Los Alamos Historical Museum

The Los Alamos Historical Museum is housed in the historic Guest House, located next to Fuller Lodge, of Los Alamos Ranch School, which was General Leslie Groves's favorite place to stay during the Manhattan Project.

The museum features exhibits on the geological history of the Pajarito Plateau, including the volcanic explosion that created the world's second largest caldera, known as the Valles Caldera. It also has displays on the early settlers of the area, the Ancestral Pueblo Indians and the early homesteaders. The museum displays the history of the Los Alamos Ranch School, an elite educational institution for wealthy boys.
