Four years after the first Yukon Geoscience Planning Workshop (the Marsh Lake Workshop, Yukon Geoscience - A Blueprint for the Future, Yukon Geology Program, March, 1995), forty-two representatives of industry, academia, and government met at the High Country Inn in Whitehorse to re-examine the state of Yukon geoscience. Over two days, with the expert facilitation of Steve Morison, Gartner Lee Ltd., the participants reviewed the first plan, the work that was done since 1995, and produced a new set of priorities to guide Yukon geoscience into the next millenium. The 1999 Yukon Geoscience Planning Workshop had a format similar to the 1995 workshop and many of the original participants were able to attend. This continuity greatly added to the quality and credibility of the input.
