Los Alamos National Laboratory TA-49, Frijoles Mesa Site

Because the Frijoles Mesa Site is located near Bandelier National Monument, activities conducted there are restricted to carefully selected Laboratory functions. Currently, the Laboratory’s Hazardous Devices Team uses the site as a training area and as an isolated location for blowing up suspect packages. The site is also the location of the Laboratory’s Antenna and Pulse Power Outdoor Range User Facility, where a spectrum of outdoor tests is carried out on materials and equipment components that involve generating and receiving short bursts of high-energy, broad-spectrum microwaves. TA-49 is surrounded by a locked security fence, which prevents accidental intrusion. When experiments are conducted, personnel install barriers that exclude any individuals from access to areas where unsafe levels of energy could be encountered. In 1960 and 1961, a series of experiments involving high explosives and radioactive materials was conducted at the site. These experiments, which were primarily designed to improve the understanding of certain safety aspects of operational nuclear weapons, were conducted underground in large-diameter holes as deep as 120 ft (36.6 m).
