| Since 1967 when I took my first photographs of tracks, many individuals have shared in field experiences and helped gather the knowledge contained in this book. Others have loaned me their photographs, collections, or notes or in some other way contributed to my knowledge of tracking. I wish to express my thanks to my colleagues and companions: Dave Armstrong, Nancy Auerbach, Steve Bissell, Norm Bishop, Scot Burns, Denise Casey, Tim Clark, Willie Cunningham, Scot Elias, Bill Ervin, Louise (Richardson) Forest, Rusty Fuller, Howard Hash, Bob Hasenyager, Larry Higby, Tass Kelso, Kathy Ingraham, Nan Lederer, Chris Linville, Larry Marlow, Carron Meaney, Anna Moscichi, Dave Nead, Rick Richards, Bob Rozinski, Dave Slovisky, Roger Smith, Jay Stravers, Bruce Thompson, Betsy Webb, Olwen Williams, and Kathleen Zinnel. If I have missed thanking anyone, please accept my apologies. |
| I wish to thank John Emerick for his encouragement in the initial stages of producing this book. Margaret Murie also was instrumental in her understanding encouragement. Drawings were made of the foot from the otter skeleton associated by George Northrup. Wendy Stout drafted the gait patterns and scat graphs. Tom Schenck of Camren, Inc., took the color photographs of the scat. |
| Special thanks go to Claire Sward and George Brown for my early field days. Much of my early tracking experience was sharpened by lectures prepared and given as part of the National Outdoor Leadership School instructor training program; thanks to Paul Petzoldt. While a hunting guide and game processor in Wyoming, I received many opportunities to work with mammals and their sign; thanks to Win Condict and John Dunlap. I wish to thank all the students who have shared experiences with me while at the Aspen Center for Environmental Studies, Teton Science School, the Yellowstone Institute, and at other special courses. Many of my photographs were obtained while working for the Colorado Division of Wildlife and in Canyonlands National Park. I thank Dave Armstrong and Steve Bissell for these opportunities. During special tracking classes I gave for the Colorado Division of Wildlife and Yellowstone National Park naturalists, I benefitted from interactions with many individuals, including Norm Bishop, Chuck Loeffler, and Tom Lytle. Teton Science School supported the effort necessary to prepare the final manuscript by providing housing, working space, and access to the Murie Museum. I would like to thank Jeff Hardesty and Greg Zeigler for their help and support. The Denver Museum of Natural History and the University of Colorado Museum provided valuable access to reference collections. |
