If decays of superheavy relic particles in the galactic halo are responsiblefor ultrahigh-energy cosmic rays, these particles must be clustered to accountfor small-scale anisotropy in the AGASA data. We show that the masses of suchclusters are large enough for them to gravitationally lens stars and galaxiesin the background. We propose a general strategy that can be used to detectsuch clusters via gravitational lensing, or to rule out the hypothesis ofdecaying relic particles as the origin of highest-energy cosmic rays.Comment: 3 pages, one figure; references adde
