ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by George Steinmetz @geosteinmetz | A rare helicopter view of Puncak Jaya, the highest point (16,024 feet) on the greater Australian continent. It’s the spine of New Guinea—and a great example of the force of continental collision. The peak is awkward to access, as it’s adjacent to the world’s largest gold and copper mine, Grasberg (at right), the source of great wealth for some and of conflict for the locals. This view is from 1993, when I spent a year in Irian Jaya (now West Papua) on assignment for @natgeo. It took a lot of convincing mine management to get my butt on that chopper. #sevensummits #carstenszpyramid To explore more of our world from above, follow @geosteinmetz.」12月24日 0時38分
