A canyon or gorge is a deep cleft between escarpments or cliffs resulting from the erosive activity of a river over geologic timescales. A canyon may refer to a rift between two peaks, such as those in ranges including the Rocky Mountains, the Alps. Usually a river or stream and erosion carve out such splits between mountains, examples of mountain-type canyons are Provo Canyon in Utah or Yosemite National Park in Californias Sierra Nevada. Canyons within mountains, or gorges that have an opening on one side are called box canyons. Slot canyons are very narrow canyons, often with smooth walls, steep-sided valleys in the seabed of the continental slope underwater are referred to as submarine canyons. Unlike canyons on land, submarine canyons are thought to be formed by turbidity currents, the word canyon is Spanish in origin, with the same meaning. The word canyon is used in North America while the words gorge and ravine are used in Europe and Oceania, though gorge. In the United States, place names generally use canyon in the southwest and gorge in the northeast, in Canada, a gorge is usually narrow while a ravine is more open and often wooded.
The military-derived word defile is occasionally used in the United Kingdom, most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion, Canyons are much more common in arid than in wet areas because physical weathering has a more localized effect in arid zones. The wind and water from the combine to erode and cut away less resistant materials such as shales. The freezing and expansion of water serves to help form canyons, water seeps into cracks between the rocks and freezes, pushing the rocks apart and eventually causing large chunks to break off the canyon walls, in a process known as frost wedging. Canyon walls are formed of resistant sandstones or granite. Sometimes large rivers run through canyons as the result of geological uplift. These are called entrenched rivers, because they are unable to alter their course. In the United States, the Colorado River in the Southwest, Canyons often form in areas of limestone rock.
As limestone is soluble to an extent, cave systems form in the rock. When these collapse, a canyon is left, as in the Mendip Hills in Somerset and Yorkshire Dales in Yorkshire, England
The golden eagle is one of the best-known birds of prey in the Northern Hemisphere. It is the most widely distributed species of eagle, like all eagles, it belongs to the family Accipitridae. These birds are brown, with lighter golden-brown plumage on their napes. Immature eagles of this typically have white on the tail. Golden eagles use their agility and speed combined with powerful feet and massive, Golden eagles maintain home ranges or territories that may be as large as 200 km2. They build large nests in high places to which they may return for several breeding years, most breeding activities take place in the spring, they are monogamous and may remain together for several years or possibly for life. Females lay up to four eggs, and incubate them for six weeks, one or two young survive to fledge in about three months. These juvenile golden eagles usually attain full independence in the fall, once widespread across the Holarctic, it has disappeared from many areas which are now more heavily populated by humans.
It is the largest and least populous of the five species of true accipitrid to occur as a species in both the Palearctic and the Nearctic. Due to its prowess, the golden eagle is regarded with great mystic reverence in some ancient. The golden eagle is one of the most extensively studied species of raptor in the world in some parts of its range, such as the Western United States and the Western Palearctic. The golden eagle is a large, dark brown raptor with broad wings, ranging from 66 to 102 cm in length. This species wingspan is the fifth largest amongst extant eagle species, in the largest race males and females weigh typically 4.05 kg and 6.35 kg. In the smallest subspecies, A. c. japonica, males weigh 2.5 kg, in the species overall, males may average around 3.6 kg and females around 5.1 kg. The maximum size of species is a matter of some debate. Large races are the heaviest representatives of the Aquila genus and this species is on average the seventh-heaviest living eagle species, the golden eagle ranks as the second heaviest breeding eagle in North America and Africa but the fourth heaviest in Asia.
For some time, the largest known mass authenticated for a female was the specimen from the nominate race which weighed around 6.7 kg. No comprehensive range of weights are known for the largest subspecies, captive birds have been measured up to a wingspan of 2.81 m and a mass of 12.1 kg, respectively
Pinnacles National Park
Pinnacles is managed by the National Park Service and the majority of the park is protected as wilderness. The national park is divided by the formations into East and West Divisions, connected by foot trails. The east side has shade and water, the west has high walls, the rock formations provide for spectacular pinnacles that attract rock climbers. The park features unusual talus caves that house at least thirteen species of bat, Pinnacles is most often visited in spring or fall because of the intense heat during the summer months. Park lands are prime habitat for prairie falcons, and are a site for California condors that have been hatched in captivity. Pinnacles National Monument was established in 1908 by U. S. President Theodore Roosevelt, Pinnacles National Park was created from the former Pinnacles National Monument by legislation passed by Congress in late 2012 and signed into law by President Barack Obama on January 10,2013. Native Americans in the Pinnacles region comprised the Chalon and Mutsun groups of the Ohlone people and these native people declined with the arrival of the Spanish in the 18th century, who brought novel diseases and changes to the natives way of life.
The last Chalon had died or departed from the area by 1810, from 1810 to 1865, when the first Anglo-American settlers arrived, the Pinnacles region was a wilderness without human use or habitation. The establishment of a Spanish mission at Soledad hastened the areas native depopulation through disease, archaeological surveys have found thirteen sites inhabited by Native Americans, twelve of which post-date the establishment of the missions. One site is believed to be about 2000 years old, by the 1880s the Pinnacles, known as the Palisades, were visited by picnickers from the surrounding communities who would explore the caves and camp. The first account of the Pinnacles region appeared in print in 1881, between 1889 and 1891, newspaper articles shifted from describing excursions to the Palisades to calling them the Pinnacles. Interest in the rose to the point that the Hollister Free Lance sent a reporter to the Pinnacles. Investors came from San Francisco to consider placing a hotel there. In 1894 a post office was established in Bear Valley, since there was at least one other Bear Valley in California, the post office was named Cook after Mrs.
Hains maiden name. In 1924 the post office was renamed Pinnacles, Schuyler Hain was a homesteader who arrived in the Pinnacles area in 1891 from Michigan, following his parents and eight siblings to Bear Valley. White, was a student at Stanford University, and White brought one of his professors to see the Pinnacles in 1893, dr. Gilbert was impressed by the scenery, and his comments inspired Hain to publicize the region. Hain led tours to Bear Valley and through the caves, advocating the preservation of the Pinnacles, Hains efforts resulted in a 1904 visit by Stanford president David Starr Jordan, who contacted Fresno Congressman James C. Jordan and Needham in turn influenced Gifford Pinchot to advocate the establishment of the Pinnacles Forest Reserve to President Theodore Roosevelt, Roosevelt proclaimed the establishment on July 8,1906
Sequoia National Park
Sequoia National Park is a national park in the southern Sierra Nevada east of Visalia, California, in the United States. It was established on September 25,1890, the park is south of and contiguous with Kings Canyon National Park, the two are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. They were designated the UNESCO Sequoia-Kings Canyon Biosphere Reserve in 1976, the park is famous for its giant sequoia trees, including the General Sherman tree, the largest tree on Earth. The General Sherman tree grows in the Giant Forest, which five out of the ten largest trees in the world. The Giant Forest is connected by the Generals Highway to Kings Canyon National Parks General Grant Grove, the parks giant sequoia forests are part of 202,430 acres of old-growth forests shared by Sequoia and Kings Canyon National Parks. Indeed, the preserve a landscape that still resembles the southern Sierra Nevada before Euro-American settlement. Many park visitors enter Sequoia National Park through its entrance near the town of Three Rivers at Ash Mountain at 1,700 ft elevation.
The last California grizzly was killed in this park in 1922, the California Black Oak is a key transition species between the chaparral and higher elevation conifer forest. At higher elevations in the front country, between 5,500 and 9,000 feet in elevation, the landscape becomes montane forest-dominated coniferous belt, found here are Ponderosa, Jeffrey and lodgepole pine trees, as well as abundant white and red fir. Found here too are the giant sequoia trees, the most massive living single-stem trees on earth, between the trees and summer snowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see deer, Douglas squirrels, and American black bears. There are plans to reintroduce the bighorn sheep to this park, the vast majority of the park is roadless wilderness, no road crosses the Sierra Nevada within the parks boundaries. 84 percent of Sequoia and Kings Canyon National Parks is designated wilderness and is only by foot or by horseback. Sequoias backcountry offers a vast expanse of high-alpine wonders, covering the highest-elevation region of the High Sierra, the backcountry includes Mount Whitney on the eastern border of the park, accessible from the Giant Forest via the High Sierra Trail.
On the floor of canyon, at least two days hike from the nearest road, is the Kern Canyon hot spring, a popular resting point for weary backpackers. From the floor of Kern Canyon, the trail ascends again over 8,000 ft to the summit of Mount Whitney, in the summertime, Native Americans would travel over the high mountain passes to trade with tribes to the East. By the time the first European settlers arrived in the area, smallpox had spread to the region. The first European settler to homestead in the area was Hale Tharp, Tharp allowed his cattle to graze the meadow, but at the same time had a respect for the grandeur of the forest and led early battles against logging in the area
The coyote is a canid native to North America. It is smaller than its relative, the gray wolf, and slightly smaller than its other close relatives, the eastern wolf. It fills much of the ecological niche as the golden jackal does in Eurasia, though it is larger. The species is versatile and able to adapt to environments modified by humans, as human activity has altered the landscape, the coyotes range has expanded. In 2013, coyotes were sighted in eastern Panama for the first time, the coyote is more closely related to the common ancestor of wolves and other canids than the gray wolf. As of 2005,19 coyote subspecies are recognized, the average male coyote weighs 8 to 20 kg and the average female 7 to 18 kg. Their fur color is light gray and red or fulvous interspersed with black and white. It is highly flexible in organization, living either in a family unit or in loosely knit packs of unrelated individuals. The coyotes characteristic vocalization is a made by solitary individuals. Humans aside and gray wolves are the only serious enemies.
Nevertheless, coyotes do sometimes mate with gray, eastern, or red wolves, Most recent studies show that most wolves contain some level of coyote DNA. As with other figures, the coyote uses deception and humor to rebel against social conventions. The animal was especially respected in Mesoamerican cosmology as a symbol of military might, after the European colonization of the Americas, it was reviled in Anglo-American culture as a cowardly and untrustworthy animal. Unlike wolves, which have undergone an improvement of their public image, Coyote males average 8 to 20 kg in weight, while females average 7 to 18 kg, though size varies geographically. Northern subspecies, which average 18 kg, tend to larger than the southern subspecies of Mexico. Body length ranges on average from 1.0 to 1.35 m, the largest coyote on record was a male killed near Afton, Wyoming, on November 19,1937, which measured 1.5 m from nose to tail, and weighed 34 kg. Scent glands are located at the side of the base of the tail and are a bluish-black color.
The color and texture of the fur varies somewhat geographically
Lassen Volcanic National Park
Lassen Volcanic National Park is a United States National Park in northeastern California. The dominant feature of the park is Lassen Peak, the largest plug dome volcano in the world, Lassen Volcanic National Park started as two separate national monuments designated by President Theodore Roosevelt in 1907, Cinder Cone National Monument and Lassen Peak National Monument. The source of heat for volcanism in the Lassen area is subduction off the Northern California coast of the Gorda Plate diving below the North American Plate, the area surrounding Lassen Peak is still active with boiling mud pots, stinking fumaroles, and churning hot springs. Lassen Volcanic National Park is one of the few areas in the world where all four types of volcano can be found, the park is accessible via State Routes SR89 and SR44. SR89 passes north-south through the park, beginning at SR36 to the south, SR89 passes immediately adjacent the base of Lassen Peak. A large lodge with concession facilities was located near the south-west entrance, a new, full-service visitor center was constructed in the same location, and opened to the public in 2008.
Near the old location was located Lassen Ski Area. Native Americans have inhabited the area long before white settlers first saw Lassen. The natives knew that the peak was full of fire and water, White immigrants in the mid-19th century used Lassen Peak as a landmark on their trek to the fertile Sacramento Valley. One of the guides to these immigrants was a Danish blacksmith named Peter Lassen, Lassen Peak was named after him. Nobles Emigrant Trail was cut through the area and passed Cinder Cone. Inconsistent newspaper accounts reported by witnesses from 1850 to 1851 described seeing fire thrown to a terrible height, as late as 1859, a witness reported seeing fire in the sky from a distance, attributing it to an eruption. Early geologists and volcanologists who studied the Cinder Cone concluded the last eruption occurred between 1675 and 1700, after the 1980 eruption of Mount St. Helens, the United States Geological Survey began reassessing the potential risk of other active volcanic areas in the Cascade Range.
Further study of Cinder Cone estimated the last eruption occurred between 1630 and 1670, recent tree-ring analysis has placed the date at 1666. The Lassen area was first protected by being designated as the Lassen Peak Forest Preserve, Lassen Peak and Cinder Cone were declared as U. S. National Monuments in May 1907 by President Theodore Roosevelt. Starting in May 1914 and lasting until 1921, a series of minor to major eruptions occurred on Lassen and these events created a new crater, and released lava and a great deal of ash. Fortunately, because of warnings, no one was killed, because of the eruptive activity, which continued through 1917, and the areas stark volcanic beauty, Lassen Peak, Cinder Cone and the area surrounding were declared a National Park on August 9,1916. The 29-mile Main Park Road was constructed between 1925 and 1931, just 10 years after Lassen Peak erupted, near Lassen Peak the road reaches 8,512 feet, making it the highest road in the Cascade Mountains
National Park Service
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS.
On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States.
In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service
The Mojave Desert is an arid rain-shadow desert and the driest desert in North America. It is located in the southwestern United States, primarily within southeastern California and southern Nevada, very small areas extend into Utah and Arizona. The central part of the desert is sparsely populated, while its peripheries support large communities such as Las Vegas, Palmdale, the Mojave Desert is bordered by the Great Basin Desert to its north and the Sonoran Desert to its south and east. Topographical boundaries include the Tehachapi Mountains to the west, and the San Gabriel Mountains, the mountain boundaries are distinct because they are outlined by the two largest faults in California – the San Andreas and Garlock faults. The Mojave Desert displays typical basin and range topography and it occupies less than 50,000 sq mi, making it the smallest of the North American deserts. The Mojave Desert is often referred to as the desert, in contrast to the low desert. However, the Mojave Desert is generally lower than the Great Basin Desert to the north, the spelling Mojave originates from the Spanish language while the spelling Mohave comes from modern English.
The Mojave Desert receives less than 13 in of rain a year and is generally between 2,000 and 5,000 feet in elevation, zion National Park in Utah lies at the junction of the Mojave, the Great Basin Desert, and the Colorado Plateau. Despite its aridity, the Mojave has long been a center of production, fed by irrigation coming from groundwater. The Mojave is a desert of temperature extremes and two distinct seasons, winter months bring comfortable daytime temperatures, which dip precipitously to around 20 °F on valley floors, and below 0 °F at higher elevations. Storms moving from the Pacific Northwest can bring rain and in places even snow. More often, the shadow created by the Sierra Nevada as well as mountain ranges within the desert such as the Spring Mountains, bring only clouds. By early June, it is rare for another Pacific storm to have a significant impact on the regions weather, summer weather is dominated by heat. Temperatures on valley floors can soar above 120 °F and above 130 °F at the lowest elevations, low humidity, high temperatures, and low pressure, draw in moisture from the Gulf of Mexico creating thunderstorms across the desert southwest known as the North American monsoon.
Autumn is generally pleasant, with one to two Pacific storm systems creating regional rain events, october is one of the driest and sunniest months in the Mojave, and temperatures usually remain between 70 °F and 90 °F on the valley floors. After temperature, wind is the most significant weather phenomenon in the Mojave, during the June Gloom, cooler air can be pushed out into the desert from Southern California. In Santa Ana wind events, hot air from the desert blows out into the Los Angeles basin, wind farms in these areas generate power from these winds. The other major factor in the region is elevation
The greater roadrunner is a long-legged bird in the cuckoo family, from Southwestern United States and Mexico. The Latin name means Californian earth-cuckoo, along with the lesser roadrunner, it is one of two species in the roadrunner genus Geococcyx. This roadrunner is known as the cock, ground cuckoo. The roadrunner is about 52–62 cm long, has a 43–61 cm wingspan and it stands around 25–30 cm tall and is the largest cuckoo of the Americas. Roadrunners have 4 toes on each foot, two face forward, and two face backward. The toes are brown in color and have pale gold spots, the upper body is mostly brown with black streaks and sometimes pink spots. The neck and upper breast are white or pale brown with brown streaks. The breeding habitat is desert and shrubby country in the southwestern United States, the greater roadrunner nests on a platform of sticks low in a cactus or a bush and lays 3–6 eggs, which hatch in 20 days. The chicks fledge in another 18 days, pairs may occasionally rear a second brood.
This bird walks around rapidly, running down prey and it feeds mainly on small animals including insects, tarantulas, mice, small birds and especially lizards and small snakes. Venomous serpents, including rattlesnakes, are readily consumed. It kills prey by holding the victim in its bill and slamming it repeatedly against the ground, although capable of limited flight, it spends most of its time on the ground, and can run at speeds of up to 20 mph. Cases where roadrunners have run as fast as 26 mph have been reported and this is the fastest running speed clocked for a flying bird, but not nearly as fast as the 43 mph of the flightless and much larger ostrich. Some Pueblo Native American tribes, including the Hopi, believed the roadrunner provided protection against evil spirits, in Mexico, some said it brought babies, as the white stork was said to in Europe. Some Anglo frontier people believed roadrunners led lost people to trails, the roadrunner appeared in a 1982 sheet of 20-cent United States stamps showing 50 state birds and flowers, being the state bird of New Mexico.

A spring is any natural situation where water flows from an aquifer to the Earths surface. It is a component of the hydrosphere, a spring may be the result of karst topography where surface water has infiltrated the Earths surface, becoming part of the area groundwater. The groundwater travels through a network of cracks and fissure—openings ranging from intergranular spaces to large caves, the water eventually emerges from below the surface, in the form of a karst spring. The forcing of the spring to the surface can be the result of an aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources are artesian wells and this is possible even if the outlet is in the form of a 300-foot-deep cave. In this case the cave is used like a hose by the higher elevated area of groundwater to exit through the lower elevation opening. Non-artesian springs may simply flow from a higher elevation through the earth to a lower elevation, still other springs are the result of pressure from an underground source in the earth, in the form of volcanic activity.
The result can be water at elevated temperature such as a hot spring, the action of the groundwater continually dissolves permeable bedrock such as limestone and dolomite, creating vast cave systems. The term seep refers to springs with small flow rates in which the water has filtered through permeable earth. Fracture springs, discharge from faults, joints, or fissures in the earth, tubular springs, in which the water flows from underground caverns. Spring discharge, or resurgence, is determined by the springs recharge basin, factors that affect the recharge include the size of the area in which groundwater is captured, the amount of precipitation, the size of capture points, and the size of the spring outlet. Water may leak into the system from many sources including permeable earth, sinkholes. In some cases entire creeks seemingly disappear as the water sinks into the ground via the stream bed, grand Gulf State Park in Missouri is an example of an entire creek vanishing into the groundwater system.
The water emerges 9 miles away, forming some of the discharge of Mammoth Spring in Arkansas, human activity may affect a springs discharge--withdrawal of groundwater reduces the water pressure in an aquifer, decreasing the volume of flow. Springs are often classified by the volume of the water they discharge, the largest springs are called first-magnitude, defined as springs that discharge water at a rate of at least 2800 liters or 100 cubic feet of water per second. The scale for spring flow is as follows, Minerals become dissolved in the water as it moves through the underground rocks and this may give the water flavor and even carbon dioxide bubbles, depending on the nature of the geology through which it passes. This is why spring water is bottled and sold as mineral water. Springs that contain significant amounts of minerals are sometimes called mineral springs, Springs that contain large amounts of dissolved sodium salts, mostly sodium carbonate, are called soda springs
Rattlesnakes are a group of venomous snakes of the genera Crotalus and Sistrurus of the subfamily Crotalinae. The 36 known species of rattlesnakes have between 65 and 70 subspecies, all native to the America, ranging from southern Alberta, Rattlesnakes are predators that live in a wide array of habitats, hunting small animals such as birds and rodents. The threat of envenomation, advertised by the shaking of the titular noisemaker at the end of their tails. However, rattlesnakes fall prey to hawks, king snakes, Rattlesnakes are heavily preyed upon as neonates, while they are still weak and mentally immature. Large numbers of rattlesnakes are killed by humans, Rattlesnake populations in many areas are severely threatened by habitat destruction and extermination campaigns. Rattlesnake are the leading contributor to snakebite injuries in North America, rattlesnakes rarely bite unless provoked or threatened, if treated promptly the bites are seldom fatal. Rattlesnakes receive their name from the rattle located at the end of their tails, the scientific name Crotalus is derived from the Greek κρόταλον, meaning castanet.
The name Sistrurus is the Latinized form of the Greek word for tail rattler and shares its root with the ancient Egyptian musical instrument the sistrum, Rattlesnakes are native to the Americas, living in diverse habitats from southwestern Canada to central Argentina. The large majority of live in the American Southwest and Mexico. Four species may be found east of the Mississippi River, in the United States, the states with the most types of rattlesnakes are Texas and Arizona. Most species live near open, rocky areas, rocks offer them cover from predators, plentiful prey, and open basking areas. However, rattlesnakes can be found in a variety of other habitats including prairies, deserts. The most probable ancestral area of rattlesnakes is the Sierra Madre Occidental region in Mexico, the most probable vegetation or habitat of the ancestral area appears to be pine-oak forests. Feeding habits play an important ecological role by limiting the size of rodent populations, Rattlesnakes consume mice, small birds, and other small animals.
They lie in wait for their prey, or hunt for it in holes, the prey is killed quickly with a venomous bite as opposed to constriction. If the bitten prey moves away before dying, the rattlesnake can follow it by its scent, when it locates the fallen prey, it checks for signs of life by prodding with its snout, flicking its tongue, and using its sense of smell. Once the prey has become incapacitated, the rattlesnake locates its head by odors emitted from the mouth, the prey is ingested head-first, which allows wings and limbs to fold at the joints in a manner which minimizes the girth of the meal. The gastric fluids of rattlesnakes are extremely powerful, allowing for the digestion of flesh, optimal digestion occurs when the snake maintains a body temperature between 80 and 85 °F
Castle Dome (butte)
Castle Dome, or Castle Dome Peak is a prominent butte and high point of the Castle Dome Mountains northeast of Yuma, Arizona, in the northwestern Sonoran Desert. The butte lies approximately 22 miles east of the historical Castle Dome Landing of the Colorado River and it is located above and east of US Route 95 and the Castle Dome mining district. Castle Dome is noteworthy for its use for day hiking. It is coated in winter or spring snowstorms as a white landform. Castle Domes height is 3,788 feet, some noteworthy minerals from the Castle Dome Mountains region are vanadinite, wulfenite and fluorite. Some of the trails are, King Valley Road, McPherson Pass Trail, Big Eye Wash Trail, Castle Dome Mountains.
