Observations by the PAO indicate a correlation between UHECRs and either the local AGN or starburst galaxies. We consider whether this correlation is compatible with UHECRs having a single local extragalactic origin, and subsequently ballistically propagating in local extragalactic space before reverberating off the local Council of Giants structure. Focusing effects within the reverberation wave structure observed are discussed. We demonstrate that such a scenario imprints itself on the UHECR skymap, composed of both the direct and secondary waves from both the primary source local and the Council of Giant structure, respectively.
