In 10 years of observing the erosion of unconsolidated sediments at Providence Canyon State Park in southwestern Georgia, it is concluded that catastrophic events are more devastating or ruinous than slow, gradual processes. More erosional work was accomplished during a catastrophe than that observed in previous and later years of "normal" erosion. Also the evidence of a catastrophic erosional and depositional event can be obscured by later "normal" erosional processes.
