Llano Estacado (10)


Sediments shed from the rising mountains to the west formed the Llano Estacado, later to be bypassed by streams such as the Pecos and Canadian Rivers and left standing in bold relief with a relatively level, uneroded caprock surface. Croplands on the plain are irrigated using "fossil" water pumped from underground aquifers.

During World War II, New Mexico was the site of several top-secret military installations, including the Los Alamos National Laboratory, where the atomic bomb was developed. The laboratory is still one of the largest employers in the state and conducts research in fields such as nuclear energy and national security.
