holes, vertical shafts, and horizontal tunnels at the Nevada Test Site, now known as the Nevada National Security Site (NNSS). Most vertical shaft tests assisted in the development of new weapon systems. Horizontal tunnel tests occurred to evaluate the effects (radiation, ground shock) of various weapons on military hardware and systems. Background
