  We compare the tau neutrino flux arising from the galaxy and the earth
atmosphere for $10^{3} \leq E/{GeV} \leq 10^{11}$. The intrinsic and oscillated
tau neutrino fluxes from both sources are considered. We find that, for $E\geq
10^3$ GeV, the oscillated $\nu_{\tau}$ flux along the galactic plane dominates
over the maximal intrinsic atmospheric $\nu_{\tau}$ flux, i.e., the flux along
the horizontal direction. We also briefly comment on the prospects for
observing these high-energy tau neutrinos.
