Within the framework of standard big-bang cosmology and the standard electroweak model, it is shown that ..nu..nu-bar annihilation on the Z resonance is the only cosmic-ray process sensitive to relic neutrinos. For massive (m/sub ..nu../> or approx. =10/sup -3/ eV) neutrinos originating from a zapprox.3 red-shifted source, a 15% to 50% absorption dip is predicted at E/sub ..nu../approx.10/sup 11/ GeV.
