"Volcanoes to Vineyards"

From accreted terranes to viticulture terroir, this year’s trips will emphasize the “Volcanoes to Vineyards” theme of the meeting, but also cover a range of Pacific Northwest geoscience topics and geoscientist hangouts. Learn how tectonism, volcanism, stupendous flood basalts, cataclysmic flooding, and landslides have shaped the Northwest and now influence hazards, resources, and human habitation. Remarkable scenery, whitewater boating, and brew pubs and wineries are requisite elements of the Northwest experience and will to be integral to several trips.

All trips begin and end at the Oregon Convention Center in Portland unless otherwise indicated. Trip fees include transportation during the trip; other services, such as meals and lodging, are noted by the following abbreviations: B—breakfast; L—lunch; R—refreshments; D—dinner; ON—overnight lodging.
