Doug Peacock AKA George Washington Hayduke

 Doug Peacock is an American naturalist, outdoorsman, and author. He is best known for his book Grizzly Years: In Search of the American Wilderness, a memoir of his experiences in the 1970s and 1980s, much of which was spent alone in the wilderness of the western United States observing grizzly bears. 

Doug Peacock was born in Alma, Michigan, and attended the University of Michigan. He served as a Green Beret combat medic during the Vietnam War and, upon returning, felt so disillusioned with human society that he sought solace in the beauty of the wilderness. Although he had little scientific background, his passion for and firsthand experience with bears soon brought him recognition as an expert in grizzly behavior. He was a friend of author Edward Abbey, and served as the model for the character George Hayduke in Abbey's famous novel The Monkey Wrench Gang.
Peacock's 2005 book, Walking it Off: A Veteran's Chronicle of War And Wilderness, continues his memoirs, in the wake of Ed Abbey's death. He ventured into the southwest deserts to walk off the scars left by his friend's death. In the process, he revisited Vietnam in flashbacks, remembering the cantankerous friendship with Abbey, and almost died in his journey to recover from "this terminal disease called life" in Nepal with his friends Alan Burgess and Dennis Sizemore.
Peacock is also friend of American author Rick Bass. In Bass's book "The Lost Grizzlies: A Search for Survivors in the Wilderness of Colorado" Peacock is a key element in the search for evidence that there are still grizzlies in the San Juan Mountains.
Peacock was a 2007 Guggenheim fellow, and currently lives in Montana with his wife Andrea, author of Libby, Montana: Asbestos and the Deadly Silence of an American Corporation. Peacock speaks in schools about wilderness, conservation, and the need to preserve our wilderness. Doug is the chairman of the board of trustees for Round River Conservation Studies.
