The MINOS far detector, a scintillator tracker instrumented
for nanosecond timing which will accumulate a non-accelerator exposure of
several kiloton-decades, provides opportunity to identify reactions 
of few GeV visible energy which yield ${\rm K}^{+}$ meson(s).   
Interactions of this type comprise a major portion of strangeness
production initiated by atmospheric neutrinos.  
Such events, upon full reconstruction, will exhibit a distinctive 
``twin peaks" time profile 
for which light of the primary interaction gives the
initial pulse and the subsequent ${\rm K}^{+}$ decay nearby yields 
a second pulse delayed by few tens of nanoseconds. 
By measuring the heretofore unresolved atmospheric \neut~strangeness 
production component, MINOS can set a benchmark 
for experiments striving for improved lifetime limits on SUSY
proton decay ${\rm p} \rightarrow {\rm K}^{+} \nu$.
Additionally MINOS can enable first-ever limit-setting or discovery
of a baryon instability mode predicted
in certain unification models, namely $\Delta S = 2$ double
nucleon decay within nuclei,
e.g. ${\rm D} \rightarrow {\rm K}^{+} {\rm K}^{*}$.
