The astrophysical characteristics of primary cosmic rays (PCRs) and the structure of extensive air showers (EASs) with energy E{sub 0} {>=} 10{sup 17} eV are simultaneously analyzed using the Yakutsk EAS array data acquired in the period 1974-2005. Enhanced and reduced particle fluxes are shown to come from the disk of the Supergalaxy (the Local Supercluster of galaxies) at E{sub 0} {>=} 5 x 10{sup 18} eV and E{sub 0} {<=} (2-3) x 10{sup 18}, respectively. The development of air showers with E{sub 0} {>=} (3-5) x 10{sup 18} eV differs significantly from that at lower energies. This is interpreted as a manifestation of the possible interaction between extragalactic PCRs and the matter of this spatial structure.
