron, Philibert Courteau, and Claude Chana. The young Chana discovered gold on May 16, 1848. After finding the gold deposits in the soil, the trio decided to stay for more prospecting and mining. Placer mining in the Auburn area was very ...

Loon Lake (California)
Loon Lake is a reservoir in the Eldorado National Forest of El Dorado County, California, United States. The lake is formed by Loon Lake Dam, completed in 1963 as part of the Upper American River Project by Sacramento Municipal Utility District to conserve spring snow melt runoff for use during the summer and autumn for hydroelectric power production. Loon Lake Dam impounds water at the headwaters of Gerle Creek which, prior to the dam, flowed intermittently through (natural) Loon and Pleasant Lakes. But most of the water now stored in Loon Lake arrives from Buck Island Reservoir in the adjacent Rubicon River watershed by way of the Buck-Loon Tunnel. Nearby is Loon Lake Chalet, a popular winter recreation destination. In summer, a boat ramp for water sports and camping are available, but the area is less popular than nearby Union Valley Reservoir and Rubicon Trail. It is also known as Loon Lake Reservoir. Boaters refer to the northeast portion of the reservoir as the Pleasant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hell Hole Reservoir
Hell Hole Reservoir is an artificial, crescent-shaped lake in the Sierra Nevada mountain range west of Lake Tahoe in California, United States. The lake is about long when at full capacity. The lake was created in 1966 with the completion of Lower Hell Hole Dam across the Rubicon River, which is a major tributary of the Middle Fork of the American River. Hell Hole is named for a deep canyon which is now under the waters of the lake. How the canyon came to be named Hell Hole is a combination of folklore and speculation. An early author, George Wharton James (1858–1923), visited the canyon in 1913. He attributed the name to an unidentified miner seeking riches during the Squaw Valley mining excitement of 1862. It was "a hell of hole to get out of," James wrote, but admitted his source for the place name was more speculative than the anonymous miner's chances for riches at Squaw Valley. James' guide for the 1913 camping expedition to Hell Hole was Bob Watson, a well-known c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
