||Sixty years have passed since the Mount Everest was first conquered. The popularity of its scaling and the rapidly growing tourism in the Nepal Himalayas after 1970 are noticeably affecting natural, social, and cultural environments in the vicinity. This in turn, is creating serious environmental problems at the Everest Base Camp (5,300 m above mean sea level), the entry point for climbing the Mt. Everest. In this study, our research objective was to elucidate the relationship between mountaineering activities and associated environmental changes by applying GIS and remote sensing, so that further degradation of present environmental conditions could be stopped.
