Pantex was built during World War II near the town of Amarillo, Texas. The site was converted early in the Cold War to assemble nuclear weapons and produce high explosives. For nearly fifty years Pantex has been the sole assembly and disassembly plant for nuclear weapons in the United States. Today, most of the activities of the plant consist of the manufacture of high explosive components and the dismantlement or life extension of weapons. Unlike the much more famous nuclear-weapons-production sites at Los Alamos, Oak Ridge, Hanford, and Rocky Flats, the Pantex plant has drawn little attention, hidden under a metaphoric "cap of invisibility." Lucie Genay now lifts that invisibility cap to give the world its first in-depth look at Pantex and the people who have spent their lives as neighbors and employees of this secretive industry. The book investigates how Pantex has impacted local identity by molding elements of the past into the guaranty of its future and its concealment. It further examines the multiple facets of Pantexism through the voices of native and adoptive Panhandlers.

In this thoughtful social history of New Mexico's nuclear industry, Lucie Genay traces the scientific colonization of the state in the twentieth century from the points of view of the local people. Genay focuses on personal experiences in order to give a sense of the upheaval that accompanied the rise of the nuclear era. She gives voice to the Hispanics and Native Americans of the Jemez Plateau, the blue-collar workers of Los Alamos, the miners and residents of the Grants Uranium Belt, and the ranchers and farmers who were affected by the federal appropriation of land in White Sands Missile Range and whose lives were upended by the Trinity test and the US government's reluctance to address the "collateral damage" of the work at the range. Genay reveals the far-reaching implications for the residents as New Mexico acquired a new identity from its embrace of nuclear science.
