AMBER WAVES OF GRAIN. This field of ceramic nose-cones represents, in miniature, all the warheads in the US nuclear arsenal at the height of the Cold War, along with the nuclear submarines, bombers, and ballistic missiles designed to deliver them. Estimates put the warhead count at around 25,000. Denver sculptress Barbara Donachy created this installation to show what such a concentration of nuclear weaponry would look like all in one place. Her display contains 33,561 pieces representing 31,000 warheads, 1,799 ballistic missiles, 324 intercontinental bombers, and 37 nuclear submarines.
