  It has been proposed recently that, within the framework of split
Supersymmetry, long lived gluinos generated in astrophysical sources could be
detected using the signatures of the air showers they produce, thus providing a
lower bound for their lifetime and for the scale of SUSY breaking. We present
the longitudinal profile and lateral spread of $G$-hadron induced extensive air
showers and consider the possibility of measuring them with a detector with the
characteristics of the Pierre Auger Observatory.
