Brown and Jackson's map of the Asir Quadrangle was part of the pioneering project to a complete geological and geographical survey of Saudi Arabia. The project was a collaboration between the Saudi Arabian Government and the U. S. Geological Survey. These maps form the basis for all modern maps of the Kingdom and are amongst the most important maps of the area ever produced. The Asir Quadrangle is the most southern part of Saudi Arabia and borders Yemen and the Red Sea.
