Appendix A). This workshop was similar in nature to the previous five meetings, held in Lawrence, Kansas (Soller, ACKNOWLEDGMENTS 1997), in Champaign, Illinois (Soller, 1998a), in Madi- son, Wisconsin (Soller, 1999), in Lexington, Kentucky I thank the Utah Geological Survey (UGS) and their (Soller, 2000), and in Tuscaloosa, Alabama (Soller, 2001). Director and State Geologist, Rick Allis, for hosting this This yearʼs meeting was hosted by the Utah Geological meeting. In the tradition of past DMT meetings, it was Survey, from May 19 to 22, 2002, on the University of quite productive and enjoyable. I especially thank Grant Utah campus in Salt Lake City. As in the previous meet- Willis and Kent Brown (UGS), who coordinated the meet- ings, the objective was to foster informal discussion and ing, provided excellent support for the attendees, offered exchange of technical information. When an attendee an entertaining range of technical and social activities adopts or modifies a newly learned technique on the basis (e.g., a pre-meeting field demonstration of GPS-GIS of discussions at the workshop, the workshop clearly has tools), and managed the meetingʼs Web site (see Appendix met that objective. Evidence of learning and cooperation B). Thanks also to Cheryl Ostlund, Jo Lynn Campbell, among participating agencies continued to be a highlight and Mike Wright (UGS), Jan McEwan, Roni Whittle, of the DMT workshops (see example in Soller, 1998b, and and Ryan Halstenrud (Huntsman Cancer Institute), Lesle various papers in this volume).
