  We examine the experimental signatures for the production of gluinos at
colliders and in cosmic rays within the split supersymmetry scenario. Unlike in
the MSSM, the gluinos in this model are relatively long-lived due to the large
value of the squark masses which mediate their decay. Searches at colliders are
found to be sensitive to the nature of gluino fragmentation as well as the
gluino-hadron interactions with nuclei and energy deposition as it traverses
the detector. We find that the worst-case scenario, where a neutral
gluino-hadron passes through the detector with little energy deposition, is
well described by a monojet signature. For this case, using Run I data we
obtain a bound of $m_{\tilde g} > 170$ GeV; this will increase to 210(1100) GeV
at Run II(LHC) if no excess events are observed. In the opposite case, where a
charged gluino-hadron travels through the detector, a significantly greater
reach is obtained via stable charged particle search techniques. We also
examine the production of gluino pairs in the atmosphere by cosmic rays and
show they are potentially observable at IceCube; this would provide a
cross-check for observations at hadron colliders.
