Los Alamos New Mexico Tourism

Los Alamos is built on the Pajarito Plateau between White Rock Canyon and the Valles Caldera. The mesas that the townsite resides on were created by glacial erosion during the last ice age.

The town of Los Alamos is divided up across four mesas—Barranca Mesa, North Mesa, Los Alamos Mesa and South Mesa – along with the connecting communities at the base of the mountain.
