We discuss the possibility to probe leptonic mixing parameters at high-energy neutrino telescopes in a model-independent way, using astrophysical neutron and pion sources. In particular we show how the octant of the 2-3 mixing angle might be determined independently of prior knowledge of the source, even when current uncertainties on the other mixing parameters are included. We also argue that nontrivial neutrino oscillation effects should be taken into account when using high-energy flavor ratios for astrophysical diagnostics.
