Tag: Nevada

Nevada, often referred to as the “Silver State,” is located in the western United States. Renowned for its vast deserts and striking mountain ranges, the state boasts a diverse landscape that includes the arid Mojave Desert in the south and the forested Sierra Nevada mountains in the west. The state is famously home to Las Vegas, a vibrant city known for its bustling casinos, entertainment venues, and nightlife. Beyond the glitz of Las Vegas, Nevada offers rich history in its ghost towns, a legacy of the 19th-century mining boom. The state also features significant natural attractions, such as Lake Tahoe and Great Basin National Park, offering a wide range of outdoor activities. Nevada’s economy is driven by tourism, mining, and, increasingly, technology, making it a dynamic state with a blend of natural beauty and modern attractions.

Painted Lady Butterfly (Vanessa cardui)

Posted on by

The Painted Lady Butterfly (Vanessa cardui) is one of the most widespread and fascinating species of butterfly, often called the “cosmopolitan” butterfly due to its exceptional global distribution.

Painted Lady Butterfly (Vanessa cardui)
Painted Lady Butterfly (Vanessa cardui)

Scientific Taxonomy

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Nymphalidae (brush-footed butterflies)
  • Genus: Vanessa
  • Species: cardui (Linnaeus, 1758)

It belongs to the tribe Nymphalini within the subfamily Nymphalinae.

Description

The adult Painted Lady is a medium-sized butterfly with a wingspan of approximately 2–3.5 inches (5–9 cm), typically around 5.1–7.3 cm from wing tip to wing tip.

The upperside of the wings is predominantly orange-brown to pinkish-orange, with darker bases. The forewings feature a prominent black apical (tip) area adorned with prominent white spots and a white subapical bar along the leading edge. The hindwings display a submarginal row of five small black spots, sometimes with blue scales. The wing edges are distinctly scalloped.

The underside is more subdued and mottled with patterns of black, brown, gray, and some red-orange, featuring four small submarginal eyespots on the hindwing (a key distinguishing feature from similar species like the American Lady, Vanessa virginiensis, which has two larger eyespots).

Larvae (caterpillars) are grayish-brown with darker ends, a yellow dorsal stripe, and branched spines along the back and sides. Eggs are pale green with vertical ribs.

Behavior

Painted Ladies are highly migratory and fast-flying, capable of speeds up to 25–30 mph (40–50 km/h). They are strong, directional fliers that often use favorable winds.

Males defend territories against other males. In warmer climates, mating can occur year-round, though it ceases during colder periods. Adults are avid nectar feeders, visiting a wide variety of flowers (especially taller perennials), while larvae are polyphagous herbivores feeding on over 100 plant species, with favorites including thistles (Cirsium and Carduus), mallows, and other composites.

Their most remarkable behavior is long-distance migration, which is multi-generational (no single individual completes the full round trip). In North America, they overwinter in warmer southern regions (such as Mexico or the southwestern U.S. deserts) and move northward in spring, often triggered by rainfall and host plant availability, reaching as far as Canada and occasionally Alaska. In Europe and Africa, they undertake even longer journeys, including a documented 9,000-mile (≈14,500 km) round trip from tropical Africa to northern Europe (near the Arctic Circle) and back, spanning up to six generations. Southward return migrations often occur at high altitudes (over 500 meters), making them less visible. Migration appears driven primarily by environmental cues (e.g., weather, resource availability) rather than strict genetics.

Range

Vanessa cardui is the most widely distributed butterfly species in the world, found on every continent except Antarctica and Australia (though a related species, the Australian Painted Lady, V. kershawi, occurs there).

Its range spans:

  • North America (from subarctic Canada and southeastern Alaska south through the continental U.S. and Mexico)
  • Central America
  • Europe
  • Asia
  • Africa
  • Various oceanic islands

It inhabits diverse open habitats including fields, meadows, prairies, gardens, deserts, and disturbed areas, up to elevations of around 3,900 meters in some regions. Populations fluctuate dramatically with outbreaks occurring in some years due to favorable conditions for breeding and migration.

This adaptable, highly mobile species exemplifies resilience in the face of varying climates and habitats.

Sagebrush Checkerspot (Chlosyne acastus)

Posted on by

The Sagebrush Checkerspot (Chlosyne acastus) is a medium-sized butterfly belonging to the brush-footed family, well-adapted to arid environments in western North America.

Sagebrush Checkerspot (Chlosyne acastus)
Sagebrush Checkerspot (Chlosyne acastus)

Scientific Taxonomy

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Nymphalidae
  • Subfamily: Nymphalinae
  • Genus: Chlosyne
  • Species: Chlosyne acastus (W.H. Edwards, 1874)

Several subspecies are recognized, such as C. a. neumoegeni in parts of the southwestern range. The species is sometimes referred to as the Acastus Checkerspot in certain sources.

Description

The Sagebrush Checkerspot has a wingspan of approximately 1.5–2 inches (3.9–5.1 cm), with forewing lengths around 1.8–2.4 cm in some populations.

The upperside features a distinctive checkered pattern of black, orange-brown, and orange (paler in males, often brighter in females). The wings show black lines, smudges, and checks separating bands of pale to yellow-orange; the hindwing base may appear darker (sometimes largely black with limited orange in males). Postmedian bands can show red-orange tones in some individuals.

The underside is more contrasting, with the hindwing displaying bands of chalk-white (or pearly white spots) and brick red, outlined by black veins and edges. This ventral pattern, with more extensive white compared to similar species, aids identification.

It resembles other checkerspots (e.g., Northern Checkerspot or Rockslide Checkerspot) but is distinguished by habitat preference, lighter ventral banding, and specific wing markings.

(Images: Examples of Sagebrush Checkerspot upperside and underside views from various western U.S. locations.)

Behavior

Adults feed primarily on flower nectar from various plants in their arid habitats. Males perch in strategic locations (such as gulches or along washes) and sometimes actively patrol these areas to locate and court females. Flight is typically rapid and direct when disturbed, typical of many checkerspot species.

The flight period varies by region but generally occurs in spring to early summer (e.g., late April to late June in parts of the range like Oregon). Larvae feed on host plants in the Asteraceae family, including species such as green rabbitbrush (Chrysothamnus viscidiflorus), gray rabbitbrush (Ericameria nauseosa), desert yellow fleabane (Erigeron linearis), Mojave aster, and various asters in the genus Dieteria. The species is univoltine (one generation per year) in most areas, with adults timed to coincide with host plant and nectar availability.

Range and Habitat

The Sagebrush Checkerspot occurs across the western United States, from eastern North Dakota westward to eastern Washington, and southward to New Mexico, southern Arizona, and eastern California. It is found in states including Montana, Idaho, Oregon, Wyoming, Nevada, Utah, Colorado, and parts of the Great Basin and Southwest. Populations extend into shrub-steppe regions of southern British Columbia in some accounts, though primarily a U.S. species.

It inhabits dry, arid lowlands, typically below 5,000 feet in many areas (e.g., below 3,000 feet in parts of the Columbia and Snake River basins). Preferred habitats include sagebrush scrub, pinyon-juniper woodlands, dry gulches, washes, canyons, brushy flats, sage deserts, and hilly short-grass prairies. It thrives in shrub-steppe and semi-arid environments dominated by sagebrush and associated plants.

Overall conservation status is secure (G5 globally in many assessments), though local populations may face threats from habitat alteration in arid regions. It is not generally considered rare or imperiled across its broad range.

White-lined sphinx moth (Hyles lineata)

Posted on by

The white-lined sphinx moth (Hyles lineata), also commonly known as the hummingbird moth or hawk moth due to its rapid, hovering flight and nectar-feeding behavior, is a member of the family Sphingidae. It is one of the most widespread and abundant sphinx moths in the Americas.

Description of the Adult

Adult white-lined sphinx moths are large and robust, with a wingspan of 2.5–3.5 inches (6–9 cm). The forewings are predominantly dark olive-brown to gray-brown, featuring a prominent broad pale tan or white band running diagonally from the base to the tip, along with narrower white streaks along the veins (the source of the “white-lined” name). The hindwings are darker, often blackish with a bright pink or rose central band and black spots. The thorax is “furry” and robust, the abdomen conical and extending beyond the wings at rest, and the proboscis is long for reaching deep into flowers. They are strong fliers, often mistaken for hummingbirds, and are primarily crepuscular (active at dawn and dusk) but can be diurnal in some conditions.

Life Cycle Stages

Like all Lepidoptera, H. lineata undergoes complete metamorphosis with four distinct stages: egg, larva (caterpillar), pupa, and adult.

  • Egg: Females lay small, spherical, pale green to yellowish eggs singly or in small groups on the leaves or stems of host plants. Each female can produce hundreds of eggs. Incubation typically lasts about 1 week, depending on temperature.
  • Larva (Caterpillar): The caterpillars are highly variable in color and pattern (polymorphic), ranging from bright yellow-green to dark green, black, or yellowish forms, often with complex markings including black, yellow, orange, or red spots, lines, or stripes along the body. All forms feature a prominent flexible horn (caudal horn) at the rear end, typical of sphingid larvae. They grow up to 3–3.5 inches (7–9 cm) long through five instars, feeding voraciously on foliage. This stage lasts about 3–4 weeks. In high-density years, caterpillars can form mass migrations across landscapes after defoliating host plants.
  • Pupa: Mature larvae burrow 1–4 inches into the soil to form a shallow chamber and pupate. The pupa is shiny dark brown to reddish-brown, spindle-shaped, about 1.5–2 inches long, with a prominent cremaster (hook-like structure) at the rear for anchoring. The pupal stage lasts 2–3 weeks in summer or longer if overwintering (in cooler regions, pupae may diapause through winter). Emergence is triggered by temperature and moisture cues.
  • Adult: Adults emerge from the pupa, live 1–2 weeks, and focus on reproduction and nectaring. They are important pollinators of tubular flowers.

The species typically completes 2 generations per year in most of its range, with multiple generations in warmer southern areas and potentially one in cooler northern zones. In some regions, it is migratory, with populations moving northward in spring and sometimes failing to overwinter in colder areas.

Host Plants and Ecology

Larvae are extremely polyphagous, feeding on a wide variety of plants across families such as Onagraceae (e.g., evening primrose Oenothera spp.), Portulacaceae (purslane), Vitaceae (grape), Rosaceae (apple, rose), and many others including willowherb, four o’clock, elm, tomato, fuchsia, and more. Adults nectar from long-tubed flowers like honeysuckle, columbine, larkspur, salvia, and evening primrose.

Geographic Range and Habitat

Hyles lineata has one of the broadest distributions among North American sphinx moths, ranging from Central America (including parts of South America in some records) through Mexico, the entire contiguous United States, and into southern Canada. It is occasionally reported in the West Indies, and vagrants have appeared in Eurasia and Africa. It prefers open habitats such as deserts, fields, gardens, prairies, woodlands edges, suburbs, and disturbed areas, thriving in diverse climates from arid to temperate. In areas like Nevada (including Las Vegas vicinity), it is common, especially during irruption years when populations boom due to abundant wildflowers or host plants.

This species plays a key ecological role as a pollinator and herbivore, with occasional outbreaks benefiting certain cultural groups historically (e.g., as a food source). It is not considered a major pest in most contexts, though larvae can defoliate garden plants during population spikes.

Mazuma Nevada – Pershing County Ghost Town

Posted on by

Mazuma, Nevada, was a short-lived gold mining boomtown in the remote Seven Troughs mining district of Pershing County, in northwestern Nevada. Located at the mouth of Seven Troughs Canyon in the Seven Troughs Range, approximately 25-30 miles northwest of Lovelock and about 30 miles from the county seat, the town sat in a vulnerable position prone to flash flooding from the surrounding mountains.

Mazuma, Nevada - 1908
Mazuma, Nevada – 1908

The name “Mazuma” derives from Yiddish slang for “money” or “ready cash,” reflecting the optimistic spirit of the gold rush era.

Founding and Boom Period

The townsite was established in late 1906 by S.B. Hill and Starr Hill at the base of the canyon. It formed as part of the 1907 rush to the Seven Troughs district, alongside nearby camps like Seven Troughs, Vernon, and Farrell. Gold discoveries in the area, particularly at mines such as the Mazuma Hills Mine, drove rapid growth.

By mid-1908, Mazuma had become the most prosperous settlement in the district. Within just six weeks of its founding, it boasted:

  • A mercantile house (general store)
  • Three restaurants
  • A lodging house
  • Five saloons
  • Other businesses

The town later featured more substantial structures, including a two-story bank, a three-story hotel, stamp mills (for processing ore), a post office (established 1907), and homes for residents. Population estimates during its peak hovered around 80-100 people, typical of small mining camps in the region. It served as a key milling and support hub for nearby gold operations, with at least two stamp mills operating there.

The Tragic Flash Flood of 1912

Mazuma’s prosperity ended abruptly on July 18, 1912 (some sources note July 11 or 19 due to reporting variations; the event occurred around 5 p.m.). A sudden and intense cloudburst struck the Seven Troughs Range above the town. Heavy rain in the mountains funneled massive amounts of water down Burnt Canyon and Seven Troughs Canyon.

A towering wall of water—described as 20 feet high and 150 feet wide—rushed into Mazuma without warning. Attempts to telephone warnings from upstream failed or came too late. The flood devastated the town, destroying most buildings, sweeping away homes, businesses, and debris including mining equipment and even a bank vault reportedly carrying $20,000 in gold bullion (which was carried nearly two miles downstream).

The disaster claimed eight lives (some accounts suggest up to 11), nearly one-tenth of the population. Victims included children from the Kehoe family (three siblings) and others caught in the torrent. The Seven Troughs Cyanide Plant was also destroyed, releasing cyanide into the floodwaters and adding to the hazard.

Surviving structures were limited to the two-story hotel, the general store, a few cabins, and the Darby Mill (or similar remnants). The post office closed shortly after, in late 1912.

Yesterday afternoon, at about five o’clock, the town of Mazuma (northeast of Reno) was devastated, eight people were drowned and nine more injured, many fatally, and a property loss estimated at nearly $200,000 by a cloud burst that swept down, unheralded, upon the mountain town. The known dead are:

Edna Russell, Postmistress at Mazuma;

Three children of Wm. Kehoe, all aged under seven;

M.C. Whalen, a miner, aged 35;

Mrs. Floyd Foncannon, drowned in Burnt Canyon six miles north of Seven Troughs canyon.

Those injured so far as can be learned at time of going to press are:

John Trenchard, merchant, probably fatally;

Mrs. Trenchard, badly cut and bruised, may recover.

Mrs. Kehoe, cut about head and face, bruised about body, may die;

Mrs. O’Hanlan, badly injured, may recover.

——————

Today the first witnesses of the flood conductions and who talked to the survivors returned to town. Among them was Drs. Russell and West, H.J. Murriah, J.T. Goodlin, H.S. Riddle, Jack and Will Borland and W.H. Copper.

Aftermath and Legacy

Mazuma was never rebuilt. The flood marked the effective end of the town, accelerating the decline of the entire Seven Troughs district. Nearby Seven Troughs and Vernon also faded, with small-scale mining continuing sporadically into the 1950s but no major revival. A later tunnel project (Tunnel Camp) attempted to drain mines but ultimately failed.

Today, Mazuma is a classic Nevada ghost town. Scattered ruins, debris from the flood (such as old cans, pipes, and mining remnants), and a small cemetery remain visible in the desert landscape. The site has returned largely to nature, with little left beyond rubble as early as the 1950s. It attracts ghost town explorers and historians interested in the dramatic story of a community erased almost overnight by nature.

The tragedy of Mazuma stands as a stark reminder of the risks faced by early 20th-century mining camps in arid regions—boom driven by precious metals, bust delivered by sudden desert floods.

John Percival Jones

Posted on by

John Percival Jones (January 27, 1829 – November 27, 1912) was a prominent Anglo-American mining entrepreneur, capitalist, and long-serving politician whose career epitomized the intersection of Western mining booms, corporate investment, and national politics in the late 19th century. Known as one of the “Silver Senators,” Jones amassed significant wealth through silver mining in Nevada’s Comstock Lode before expanding his investments into California. His political influence as a U.S. Senator from Nevada for 30 years (1873–1903) amplified his role in promoting mining interests, free silver policies, and regional development.

Early Life and Arrival in the West

Born at “The Hay” in Herefordshire, England, Jones immigrated to the United States as an infant in 1829 with his family. He grew up in New York before heading west during the California Gold Rush. In 1849, at age 20, he arrived in California and settled in Trinity County in the northern part of the state. There, he engaged in placer mining, farming, and local affairs, serving as sheriff and justice of the peace in Weaverville. These early experiences in the Mother Lode region honed his skills in mining operations and frontier governance, though he did not achieve major wealth in California gold mining at this stage.

Rise in Nevada: The Comstock Lode and Crown Point Mine

Jones moved to Nevada in the mid-1860s amid the excitement of the Comstock Lode, the legendary silver discovery near Virginia City (then part of Utah Territory, later Nevada). In 1868, he became superintendent of the Crown Point Mine in Gold Hill, a key producer on the Comstock Lode. Under his management, the mine struck a rich ore body, propelling Jones to millionaire status and earning him the reputation as the Comstock’s first millionaire mine superintendent.

His heroism during a deadly 1869 fire on the Comstock further enhanced his stature. Jones was credited with brave actions that saved lives and property. This success, combined with his operational expertise, positioned him as a leading figure in Nevada’s mining industry. The Comstock’s deep, hardrock silver mining required substantial capital, corporate organization, and technological innovation—areas where Jones excelled as both manager and investor.

Political Career and the “Silver Senator” Era

In 1873, Jones was elected as a Republican U.S. Senator from the new state of Nevada, serving continuously until 1903—a remarkable 30-year tenure. He joined fellow mining magnate William Morris Stewart (another Comstock lawyer-turned-senator) in representing Nevada’s interests in Washington. Both became staunch advocates for free silver (bimetallism), opposing the gold standard and pushing policies favorable to Western mining states. Jones’s wealth and influence made him a powerful voice for silver producers nationwide.

Mining Investments in Nevada and California

Jones’s mining career extended beyond the Comstock. In Nevada, his Crown Point success provided the capital for further ventures. He invested in various Comstock properties and remained active as a capitalist even after entering the Senate.

Panamint City Stamp Mill
Panamint City Stamp Mill

His most notable California investment came in the mid-1870s with the Panamint silver district in the Panamint Range (now part of Death Valley National Park). In 1873–1874, rich silver outcrops were discovered in Surprise Canyon by prospectors (including former outlaws). Hearing of the excitement, Jones—fresh from Comstock riches—partnered with Senator Stewart to form the Panamint Mining Company. They invested heavily (reports vary from $250,000–$350,000 personally, plus millions raised from investors) to acquire controlling interests in key claims like the Wyoming and Wonder mines. They organized the district, built infrastructure (including a 20-stamp mill), and promoted the camp aggressively.

Panamint City boomed briefly to 1,500–2,000 residents in 1874–1875, becoming infamous for lawlessness (dozens of murders reported). Jones and Stewart floated stocks on the San Francisco Mining Exchange and cast bullion into heavy cubes to deter theft. However, the high-grade ore depleted quickly, and a devastating flash flood in 1876 destroyed much of the town. By 1877, operations collapsed amid a market panic, yielding little return despite massive investment. This bust highlighted the speculative risks of remote desert mining.

Jones also pursued broader California ventures tied to his mining interests. In 1874, he partnered with Colonel Robert S. Baker to develop Santa Monica as a seaside resort and potential port. He purchased a three-fourths interest in Baker’s Rancho Boca de Santa Monica ranch for $162,500 and built the Los Angeles and Independence Railroad (a narrow-gauge line from Los Angeles to Santa Monica, completed in 1875 without subsidies). Originally intended to connect to Inyo County silver mines (including Panamint) via Independence, financial strains from failing mines forced Jones to sell the railroad to Collis P. Huntington’s Southern Pacific in 1877. Santa Monica’s founding and early growth remain his most enduring California legacy.

Later Life and Legacy

After retiring from the Senate in 1903, Jones lived in comfort, dividing time between Washington, D.C., New York (where he owned a hotel), San Francisco (with a Turkish bath investment), and California properties. He pursued other interests, including early water reclamation ideas linked to what became Hoover Dam. He died in Santa Monica on November 27, 1912.

John P. Jones embodied the transition from individual prospecting to corporate mining capitalism in the American West. His Comstock fortune funded ambitious but often risky ventures like Panamint, while his Senate role shaped national mining and monetary policy. Though some investments (notably Panamint) ended in disappointment, his role in founding Santa Monica and promoting Western resource development left a lasting mark on California and Nevada history.
