We focus on the arrival direction distributions of the ultra-high energy cosmic rays (UHECR) in search of their possible origins. Models which associate the origin of UHECR with decays of relic superheavy dark matter particles (SHDM) predict the anisotropy of UHECR flux toward the Galactic center. We use the existing SUGAR data, which cover the Galactic center, to look for such a signal and limit the fraction of UHECR produced by this mechanism.
