  The discovery of a Higgs boson near 125 GeV, together with the absence of LHC
signals for supersymmetry or direct detection signals of dark matter, motivate
further study of a particular theory of split supersymmetry. In arguably the
theoretically simplest implementation of split, the superpartner spectrum is
spread over several decades. The squarks and sleptons are heavier than the
gravitino and Higgsinos by a factor M_Pl/M_*, where M_* is the mediation scale
of supersymmetry breaking and is high, between unified and Planck scales. On
the other hand the gaugino masses are 1-loop smaller than the gravitino and
Higgsino masses, arising from both anomaly mediation and a Higgsino loop. Wino
dark matter arises from three sources: gravitino production by scattering at
high temperatures, gravitino production from squark decays, and thermal
freeze-out. For reheating temperatures larger than the squark mass, these
conspire to require that the squarks are lighter than about 10^4 TeV, while
collider limits on gaugino masses require squarks to be heavier than about 100
TeV. Whether winos constitute all or just a fraction of the dark matter, a
large fraction of the allowed parameter space has the gluino within reach of
the LHC with 0.1 mm < c\tau_{\~g} < 10 cm, leading to displaced vertices. In
addition, events with cascades via \~W^+- lead to disappearing charged tracks
with c\tau_{\~W^+-} \sim 10 cm. The squarks and sleptons are predicted to be
just heavy enough to solve the supersymmetric flavor and CP problems. Thus
gluino decay modes may typically violate flavor and involve heavy quarks:
[\bar{t}(t,c,u)+\bar{b}(b,s,d)] \~W^0 and
[\bar{t}(b,s,d)+(\bar{t},\bar{c},\bar{u})b] \~W^+-. The electron electric
dipole moment is expected to be of order 10^-29 ecm, two orders of magnitude
below the current limit. The AMS-02 search for cosmic ray antiprotons will
probe an interesting region of parameter space.
