In 2004, after 40 years of work, the Geological Survey of Denmark and Greenland (GEUS) completed the geological survey mapping of Greenland. Hundreds of geologists have spent many summers studying the rocks, resulting in 14 geological maps representing an overview of the rocks and structures of the ice-free parts of Greenland. The 14 maps are published on the scale of 1:500,000, meaning that 1 cm on the map corresponds to 5 km in nature. The first of these map sheets was published in 1971, and the fourteenth and last in 2004.
