Chajnantor Plateau

This is the view of the Chajnantor Plateau that greeted NRAO astronomers who were exploring the northeastern region of Chile as a potential site for a millimeter/submillimeter wave telescope array then known as the MMA. The high altitude of 16,500 feet and the flat expanse were perfect for our needs. European and Japanese radio astronomers agreed, and we pooled our projects to build ALMA here.
