The Geological Society of America (or GSA) is a nonprofit organization dedicated to the advancement of the geosciences. The society was founded in New York in 1888 and has been headquarted at 3300 Penrose Place, Boulder, Colorado since 1968. As of 2004, the society has over 16,000 members in more than 85 countries. The stated mission of GSA is "to advance the geosciences, to enhance the professional growth of its members, and to promote the geosciences in the service of humankind". Its main activities are sponsoring scientific meetings and publishing scientific literature, particularly the GSA Bulletin and the journal Geology. It also publishes a monthly newspaper, GSA Today. The society has six regional sections in North America and fifteen specialty divisions.
The GSA began with 100 members under its first president, James Hall. Over the next 43 years it grew slowly but stably to 600 members until 1931, when a $4 million endowment from 1930 president R.A.F.

The Geologic Map of North America (published February 2005) portrays the grand architecture of the continent as we understood it in the closing years of the 20th century.
The resulting Geologic Map of North America is designed to depict bedrock and less indurated sedimentary units at or near the surface throughout all parts of the North American continent, as well as selected parts of adjacent continents and islands.
During compilation of the geologic map some corrections were made to the base, chiefly in northeastern Greenland and in the overlap area between the northern and southern sheets.
