  We report on a study of the potential of various cosmic ray physics
experiments to search for Standard Model processes involving the
nonperturbative production of O(30) weak gauge bosons. Whereas present and
near-future experiments are insensitive to proton-induced processes,
neutrino-induced processes give rise to promising signatures and rates in
AMANDA, DUMAND, MACRO and NESTOR provided that a cosmic neutrino flux exists at
levels suggested by recent models of active galactic nuclei. The Fly's Eye
currently constrains the largest region of parameter space characterizing
multi-W phenomena.
