Query: Probing Very High Energy Prompt Muon and Neutrino fluxes and the cosmic
  ray knee via Underground Muons   We calculate event rate and demonstrate the observational feasibility of very
high energy muons (1-1000 TeV) in a large mass underground detector operating
as a pair-meter. This energy range corresponds to surface muon energies of
$\sim$(5 TeV - 5000 TeV) and primary cosmic ray energies of $\sim$ (50 TeV - 5
$\times 10^4$ TeV). Such measurements would significantly assist in an improved
understanding of the prompt contribution to $\nu_e, \nu_{\mu}$ and $\mu$ fluxes
in present and future ultra-high energy neutrino detectors. In addition, they
would shed light on the origin of the observed 'knee' in the cosmic ray
spectrum.
