I'm Dr. Fred Hiebert, a National Geographic archaeologist andexplorer. I'm currently in Kyrgyzstan on the northern shore of Issyk Kul, one of the world’s highest and deepest lakes, to look for the underwater remains of a palace associated with the infamous conqueror Tamerlane. I've also led excavations at ancient sites across Central Asia and searched for submerged settlements in the Black Sea and South America. I've lived in yurts, eaten sheep eyes and had a museum built for the world's oldest grain of bread wheat found by our expedition in Turkmenistan. Verification: https://twitter.com/FredHiebert/status/248608666096381953. Ask me anything.
