Site selection for the Manhattan Project's three main centers of operation was no easy task. Each location had to meet a stringent list of criteria. In the end, officials picked the arid shrub-steppe of Eastern Washington for Hanford; the high desert of New Mexico for Los Alamos; and the rolling hills of East Tennessee for Oak Ridge. Today, these bustling communities are desginated as American World War II Heritage Cities.
