Humboldt Cave
Humboldt Cave is an archeological site in Churchill County, Nevada. Thirty-one caches were excavated from the cave, but there is only one radiocarbon date of 1953±175 14C BP (~2000 years ago) from the cave, which suggests that Humboldt Cave may have only been a single cultural component. In other words, the caches from the cave may have only been deposited once and at the same time. Description Humboldt Cave is a dry cave which was first excavated by archeologists in 1936. The cave's environment preserved artifacts including fiber and skin garments, bags and mats. Other artifacts found in the cave have documented contact with cultures in what were in what is now Arizona and California. The cave was formed by vertical faulting in a cliff face, which was periodically flooded by Lake Lahontan. The flooding deposited tufa over the cave's surfaces, preserving them from erosion. The remains of the lake, now known as Humboldt Sink, are below the cave, away. The cave opening is about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lovelock, Nevada
Lovelock is the county seat of Pershing County, Nevada, United States, in which it is the only incorporated city. It is the namesake of a nearby medium-security men's prison and a Cold War-era gunnery range. Formerly a stop for settlers on their way to California and later a train depot, the town's economy remains based on farming, mining and increasingly on tourism. History The area in which the township of Lovelock was to be established first came to prominence as a midpoint on the Humboldt Trail to California. According to an 1849 description of what were then called the Big Meadows, "This marsh for three miles is certainly the liveliest place that one could witness in a lifetime. There is some two hundred and fifty wagons here all the time. Trains going out and others coming in and taking their places is the constant order of the day. Cattle and mules by the hundreds are surrounding us, in grass to their knees, all discoursing sweet music with the grinding of their jaws.” ...

Churchill County, Nevada
Churchill County is a county in the western U.S. state of Nevada. As of the 2020 census, the population was 25,516. Its county seat is Fallon. Named for Mexican–American War hero brevet Brigadier General Sylvester Churchill, the county was formed in 1861. Churchill County comprises the Fallon, NV Micropolitan Statistical Area. It is in northwestern Nevada. Churchill County is noteworthy in that it owns and operates the local telephone carrier, Churchill County Communications. History Churchill County was established in 1861, and was named for Fort Churchill (which is now in Lyon County), which was named for General Sylvester Churchill, a Mexican–American War hero who was Inspector General of the U.S. Army in 1861. Churchill County was not organized until 1864, and its first county seat was Bucklands (which is now in Lyon County). In 1864 the county seat was moved to La Plata; in 1868 it was moved to Stillwater; and in 1904 it was settled in its present position, Fallo ...

Lake Lahontan
Lake Lahontan was a large endorheic Pleistocene lake of modern northwestern Nevada that extended into northeastern California and southern Oregon. The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west. The lake was named by Clarence King during the Geological Exploration of the Fortieth Parallel. The name honors Louis-Armand de Lom d'Arce de Lahontan, Baron de Lahontan, a French soldier and explorer. History At its peak approximately 12,700 years ago (during a period known as the Sehoo Highstand), the lake had a surface area of over , with its largest component centered at the location of the present Carson Sink. The depth of the lake was about at present day Pyramid Lake, and at the Black Rock Desert. Lake Lahontan, during this most recent glacial period, would have been one of the largest lakes in North America. Climate change around the end of the Pleistocene epoch led to a gradual desiccation of anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufa
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. It should not be confused with hot spring (thermogene) travertine. Tufa, which is calcareous, should also not be confused with tuff, a porous volcanic rock with a similar etymology that is sometimes also called "tufa". Classification and features Modern and fossil tufa deposits abound with wetland plants; as such, many tufa deposits are characterised by their large macrobiological component, and are highly porous. Tufa forms either in fluvial channels or in lacustrine environments. Ford and Pedley (1996) provide a review of tufa systems worldwide. Fluvial deposits Deposits can be classified by their depositional environment (or otherwise by vegetation or petrographically). Pedle ...

Humboldt Sink
The Humboldt Sink is an intermittent dry lake bed, approximately 11 mi (18 km) long, and 4 mi (6 km) across, in northwestern Nevada in the United States. The body of water in the sink is known as Humboldt Lake. The sink and its surrounding area was a notorious and dreaded portion (called the Forty Mile Desert) of overland travel to California during the westward migrations of the mid-1800s, which were largely undertaken along the California Trail. Humboldt Sink is located between the West Humboldt Range (to the southeast) and the Trinity Range (to the northwest), on the border between Pershing and Churchill counties, approximately 50 mi (80 km) northeast of Reno. It is fed from the northeast by the 330 miles (530 km) long Humboldt River, the second longest river in the Great Basin of North America (after the Bear River). Interstate 80 passes along the northwest side of the sink. The sink has no natural outlet. A channel connecting it with the ...

Guano
Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canvasback
The canvasback (''Aythya valisineria'') is a species of diving duck, the largest found in North America. Taxonomy Scottish-American naturalist Alexander Wilson described the canvasback in 1814. The genus name is derived from Greek ''aithuia'', an unidentified seabird mentioned by authors, including Hesychius and Aristotle. The species name ''valisineria'' comes from the wild celery ''Vallisneria americana'', whose winter buds and rhizomes are the canvasback's preferred food during the nonbreeding period. The celery genus is itself named for seventeenth century Italian botanist Antonio Vallisneri. The duck's common name is based on early European inhabitants of North America's assertion that its back was a canvas-like color. In other languages it is just a ''white-backed duck''; for example in French, ''morillon à dos blanc'', or Spanish, ''pato lomo blanco''. In Mexico it is called ''pato coacoxtle''. Description It ranges from in length and weighs , with a wingspan of . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bighorn Sheep
The bighorn sheep (''Ovis canadensis'') is a species of sheep native to North America. It is named for its large horns. A pair of horns might weigh up to ; the sheep typically weigh up to . Recent genetic testing indicates three distinct subspecies of ''Ovis canadensis'', one of which is endangered: ''O. c. sierrae''. Sheep originally crossed to North America over the Bering Land Bridge from Siberia; the population in North America peaked in the millions, and the bighorn sheep entered into the mythology of Native Americans. By 1900, the population had crashed to several thousand, due to diseases introduced through European livestock and overhunting. Taxonomy and genetics ''Ovis canadensis'' is one of two species of mountain sheep in North America; the other species being ''O. dalli'', the Dall sheep. Wild sheep crossed the Bering land bridge from Siberia into Alaska during the Pleistocene (about 750,000 years ago) and subsequently spread through western North America as far s ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
