13-Places & Structures: As I travel and hike around the state, I am always looking historic buildings that are indicative of the area. Many of the places where I hike even have visitor centers containing interpretative displays and gift shops. Sometimes, places such as the Hoover Dam or museums are a destination all by themselves.

Introduction: As I began to discover more and more rock art sites during my hikes over these past several years, I have become witness to far too many examples of where persons had seemed fit to deface them with graffiti and other examples of damage. Eventually I realized that the sharing of my hiking adventures could have the potential to increase public exposure, and thereby increasing the possibility for even more damage. As a result, I decided to preface each of my rock art pages with the following information to help educate visitors about the importance of these fragile cultural resources. Before scrolling down, I implore you to READ the following ... as well as the linked page providing guidelines for preserving rock art.

Here are a few simple guidelines you can follow that will help to preserve these unique and fragile cultural resources that are part of our heritage. Guidelines for Preserving Rock Art. If you would like to learn more about the Nevada Site Stewardship Program, go to my page ... Nevada Site Stewardship Program (NSSP)).

Guidelines For Preserving Rock Art
  • First and foremost, DO NOT Touch. Even a small amount of the oils from our hands can erode petroglyphs & pictographs and destroy the patina (color) of the carved, pecked or painter image. Any interaction with the surface may interfere with dating efforts.
  • DO NOT try to make rubbings or molds from petroglyphs. (Take a picture instead!)
  • DO NOT introduce any foreign substance to enhance the carved, pecked or painted images for photographic or drawing purposes.
  • When climbing among the rocks be careful, making sure that you do not dislodge loose stones that may cause damage to the petroglyph & pictograph boulders. Falling rocks may scratch the carved and pecked images causing unintentional damage.
  • NEVER re-arrange the rocks or move things from where you find them. The petroglyphs & pictographs are important individually and in relation to each other. To even try and understand a petroglyph or pictograph it needs to be viewed in relation to its environment: including the adjacent image(s), the entire basalt escarpment, and the surrounding landscape.
  • DO NOT add your own marks to the images. The introduction of graffiti destroys the petrographs & pictographs and is disrespectful to contemporary Native Americans and their ancestors.
  • Beware of vandalism or collection (stealing) of petroglyphs. It is against the law! Report violators to either local law enforcement agencies, BLM or a National Parks & Recreation office.
  • Behave in a manner of respect for the sacred or magical lands that the petroglphs adorn. Many of these places held special meanings for those that carved them. It may be that it was a holy place of worship for those early inhabitants. For all we know of some petroglyph sites, they may still be places used for outdoor worship.

By all means, hike out in the desert and enjoy these free galleries, but do so responsibly. Exercise extreme cautions when viewing and photographing petroglyphs. Whenever you stumble upon a treasure trove of artistic history, try to think of it as your own private viewing. Take the time to revel in its history. Try to place yourself there, perhaps a thousand years ago, leaving a message for some future generation.

Template - Terms Commonly Associated with Rock Art Study

If you're new to rock art and petroglyphs, you'll undoubtedly run across some terms that you're unfamiliar with. To refresh those who are already acquainted with rock art terminology and, to enlighten others who are not familiar with them.  Here are some of the basics: 1-references
~ A ~
Abraded -


abstract motif 



AMS 14C -


A method of making rock images by lightly rubbing the rock surface with a coarse, durable stone tool; a shallower effect than cupule
Any rock art image of a kind too abstruse, not easily understood, or so stylized as to be unrecognizable as a real object or living thing. A non-figurative motif not recognizable as an object of the real world.
Accelerator Mass Spectrometry, a method of radiocarbon dating (i.e., Carbon-14) which directly measures the amount of 14C in a sample; because

microscopic traces can be dated, AMS is used on rock imagery to date both organic binders in pictographs and microbial residues in rock varnish.
alluvial –
Of, pertaining to, or composed of sediment deposited by flowing water.
anthropic –
Pertaining to human form
anthropocentric –
Relating to imagery that predominantly depicts humanlike figures.
anthropology –
The study of humanity, attempting to establish what defines Homo sapiens, who our ancestors are, what out physical traits are, how we behave, why there are variations among different groups of humans, and how the evolutionary past of Homo sapiens has influenced its social organization and culture.
anthropomorph –
A term used in rock art studies to describe a motif with human attributes. Any rock art element of human-like form, stylized or realistic.
archaeology 
































Archaeological Sites - 
Archaeoastronomy - 

The scientific study of ancient cultures and their life and activities through the examination of their material remains such as fossil relics, artifacts, tools, and other artifacts usually dug up from the ground.

Archaeology The scientific study and reconstruction of the human past through the systematic recovery of the physical remains of man's life and cultures. Artifacts, structures, settlements, materials, and features of prehistoric or ancient peoples are surveyed and / or excavated to uncover history in times before written records. Archaeology also supplements the study of recorded history. From the end of the 18th century onwards, archaeology has come to mean the branch of learning which studies the material remains of man's past. Its scope is, therefore, enormous, ranging from the first stone tools made and fashioned by man over 3 million years ago in Africa, to the garbage thrown into our trash cans and taken to city dumps and incinerators yesterday. The objectives of archaeology are to construct cultural history by ordering and describing the events of the past, study cultural process to explain the meaning of those events and what underlies and conditions human behavior, and reconstruct past lifeways. Among the specialties in the field are: archaeobiology, archaeobotany, archaeozoology, and social archaeology. Modern archaeology, often considered a subdiscipline of anthropology, has become increasingly scientific and relies on a wide variety of experts such as biologists, geologists, physicists, sociologists, anthropologists, and historians. The methods appropriate to different periods vary, leading to specialized branches of the subject, e.g. classical, medieval, industrial, etc., archaeology.

The study of ancient cultures’ knowledge of, and use of
astronomy; such knowledge may be incorporated in rock imagery. Also known as “Astroarchaeology.”
archaic period
7,000 BC is known as the Archaic Period, a time in which people, known as hunter-gathers, built basic shelters and made stone weapons and stone tools. The early Desert Archaic peoples, like their Paleo-Indian predecessors, traveled in small mobile groups, probably extended families, in a ceaseless quest for food, materials, fuel and water. They carried their belonging on their backs, which prevented the accumulation of material wealth and, probably, the development of marked social status.

atlatl –




Attribute -




Azimuth - 






A weapon used for hunting that propelled darts or small spears. It was later replaced by the bow and arrow around 500 A.D. The Atlatl is often depicted as a circle with a line through it.

 Any meaningful characteristic about a rock art design, either natural or cultural such as an element, technique of manufacture, type of paint, panel orientation, landscape setting, degree of varnish, etc.

A direction relative to true north defined in one-degree increments,
increasing clockwise with 360° around the entire horizon; used to precisely define
the direction a rock art panel “faces.”
~ B ~
binder –
A component of rock art paint, assisting uniform consistency, solidification or adhesion.
biomorph
An object or picture providing adequate visual information to contemporary humans as resembling a biological form - human, animal, or plant..
~ C ~
cairn –
An anthropic mound of stones.
carbon dating –
Also known as the Carbon 14 method and radio-metric dating. A scientific technique for determining when organic remains such as charcoal, bone, shell, and plant material died. Organic matter contains radioactive carbon-14 isotopes, which decay over time at a known rate. Carbon dating measures the remaining volume of carbon-14 isotopes in matter, providing an approximate age since death. Although often pigments used in rock painting contained an organic binder such as blood, there is usually too little pigment remaining on the rock to make direct dating possible.
chert –
A collective term for sedimentary microcrystalline silica rock formed by selective replacement of limestone; in some regions occurring as flint.
chronology –
The arrangement of past events or manifestations according to their temporal sequence, and the science of providing dates for them.
clast
A fragment of rock of any size, but used especially to denote cobble-sized angular breakdown debris.; synonymous to detritus.
concretion –
A coalesced deposit of mineral matter formed through the deposition of a cementing mineral precipitate, such as carbonate, silica or iron salts.
cupule –
A cup shaped depression in the surface produced by grinding, pecking or a combination of both. They are also referred to as “pit-and-groove.” These cup-like depressions or pits in boulders are thought to be the oldest form of rock art, first appearing in parts of the Great Basin 7000 years ago.
curvilinear –
An element or motif consisting of curved lines.
~ D ~
desert varnish –
Desert varnish, also called Patina, is a thin, dark red to black mineral coating (generally iron and manganese oxides and silica) deposited on the surface of pebbles and rocks of desert regions. As dew and soil moisture brought to the surface by capillarity evaporate, their dissolved minerals are deposited on the surface. The rate of varnish formation varies: it generally is thought to take about 2,000 years for it to form in arid areas, because it coats artifacts and natural objects known to be of such antiquity; but it has formed in less than 50 years in the Mojave Desert. Both high evaporation rates and sufficient precipitation are necessary for desert varnish formation.
~ E ~
early Pleistocene –
The earliest geological period of the Quaternary, from about 1.8 million years ago to 780 000 years ago.
engravings –
Also known as petroglyphs. Engravings are pictures, patterns, or designs cut into rock faces by pecking, scraping or grinding with a tool.
elements
The individual markings that comprise portions or parts of a motif that make of a panel.
erosion
a natural process by which mineral or earth matter is removed, including dissolution, weathering, abrasion, corrosion or transportation.
~ F ~
figure –
A design or pattern painted, drawn, pressed or engraved on a rock surface; a rock art motif, sometimes referred to as representational rock art.

figurative –
Providing visual information recognized by contemporary humans as resembling the form of an object
~ G ~

gallery
A large concentration of rock art, not necessarily continuous, consisting of a number of panels.

geoglyph
Large ground figures produced either by building up rock alignments (such
as cairns) or scraping away rocks or desert pavement (intaglio).

geomorph
A rock art motif of simple geometrical form or design, such as circle, line, cupule, CLM, barred lines. Sometimes called a geometric motif.
glyph
Slang for a petroglyph motif; in archaeology, a symbol in a writing system

grinding slick
A flat or shallow surface formed by grinding or crushing of foods with a stone.

Great Basin  –
A desert region of the western United States comprising most of Nevada and parts of Utah, California, Idaho, Wyoming, and Oregon. Coined by John C. Frémont who explored and named the area (1843-1845). It comprises roughly 210,000 sq. mi.
~ H ~

hand print
A positive pigmented imprint of a human hand, made by pressing a paint-covered hand against the rock surface.
hand stencil –
A negative pigmented imprint of a human hand, made by spraying paint over the hand’s outline while it is pressed against the rock surface.
Holocene –

Varnish Microlamination (VML) –
Varnish microlamination (VML), as a correlative dating technique, is relatively new and different in principle and independent of both cation-ratio and AMS 14. Rock varnish is a dark coating on subaerially exposed rock surfaces. It is probably the world's slowest-accumulating sedimentary deposit, growing at only a few to tens of microns per a thousand years. As a unique dating technique, the VML method has great chronometric applications in earth science and geoarchaeology. it can yield minimum-limiting surface exposure ages for various geomorphic features (e.g., alluvial-fan surfaces, desert pavements, hillslope deposits, lava flows, debris flows, fault scarps, meteor crater) and geoarchaeological features (e.g., stone tools, petroglyphs, geoglyphs)
~ X ~

X-ray fluorescence(XRF) –
XRF is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
~ Z ~

zoomorph –
A figure that resembles an animal body.

Zoomorphic –
Pertaining to a zoomorph.
vandalism –
The defacing or destruction of rock art, or impairing of its scientific potential.

Template - Mining Terms

Mines are dug to follow an externally visible vein of ore into a formation such as a hill or mountain side. Piles of waste rock outside a mine containing no precious ores are called tailings.
                        
ADIT: An ADIT is a horizontal mine feature, usually dug into the side of a hill or mountain. The top (ceiling) of an adit is called the Back. The sides of an adit are called the Ribs. If an adit is open at both ends, it becomes a tunnel.
COLLAR: A COLLAR is the point of entry to a shaft. It most often has a wooden frame around it to keep the edges from caving in.
CONCENTRATION MILL:    Concentrators concentrate ore. Example; Ore of, say, half ounce of gold and twelve ounces of silver per ton might be concentrated to 2.5 ounces of gold and 60 ounces of silver per ton of concentrates - the value increased per ton, by a factor of five. This was done to save on freight costs.
CROSSCUT: Is a passageway that is used to connect drifts and stopes.
DRIFT: A near-horizontal secondary passageway that is connested to a shaft, or an adit. Drifts usually follow the ore vein.
GRIZZLY: A grating of iron or steel bars for screening ore.
HEADFRAME: A large wooden frame which supports the cable and bucket or cgae when hoisting ore. A structure over a mine shaft which holds a pulley for the steel cable that raises and lowers the skip in the mine shaft.
HOIST: An engine for raising ore and water from a mine and for lowering and raising men, material and machinery utilizing a drum and steel cable - usually connected to a Headframe.
JAW CRUSHER: A machine for reducing the size of materials by impact or crushing between a fixed plate and an oscillating plate, or between two oscillating plates, (forming a tapered jaw) before sending the ore through a stamp mill.
LODE: A fissure or vein in rock filled with minerals, a vein producing valuable metallic ore between definite boundaries, as in the Mother Lode.
MILLING: The process of dressing ore by crushing, stamping, amalgamation, leaching, etc. to separate the gold from the base rock.
MINE: The further development of a prospect that creates a more expansive shaft or adit into the earth for the excavation of valuable minerals or ubstances.
MUCK: The rock pile resulting from blasting. Miners shoveling the muck were muckers.
ORE SKIP: The cage, or basket, that carries the ore to the surface.
OVERBURDEN: The leftover ore from a strip mining operation.
PORTAL: The opening to an adit or tunnel is called a portal, which is sometimes framed with wooden timbers.
PROSPECT: The exploration of a property suspected of containing a potentially economic mineralization/deposit that may be worth the expense of additional mining. Usually a small, hand dug shaft or adit. A successful prospect is developed into a mine.
RAISE: A vertical, or inclined passageway, driven at an upward angle. A mine shaft driven upward from a level to connect with the level above, or to explore the ground for a limited distance above one level. After two levels are connected, the connection may be a winze or a raise, depending upon which level is taken as the point of reference.
SHAFT: A SHAFT is a vertical mine feature. Miners often dug directly down to follow the ore vein. The opening to a shaft is called the collar. A SUMP is a continuation of a shaft with the purpose of collecting water and preventing flooding by weather or ground seepage.
STAMP MILL: A stamp is a pestle that is raised by some form of power, typically water or steam. Gravity causes the stamp to drop, crushing ore placed between the stamp's shoe and the die. A common pattern in stamp mill design was to use five stamps in a battery. This set up used a tappet at the top and the stamp was lifted and dropped by the revolving cam engaging the underside of the tappet. A machine, and the building containing it, in which crushed rock is crushed even smaller by descending rods with stamp shoes, usually lifted and dropped by a cam, and operated by water power, steam power or later on by electric motor. Usually arranged in groups of five, each stamp weighed up to 2000 pounds and dropped 6 to 8 inches. Each stamp battery dropped up to 100 times per minute, and could be heard for miles. Amalgamation was usually combined with the crushing when gold or silver ore was processed.
STOPE: The portion of the mine being currently worked. They can follow a vein in every direction, from narrow passageways to huge caverns; any excavation in a mine, other than development workings, made for the purpose of extracting ore. The outlines of the ore body determine the outlines of the stope. If an adit or drift is successful in following a vein to a large ore body, a STOPE will be made by removing all the available ore. The result can resemble a cavern. Larger stopes are often referred to as ballrooms.  A stope that breaches the surface becomes an OPEN STOPE.
STRIP MINING: Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden). "Contour stripping" involves removing the overburden above the mineral seam near the outcrop in hilly terrain, where the mineral outcrop usually follows the contour of the land. Contour stripping is often followed by auger mining into the hillside, to remove more of the mineral. This method commonly leaves behind terraces in mountainsides.
SURFACE MINING: Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. It is the opposite of underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels.
TAILINGS: The waste material left after ore has been crushed and the desired mineral removed. At first dumped near the mine entrance, after 1914 the Kennedy Mine used large tailing wheels to move the mine tailings to an impound dam away from the mill site.
WHIM: A method of hoisting ore using a horse, and usually two men, pulling a wire rope over a pulley and down into the shaft. This method is a more robust hoisting method than whip method.
WHIP: A method of hoisting ore using a horse, or man, pulling a rope that went over a pulley and down into the shaft.
WINZE: A winze is a shaft dug within an adit or drift to explore the lower levels of ground beneath the original vein. A vertical, or inclined passageway, driven at a downward angle. A vertical opening driven downward connecting two levels in a mine. When one is standing at the top of a completed connection the opening is referred to as a winze, while when standing at the bottom, the opening is a raise, or rise.
