National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by Simon Norfolk @simonnorfolkstudio I The Kersten Glacier margin, just below Uhuru Peak, with Mount Meru in the distance, photographed whilst climbing Mount Kilimanjaro, Tanzania. Despite continuing shrinkage of Kilimanjaro's glaciers, the steep margins of the Kersten Glacier remain impressive—the cliff is approximately 18 m. (60 ft.) high. The dust bands in the ice absorb more solar radiation than the surrounding, relatively-clean ice, and absorbed energy leads to melting and sublimation. Such stratigraphy is testimony to the complex ice history on Kilimanjaro. Follow me, @simonnorfolkstudiofor, for updates, outtakes, and unpublished and archive material on this and future projects. #photojournalism #Kilimanjaro #climatechange #glaciers」7月3日 7時01分
