2007 Grand Canyon History Symposium Brad Dimock Dimock was born in Ithaca, New York, and earned a Bachelor of Arts from Prescott College in central Arizona. He proceeded to squander his education for more than twenty-five years as a commercial boatman in Grand Canyon and the rivers of Utah, Alaska, Mexico, Guatemala, Chile, Ethiopia, and Tanzania. He is now a writer, river guide, and aspiring hermit living in Flagstaff, Arizona. He has written for numerous magazines and has stories in several anthologies. He was one of three authors that collaborated on The Doing of the Thing; the Brief, Brilliant Whitewater Career of Buzz Holmstrom, which won the National Outdoor Book Award in 1998. His profusely illustrated book, Sunk Without a Sound, The Tragic Colorado River Honeymoon of Glen and Bessie Hyde, details the search and the findings in a riveting, often humorous style. Winner of the National Outdoor Book Award and the Arizona Highways Nonfiction Book Award. Dimock worked with White's granddaughter on a book in support of White's voyage (Hell or High Water: James White's Disputed Passage Through Grand Canyon, 1867, 2001 Utah State University Press), and has done quite a bit of independent research on the controversy. Presentation Abstracts... The Mysterious Hum Woolley:   In 1951 researcher P. T. Reilly met a man named Arthur Sanger, who told him of his river trip through Grand Canyon in 1903. Until then, Sanger's voyage had gone unrecorded. Reilly researched extensively and began to piece together the expedition, headed by a 60-year old gentleman named Elias Benjamin "Hum" Woolley. Another historian, the renowned Otis "Dock" Marston joined the search, amassing large files on each of the three trip participants. Yet other than an article in a 1962 Desert Magazine, and ten short paragraphs in David Lavender's 1985 River Runners of Grand Canyon, Hum Woolley's exploits remain obscure and poorly understood. For this presentation, Dimock proposes to expand on a short talk he gave to Grand Canyon River guides in Spring 2006, synthesizing much more material than he had at that time, adding more detail on the trip participants, and including more context and analysis of their voyage. Dimock would also like to explore the possible influences that led to their trip, as well as any influence—or lack thereof-they may have had on posterity. In short, he plans to do the "Complete Hum Woolley." James White Did Float Through Grand Canyon in 1867:   Dimock will present a counterpoint argument to Tom Myers' presentation supporting the likelihood of James White making a successful traverse.
