Earth mysteries are a wide range of spiritual, quasi-religious and pseudoscientific ideas focusing on cultural and religious beliefs about the Earth, generally with regard to particular geographical locations of historical significance. Believers in Earth mysteries generally consider certain locations to be sacred, or that certain spiritual energies may be active at those locations. The term "alternative archaeology" has also been used to describe the study of Earth mystery beliefs. The study of ley lines originates in the 1920s with Alfred Watkins. The term "Earth mysteries" for this field of interest was coined about 1970 in The Ley Hunter journal, and the associated concepts have been embraced and reinvented by movements such as the New Age Movement and modern paganism during the 1970s to 1980s. Some New Age believers engage in travel to locations they consider important according to their beliefs; for example, Stonehenge is a popular destination amongst New Age seekers. History The concept of Earth mysteries can be traced back to two 17th-century antiquarians: John Aubrey and William Stukeley, who both believed that Stonehenge was associated with the druids. Stukeley mixed together ancient monuments and mythology towards an "idealized vision" of nature. "Ley lines" were postulated by Alfred Watkins in 1921 at a presentation at the Woolhope Naturalists' Field Club, later published in Early British Trackways (1922) and The Old Straight Track (1925). Watkins formed the Old Straight Track Club in 1927, which was active until 1935 but became defunct during the World War II period. A revival of interest in the topic began in the 1960s, now associated with neopagan currents like Wicca, and with ufology. Watkins' Straight Track Club was revived in 1962 by Philip Heselton and others as the Ley Hunters' Club. The new club's journal The Ley Hunter was issued from 1965 to 1970, subtitled "the Magazine of Earth Mysteries". British writer John Ivimy wrote a book in 1975 called The Sphinx and the Megaliths in which he linked the Egyptian Sphinx to the British Stonehenge and other megalithic structures claiming they were all built by a group of "elite trained" people. The New Age boom of the 1980s expanded the scope of the "Earth mysteries" field beyond the British landscape, and Earth mysteries as a "New Age invented tradition" by the 1990s could include the study of ancient sites and landscapes (including archaeology, archaeoastronomy, and ley lines), Chinese geomancy or feng shui, western magical
