Gear Reviewer Cameron Smith's archaeological, mountaineering, sailing, and icecap expeditions have taken him to Ecuador, Colombia, Africa, Canada, Alaska, and Iceland. In 1998 he built a 60-foot, 20-ton replica of a Native Ecuadorean sailing raft and sailed it from Ecuador to Panama with the international Manteno Expedition (www.balsaraft.com). From 2000-2004, Cameron was the sole field member of the SoloIce Expeditions, in which he finally made a solo, winter ski crossing of Iceland's Vatnajokull ice cap in 2004. Dr. Smith is a Fellow of the Royal Geographical Society, a Fellow of the Explorers Club, a member of the Authors Guild, and a member of the Society for Human Performance in Extreme Environments. He teaches a variety of field and classroom courses in prehistory at Portland State University's Department of Anthropology. His expeditions have been televised on the Outdoor Life Network ('Voyage of the Manteno', 2000), and National Geographic Television ('The Deadly Glacier', 2005). His non-technical writing has appeared in Scientific American MIND, Archaeology, Skeptical Inquirer, South American Explorer, The Next Step, Spaceflight, Playboy, and many other magazines. He is currently completing, "The Frost Giants", his book on the SoloIce expeditions, and engaged in a three-winter expedition to the sea ice of North Alaska: walking the terrain in 2007, paragliding over it in 2008, and diving under it in 2009 (www.soloice.com). He is also beginning an underwater survey of the Ridgefield Wildlife Refuge in Washington state, to complement his excavations on land there since 1992. His blog, Amphibian Adventures (http://amphibianadventures.blogspot.com/), covers his outdoor experiences. Cameron joins us from the US.
