November 2–5, 2003 Greetings! Washington State Multifaceted Seattle provides a fascinating arena for the GSA Annual Meeting. Seattle Convention & Trade is an amazing place—aesthetically, culturally, and geologically. In few other North American cities do Holocene lahars lap up against the downtown shopping district, Center, Seattle active surface faults bisect half-billion-dollar sports stadiums, glacial fjords float ten thousand commuters daily to their -controlled office buildings, and recent the size of small New England townships provide home to million-dollar ANNUAL MEETING SPONSOR views for software executives and coffee moguls. If you’ve never been to Seattle, come to experience a place, for better or worse, like none other. If you know the city like the back of your hand, revisit old friends and resample the local beverages. For the Title Sponsor of the 2003 GSA Annual Meeting rest of you, enjoy the continuing evolution of one of the most unique cities, and set- tings, of our continent. 2003 ANNUAL MEETING HOST Geoscience Horizons: Seattle 2003 promises to be an exciting meeting. There’s a great set of field trips and workshops, technical sessions, and the opportunity to University of Washington make or renew collegial connections. The meeting has a broad range of sessions that both encompass and expand the boundaries of traditional “geologic” studies. So, ex- amine the session titles, find your niche, and offer your contribution by submitting 2003 ANNUAL MEETING an abstract. If you don’t find your topic area, please submit to one of the general ses- sions—your session-mates may be the most eclectic, creative group at the meet- LOCAL COMMITTEE ing.
