Draut, David M. Rubin, Jennifer L. Dierker, Helen C. Fairley, Ronald E. Griffiths, Joseph <br />E. Hazel, Jr, Ralph E. Hunter, Keith Kohl, Lisa M. Leap, Fred L. Nials, David J. Topping, and <br />Michael Yeatts <br /> <br />This report analyzes various depositional environments in three archaeologically significant areas of the Colorado River <br />corridor in Grand Canyon. Archaeological features are built on and buried by fluvial. aeolian. and locally derived sediment, <br />representing a complex interaction between geologic and cultural history. These analyses provide a basis for determining <br />the potential influence of Glen Canyon Dam operations on selected archaeological sites within the river corridor, intended to <br />facilitate preservation of cultural resources. <br /> <br />Scientific Investigations Report 2005-5072 <br /> <br />U.S. Department of the Interior <br />U.S. Geological Survey <br />
