Aboriginal petroglyphs found on Murujuga, also known as the Burrup Peninsula , in the Pilbara region of Australia. The peninsula contains the world's largest collection of petroglyphs, all of which are currently threatened by nearby natural gas mining operations.  The original creators of the petroglyphs-ancestors of the Yaburara people- no longer exist. The current claimants/custodians are the Ngarluma Yindjibarndi, Wong-goo-tt-oo and Yaburara Mardudhunera Aboriginal peoples. Photo by Jen Klewitz  Photo by Jen Klewitz
