This was a product of the groundbreaking mapping project USGS conducted for the Saudi Government with Aramco during 1956-63. This mapped Saudi Arabia in 21 Quadrangles on a 1/500K scale with one series for geology (I-200A to I-220A) and another for geography (I-200B to I-220B). It involved some of the most eminent geologists of the day, among them Glen Brown (USGS), Richard Bramkamp and Max Steineke (Aramco's early pioneers). The work provided the foundation for the Saudi Arabian Mineral Exploration Project launched in 1963, coordinated by Brown from Jeddah. Titled and captioned with Glossary and compilation sources in English and Arabic, features include settlements (including forts, ruins, cultivated areas, date gardens). Transport covers from roads to camel trails, rail and landing fields.
