Haunted Mesa is a science fiction novel by Louis L'Amour, set in the American Southwest amidst the ruins of the Anasazi.
 L'Amour attempts, as in others of his works, to suggest a reasonable explanation for the phenomena attributed to The Bermuda Triangle, i.e., portals between worlds or different facets of this world.
 The same phenomenon is used, albeit in a very minor way, in his novel "The Californios."
 A useful contrast between the two novels is that in "The Haunted Mesa," the Anasazi leadership, who rule both the portals and their people with an iron hand (the Hand and the Voice are two of the leaders), are corrupt and thoroughly evil, whereas the person or people who know about the portal in "The Californios" are reserved and rather helpful to people they respect.
 These were different portals however, and did not necessarily lead to the same location.
Stephen L. Nelson (born 1959) is the author of more than 160 books about using personal computers, including "Quicken for Dummies", "QuickBooks for Dummies", "MBA's Guide to Microsoft Excel", and "Excel Data Analysis for Dummies".
 The Wall Street Journal once called him the Louis L'Amour of computer books because at the time (December 2000), he had written more computer books than any other author.
David Herbert Lawrence (11 September 1885 – 2 March 1930) was an English novelist, poet, playwright, essayist, literary critic and painter.
 His collected works represent, among other things, an extended reflection upon the dehumanising effects of modernity and industrialisation.
 Some of the issues Lawrence explores are sexuality, emotional health, vitality, spontaneity, and instinct.
The National Association for Chiropractic Medicine (NACM) was a minority chiropractic association founded in 1984 that described itself as a "consumer advocacy association of chiropractors".
 It openly rejected some of the more controversial aspects of chiropractic, including a basic concept of chiropractic, vertebral subluxations as the cause of all diseases.
 It also sought to "reform the chiropractic profession away from a philosophical scope of practice and towards an applied science scope of practice."
 It stated that it was "dedicated to bringing the scientific based practice of chiropractic into mainstream medicine" and that its members "confine their scope of practice to scientific parameters and seek to make legitimate the utilization of professional manipulative procedures in mainstream health care delivery."
 "While the NACM is focused on furthering the profession, its primary focus is on the rights and safety of the consumers."
 The NACM was the object of much controversy and criticism from the rest of the profession.
 It quietly dropped out of sight and its demise apparently occurred sometime between May 30, 2008 and March 6, 2010.
Last of the Breed, a 1987 book by Louis L'Amour, tells the fictional story of Native American United States Air Force pilot Major Joseph Makatozi (Joe Mack), shot down by the Soviets over the ocean between Russia and Alaska and then captured.
 Although the exact time is never stated, it appears to be the mid- to late 1980s, as Mikhail Gorbachev's rise to power is mentioned.
 It was L'Amour's second-to-last published novel.
Yondering is a collection of short stories by American author Louis L'Amour, published in 1980.
 A departure from L'Amour's traditional subject matter of the Old West, "Yondering" contains a mix of adventure stories and character studies, primarily set in the first half of the 20th century.
 Two of them are set during the World War II era, with many of the stories drawing upon the author's own life experiences.
 The book's publication celebrated the milestone of L'Amour having an estimated 100 million books in print at that time of publication.
Optometry is a health care profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.
 Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles.
 Modern day optometry, however, has evolved through time so that the education curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated.
 Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D. degree or Ophthalmic Opticians in the UK) are medical professionals who provide primary eyecare through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases.
 Being a regulated profession, an optometrist's scope of practice may differ depending on the location.
 Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are physicians that specialize in tertiary medical and surgical care of the eye.
 Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eyecare to the general public.
Louis Dearborn L'Amour ( ; March 22 1908 –June 10 1988) was an American novelist and short story writer.
 His books consisted primarily of Western novels (though he called his work 'frontier stories'); however, he also wrote historical fiction ("The Walking Drum"), science fiction ("The Haunted Mesa"), non-fiction ("Frontier"), as well as poetry and short-story collections.
 Many of his stories were made into films and John Wayne once made the dubious assertion that L'Amour was the most interesting man in the world.
 L'Amour's books remain popular and most have gone through multiple printings.
 At the time of his death almost all of his 105 existing works (89 novels, 14 short-story collections, and two full-length works of nonfiction) were still in print, and he was considered "one of the world's most popular writers".
Hondo is a 1953 Warnercolor 3D Western film directed by John Farrow and starring John Wayne and Geraldine Page.
 The screenplay is based on the July 5, 1952 Collier's short story "The Gift of Cochise" by Louis L'Amour.
 The book "Hondo" was a novelization of the film also written by L'Amour, and published by Gold Medal Books in 1953.
 The supporting cast features Ward Bond, James Arness and Leo Gordon.
Kipling Morgan, better known as Kip Morgan was a fictional character created by the bestselling author Louis L'Amour.
 Morgan is a detective, like the hard-boiled detective characters created by Dashiell Hammett and Raymond Chandler.
 In L'Amour's words, "Kip Morgan is an ex-prizefighter struggling to make a new career himself as a private operator."
 L'Amour wrote a few short stories featuring Morgan including "Dead Man's Trail", "With Death in His Corner" and "The Street of Lost Corpses".
 Several of the stories make up the latter third of Vol.
