In 1931 Harvey Spencer Lewis using the pseudonym Wisar Spenle Cerve wrote a book (published by the Rosicrucians) about the hidden Lemurians of Mount Shasta that a bibliography on Mount Shasta described as responsible for the legend's widespread popularity. This belief has since been repeated by Guy Warren Ballard and the followers of the Ascended Masters and the Great White Brotherhood, The Bridge to Freedom, The Summit Lighthouse, Church Universal and Triumphant and Kryon.
