In geography and geology, fluvial processes are associated with rivers and streams and the deposits and landforms created by them. When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used.- Freemasonry (Wikipedia)
Freemasonry or Masonry refers to fraternal organisations guilds of stonemasons that, from the end of the 14th century, regulated the qualifications of stonemasons and their interaction with authorities and clients. Modern Freemasonry broadly consists of two main recognition groups: Regular Freemasonry, which insists that a volume of scripture be open in a working lodge, that every member professes belief in a Supreme Being, that no women be admitted, and that the discussion of religion and politics do not take place within the lodge; and Continental Freemasonry, which consists of the jurisdictions that have removed some, or all, of these restrictions.
