Terrain of the Canadian River valley in the vicinity
of the Hajny Mammoth locality, which is in Section 16-17N-15W, Dewey County,
Oklahoma. The view is to the northeast. The alluvial terrace system of the
Canadian is clearly visible as a sequence of progressively higher benches above
the modern river. Each terrace represents an interglacial period of climatic
stability in the 100,000 year glacial cycle of the last 600,000 years. The
downcutting events that separate these terraces occurred in the wetter, gyrating
climate of the full glacials.
