The discovery of a Higgs boson near 125 GeV, together with the absence of LHCsignals for supersymmetry or direct detection signals of dark matter, motivatefurther study of a particular theory of split supersymmetry. In arguably thetheoretically simplest implementation of split, the superpartner spectrum isspread over several decades. The squarks and sleptons are heavier than thegravitino and Higgsinos by a factor M_Pl/M_*, where M_* is the mediation scaleof supersymmetry breaking and is high, between unified and Planck scales. Onthe other hand the gaugino masses are 1-loop smaller than the gravitino andHiggsino masses, arising from both anomaly mediation and a Higgsino loop. Winodark matter arises from three sources: gravitino production by scattering athigh temperatures, gravitino production from squark decays, and thermalfreeze-out. For reheating temperatures larger than the squark mass, theseconspire to require that the squarks are lighter than about 10^4 TeV, whilecollider limits on gaugino masses require squarks to be heavier than about 100TeV. Whether winos constitute all or just a fraction of the dark matter, alarge fraction of the allowed parameter space has the gluino within reach ofthe LHC with 0.1 mm < c\tau_{\~g} < 10 cm, leading to displaced vertices. Inaddition, events with cascades via \~W^+- lead to disappearing charged trackswith c\tau_{\~W^+-} \sim 10 cm. The squarks and sleptons are predicted to bejust heavy enough to solve the supersymmetric flavor and CP problems. Thusgluino 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 electricdipole moment is expected to be of order 10^-29 ecm, two orders of magnitudebelow the current limit. The AMS-02 search for cosmic ray antiprotons willprobe an interesting region of parameter space.
