Durango Bill's
Paleogeography (Historical Geology) Research
Appendix to the Evolution of the Colorado River and Its
Tributaries
Introduction
by
Bill Butler
The following sections
expand on the information used in the chronology section. Additional
evidence is given for some of the conclusions used - especially those
that disagree with currently accepted interpretations. Also, local
details are covered for areas near Durango, Colorado. Finally, as we
have noted throughout the paper, there has been a pattern of multiple
mountain uplifts throughout the Cenozoic. There has been a tendency for
these to occur along north-northwest to south-southeast axes. We will
present a trial theory as to the cause of these uplifts.
