Los Alamos is a small town in northern New Mexico, about an hour northwest of Santa Fe. Its claim to fame is the Los Alamos National Laboratory (LANL), where Robert Oppenheimer and other physicists created the world's first atomic bomb during World War II. Many of Los Alamos's 12,000 residents work at the laboratory. White Rock, with about 6,000, is formally a part of Los Alamos, but is separated from the main town by LANL. Most of LANL is closed to the public. The Bradbury Science Museum located downtown, is a good place to learn about Los Alamos as is the Los Alamos Historical Society found next to Fuller Lodge.
