  We quantitatively address whether IceCube, a kilometer-scale neutrino
detector under construction at the South Pole, can observe neutrinos pointing
back at the accelerators of the Galactic cosmic rays. The photon flux from
candidate sources identified by the Milagro detector in a survey of the TeV sky
is consistent with the flux expected from a typical cosmic-ray generating
supernova remnant interacting with the interstellar medium. We show here that
IceCube can provide incontrovertible evidence of cosmic-ray acceleration in
these sources by detecting neutrinos. We find that the signal is optimally
identified by specializing to events with energies above 30 TeV where the
atmospheric neutrino background is low. We conclude that evidence for a
correlation between the Milagro and IceCube sky maps should be conclusive after
several years.
