Information: - 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, and it occupies a total of . Very small areas also extend into Utah and Arizona. Its boundaries are generally noted by the presence of Joshua trees, which are native only to the Mojave Desert and are considered an indicator species, and it is believed to support an additional 1,750 to 2,000 species of plants. The central part of the desert is sparsely populated, while its peripheries support large communities such as Las Vegas, Lancaster, Palmdale, Victorville, and St. George. - A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification. - Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms and/or chords of a song or instrumental musical piece. Like its analogs printed books or pamphlets in English, Arabic or other languages the medium of sheet music typically is paper (or, in earlier centuries, papyrus or parchment), although the access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments. - Warner Leroy Baxter (March 29, 1889 May 7, 1951) was an American actor, known for his role as The Cisco Kid in "In Old Arizona" (1929), for which he won the second Academy Award for Best Actor in the 19281929 Academy Awards. He frequently played womanizing, charismatic Latin bandit types in westerns, and played The Cisco Kid or a similar character throughout the 1930s, but had a range of other roles throughout his career. Warner Baxter started his movie career in silent film. Baxter's most notable silent films are "The Great Gatsby" (1926) and "The Awful Truth" (1925). When talkies came out, Baxter became even more famous. Baxter's most notable talkies are "In Old Arizona" (1929), "42nd Street" (1932), "Slave Ship" (1937), "Kidnapped" (1938), and the 1931 20 minute all-star ensemble short film, "The Stolen Jools". In the 1940s he was well known for his recurring role as Dr. Robert Ordway in the Crime Doctor series of 10 films. - The Stolen Jools (1931) is a short comedy film produced by the Masquers Club of Hollywood, featuring many cameo appearances by film stars of the day. The stars appeared in the film, distributed by Paramount Pictures, to raise funds for the National Vaudeville Artists Tuberculosis Sanitarium. The UCLA Film and Television Archive entry for this film saysas do the creditsthat the film was co-sponsored by Chesterfield cigarettes to support the "fine work" of the NVA sanitarium. - The Library of Congress ("LOC") is the research library that officially serves the United States Congress and is the "de facto" national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center. - A gold rush is a new discovery of gold that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, New Zealand, Brazil, Canada, South Africa and the United States, while smaller gold rushes took place elsewhere. - Paramount Pictures Corporation (known professionally as Paramount Pictures and often referred to simply as Paramount) is an American film studio based in Hollywood, California, that has been a subsidiary of the American media conglomerate Viacom since 1994. Paramount is the fifth oldest surviving film studio in the world, the second oldest in the United States, and the sole member of the "Big Six" film studios still located in the Los Angeles neighborhood of Hollywood. In 1916 Zukor contracted 22 actors and actresses and honored each with a star on the logo. These fortunate few would become the first "movie stars." Paramount Pictures is a member of the Motion Picture Association of America (MPAA). - The Motion Picture Association of America (abbreviated as MPAA) is an American trade association that represents the six major Hollywood studios. It was founded in 1922 as the Motion Picture Producers and Distributors of America (MPPDA) to advance the business interests of its members. In its formative years it took on the role of devising guidelines for film content which resulted in the creation of the Production Code, and currently administers the MPAA film rating system. - Death Valley National Park is a national park in the United States. Straddling the border of California and Nevada, located east of the Sierra Nevada, it occupies an interface zone between the arid Great Basin and Mojave deserts in the United States. The park protects the northwest corner of the Mojave Desert and contains a diverse desert environment of salt-flats, sand dunes, badlands, valleys, canyons, and mountains. It is the largest national park in the lower 48 states and has been declared an International Biosphere Reserve. Approximately 91% of the park is a designated wilderness area. It is the hottest, driest and lowest of the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is below sea level. The park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, bighorn sheep, coyote, and the Death Valley pupfish, a survivor of much wetter times. - Adolph Zukor (January 7, 1873 June 10, 1976) was an American film mogul and founder of Paramount Pictures. - Rhyolite is a ghost town in Nye County, in the U.S. state of Nevada. It is in the Bullfrog Hills, about northwest of Las Vegas, near the eastern edge of Death Valley. The town began in early 1905 as one of several mining camps that sprang up after a prospecting discovery in the surrounding hills. During an ensuing gold rush, thousands of gold-seekers, developers, miners and service providers flocked to the Bullfrog Mining District. Many settled in Rhyolite, which lay in a sheltered desert basin near the region's biggest producer, the Montgomery Shoshone Mine. - A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its "CategoryII" type of protected areas. - The Academy Award for Best Actor is an award presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS). It is given in honor of an actor who has delivered an outstanding performance in a leading role while working within the film industry. - Mean sea level (MSL) (abbreviated simply sea level) is an average level of the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datuma standardised geodetic reference pointthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location. - The Cisco Kid is a fictional character found in numerous film, radio, television and comic book series based on the fictional Western character created by O. Henry in his 1907 short story "The Caballero's Way", published in the collection "Heart of the West", as well as in "Everybody's Magazine", v17, July 1907. In movies, radio and television, the Kid was depicted as a heroic Mexican caballero, even though he was originally a cruel outlaw. - COYOTE is an American rights organization. Its name is a backronym for "C"all "O"ff "Y"our "O"ld "T"ired "E"thics, a reflection of the fact that sex work tends to be stigmatized primarily because of society-imposed standards of ethics. COYOTE's goals include the decriminalization (as opposed to the legalization) of prostitution, pimping and pandering, as well as the elimination of social stigma concerning sex work as an occupation. - Irvin Willat (November 18, 1890 April 17, 1976) was an American film director of the silent film era. He directed 39 films between 1917 and 1937. Early in his career Willat worked as a cinematographer on several films. - A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936. In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards which contain a written indication of the plot or key dialogue. The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was only made practical in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system. During silent films, a pianist, theatre organist, or, in large cities, even a small orchestra would often play music to accompany the films. Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music. - Death Valley is a desert valley located in Eastern California. It is one of the hottest places in the world at the height of summertime along with deserts in Africa and in the Middle East. - Viacom, Inc. (known simply as Viacom) is an American media conglomerate with interests primarily in cinema and cable television. It is currently the world's sixth largest broadcasting and cable company in terms of revenue, behind Comcast, The Walt Disney Company, Time Warner, 21st Century Fox and CBS Corporation, respectively. Voting control of Viacom is held by National Amusements, Inc., a privately owned theater company controlled by the billionaire Sumner Redstone. Redstone also holds via National Amusements a controlling stake in CBS Corporation. - The Death Valley pupfish ("Cyprinodon salinus"), also known as Salt Creek pupfish, is found in Death Valley National Park. There are two recognized subspecies: "C. s. salinus" and "C. s. milleri". It is endemic to two small, isolated locations and currently classified as endangered. - Famous Players-Lasky Corporation was an American motion picture and distribution company created on July 19, 1916, from the merger of Adolph Zukor's Famous Players Film Companyoriginally formed by Zukor as Famous Players in Famous Playsand Jesse L. Lasky's Feature Play Company. - A theatre organ (also known as a theater organ, or [especially in the U.K.] a cinema organ) is a distinct type of pipe organ originally developed to provide music and sound effects to accompany silent films during the first 3 decades of the 20th century. - A national library is a library specifically established by the government of a country to serve as the preeminent repository of information for that country. Unlike public libraries, these rarely allow citizens to borrow books. Often, they include numerous rare, valuable, or significant works. A National Library is that library which has the duty of collecting and preserving the literature of the nation within and outside the country, Thus, National Library are those libraries whose community is the nation at large. Examples include; The British Library, The Bibliotheque Nationale In Paris. - A media conglomerate, media group, or media institution is a company that owns numerous companies involved in mass media enterprises, such as television, radio, publishing, motion pictures, theme parks, or the Internet. According to the magazine "Nation", "Media conglomerates strive for policies that facilitate their control of the markets around the world." - The United States Congress is the bicameral legislature of the federal government of the United States consisting of two chambers: the Senate and the House of Representatives. The Congress meets in the Capitol in Washington, D.C. Both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a gubernatorial appointment. Members are usually affiliated to the Republican Party or to the Democratic Party, and only rarely to a third party or as independents. Congress has 535 voting members: 435 Representatives and 100 Senators. The House of Representatives has six non-voting members in addition to its 435 voting members. These members can, however, sit on congressional committees and introduce legislation. These members represent Washington, D.C., Puerto Rico, American Samoa, Guam, the Northern Mariana Islands and the U.S. Virgin Islands. - Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. They can resemble malpais, a terrain of volcanic rock. Canyons, ravines, gullies, buttes, mesas, hoodoos and other such geological forms are common in badlands. They are often difficult to navigate by foot. Badlands often have a spectacular color display that alternates from dark black/blue coal stria to bright clays to red scoria. - California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. - Hollywood (, informally Tinseltown ) is an ethnically diverse, densely populated, relatively low-income neighborhood in the central region of Los Angeles, California. It is notable as the home of the U.S. film industry, including several of its historic studios, and its name has come to be a shorthand reference for the industry and the people in it. - The Famous Players Film Company or Celebrated Players was a film company.It was founded in 1912 by Adolph Zukor in partnership with the Frohman brothers, the powerful New York City theatre impresarios. Discussions to form the company were held at The Lambs, the famous theater club where Charles and Daniel Frohman were members. The company advertised "Famous Players in Famous Plays" and its first release was the French film "Les Amours de la reine Elisabeth" (1912) starring Sarah Bernhardt and Lou Tellegen. Its first actual production was "The Count of Monte Cristo" (1912, released 1913), directed by Edwin S. Porter and starring James O'Neill, the father of dramatist Eugene O'Neill. The company established a studio on 26th Street in New York City that today is Chelsea Studios. - The Bullfrog Hills are a small mountain range of the Mojave Desert in southern Nye County, southwestern Nevada. - A film studio (also known as movie studio or simply studio) is a major entertainment company or motion picture company that has its own privately owned studio facility or facilities that are used to make films, which is handled by the production company. The majority of firms in the entertainment industry have never owned their own studios, but have rented space from other companies. - In Old Arizona is a 1928 American Pre-Code Western film directed by Irving Cummings and Raoul Walsh, nominated for five Academy Awards, including Best Picture. The film, which was based on the character of the Cisco Kid in the story "The Caballero's Way" by O. Henry, was a major innovation in Hollywood. It was the first major Western to use the new technology of sound and the first talkie to be filmed outdoors. It made extensive use of authentic locations, filming in Bryce Canyon National Park and Zion National Park in Utah, and the San Fernando Mission and the Mojave Desert in California. The film premiered in Los Angeles on December 25, 1928 and went into general release on December 28, 1928 or January 20, 1929. - A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects. - Virginia (, officially the Commonwealth of Virginia) is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. Virginia is nicknamed the "Old Dominion" due to its status as the first colonial possession established in mainland British America, and "Mother of Presidents" because eight U.S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth's estimated population is over 8.3 million, which is slightly less than New York City. - A ghost town is an abandoned village, town, or city, usually one that contains substantial visible remains. A town often becomes a ghost town because the economic activity that supported it has failed, or due to natural or human-caused disasters such as floods, government actions, uncontrolled lawlessness, war, or nuclear disasters. The term can sometimes refer to cities, towns, and neighborhoods that are still populated, but significantly less so than in years past; for example those affected by high levels of unemployment and dereliction. - A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid. This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. - Badwater Basin is an endorheic basin in Death Valley National Park, Death Valley, Inyo County, California, noted as the lowest point in North America, with an elevation of below sea level. Mount Whitney, the highest point in the contiguous 48 United States, is only to the north west. - An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments. - Nevada (Spanish for "snowy"; see pronunciations) is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, and the 9th least densely populated of the 50 United States. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las VegasParadise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital is Carson City. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State", because it achieved statehood during the Civil War (the words "Battle Born" also appear on the state flag); as the "Sage-brush State", for the native plant of the same name; and as the "Sage-hen State". Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east. - A film director is a person who directs the making of a film. Generally, a film director controls a film's artistic and dramatic aspects, and visualizes the script while guiding the technical crew and actors in the fulfillment of that vision. The director has a key role in choosing the cast members, production design, and the creative aspects of filmmaking. Under European Union law, the director is viewed as the author of the film. - Los Angeles (Spanish for "The Angels"), officially the City of Los Angeles and often known by its initials L.A., is the second-most populous city in the United States (after New York City), the most populous city in California and the county seat of Los Angeles County. Situated in Southern California, Los Angeles is known for its mediterranean climate, ethnic diversity, sprawling metropolis, and as a major center of the American entertainment industry. Los Angeles lies in a large coastal basin surrounded on three sides by mountains reaching up to and over . - A pianist is an individual musician who plays the piano. Most forms of Western music can make use of the piano. Consequently, pianists have a wide variety of repertoire and styles to choose from, including traditionally classical music, Jazz, blues and all sorts of popular music, including rock music. Most pianists can, to a certain extent, play other keyboard-related instruments such as the synthesizer, harpsichord, celesta and the organ and keyboard. Perhaps the greatest pianist of all time was Franz Liszt, whose piano mastery was described by Anton Rubinstein: "In comparison with Liszt, all other pianists are children". - The bighorn sheep ("Ovis canadensis") is a species of sheep native to North America named for its large horns. These horns can weigh up to , while the sheep themselves 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. - Vitaphone was a sound film system used for feature films and nearly 1,000 short subjects made by Warner Bros. and its sister studio First National from 1926 to 1931. Vitaphone was the last major analog sound-on-disc system and the only one which was widely used and commercially successful. The soundtrack was not printed on the film itself, but issued separately on phonograph records. The discs, recorded at rpm (a speed first used for this system) and typically in diameter, would be played on a turntable physically coupled to the projector motor while the film was being projected. Many early talkies, such as "The Jazz Singer" (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound". - The National Audiovisual Conservation Center, also known as the Packard Campus for Audio-Visual Conservation, is the Library of Congress's new audiovisual archive located inside Mount Pony in Culpeper, Virginia. - Dialogue (sometimes spelled dialog in U.S. English) is a written or spoken conversational exchange between two or more people, and a literary and theatrical form that depicts such an exchange. As a narrative, philosophical or didactic device, it is chiefly associated in the West with the Socratic dialogue as developed by Plato, but antecedents are also found in other traditions including Indian literature. In the 20th century, philosophical treatments of dialogue emerged from thinkers including Mikhail Bakhtin, Paulo Freire, Martin Buber, and David Bohm. Although diverging in many details, these thinkers have articulated a holistic concept of dialogue as a multi-dimensional, dynamic and context-dependent process of creating meaning. Educators such as Freire and Ramon Flecha have also developed a body of theory and technique for using egalitarian dialogue as a pedagogical tool. - In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is often problematic. For example, in a species complex, the boundaries between closely related species become unclear or disappear altogether. Other ways of defining species include similarity of DNA, morphology, or ecological niche. The presence of locally adaptive traits may further subdivide species into infraspecific taxa such as subspecies. - The Air Mail is a 1925 silent film directed by Irvin Willat and starring Warner Baxter , Billie Dove , and Douglas Fairbanks , Jr. . It was produced by Famous Players - Lasky and distributed through Paramount Pictures . Filmed in Death Valley National Park and the ghost town of Rhyolite , Nevada , it was released in the United States on March 16 , 1925 . Only four of eight reels survive in the Library of Congress .
