Although the first scientific efforts in geomorphology, <br /> <br /> <br />biology and ethnography in the Canyon were developed by John Wesley Powell in 1869, the <br /> <br />majority of scientific accomplishment in the Colorado River corridor between Glen Canyon <br /> <br />Dam and Lake Mead has been accomplished under the guidance of BaR since 1982. Since <br /> <br />that time, the BaR Glen Canyon Environmental Studies Program (GeES) has initiated a <br /> <br />significant number of research studies and monitoring activities to detennine baseline <br /> <br />conditions and associated change in many physical, biological, cultural and socioeconomic <br /> <br />resources. <br /> <br />Over a period of thirteen years, the GCES and other agencies and research entities <br /> <br />developed extensive databases in many different resource areas. Further scientific analysis in <br /> <br />many of these areas permitted identification of some of the important attributes associated <br /> <br />with changes in critical resources.
