I've done public presentations about my expeditions and excavations in many venues, including Portland State University, local high schools, NIKE, Patagonia, and the Oregon Museum of Science and Industry. My presentations run about 45 minutes to an hour, excluding time for questions, and include many images and multimedia. Currently developed presentations include To Save the Polar Bear: The Native Perspective, A Hundred Thousand Years of Symbolism: The Revolution of 'Cognitive Archaeology', Through the Mist: Alone in Winter Across Iceland's Vatnajokull Ice Cap and Seven Hundred Miles on a Primitive Raft.
