  We show that LSG model predictions of event ratios are clearly distinguished
from those of the SM. This is true in all models of ultrahigh energy (UHE)
neutrino sources, in both $\nu_e:\nu_{\mu}:\nu_{\tau} = 1:1:1$ and
$\nu_e:\nu_{\mu}:\nu_{\tau} = 1:2:0$ scenarios for the flux incident on earth.
In particular the ratios of upward $\mu$ events to upward shower events and the
ratios of up events to down events are different by a factor of 2 to an order
of magnitude in the comparisons between SM and LSG. $\nu_{\tau}$ rates are low
but show high sensitivity to SM vs LSG interaction physics.
