A little known episode in American mountaineering, is the attempt in the 1960s to plant a plutonium powered listening device on top of Nanda Devi. The CIA enticed a bunch of prominent mountaineers to become trained as spies, and to place this device in the Himalayas so that it might pick up information about China's nuclear tests. I have read Takeda's very good AN EYE AT THE TOP OF THE WORLD, and intend to get a copy of Kohli's SPIES IN THE HIMALAYAS.
