Figure 6, High Resolution
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.
