The article discusses the change in the elastic properties of rockfill in the rims of an open pit dump during natural compaction under the climate impacts. Seismic survey records allowed determining limits of seasonal change in the dynamic elasticity modulus in freeze of the upper layer of dump rockfill. It is shown that dynamic Young’s modulus is exceeded 1.5 times. The results are reflective of activation of natural self-organization in rocks in the rims of an open pit dump under the natural climate impact as the strength increases in the surface layers of the dump.
