Converging at Cascadia

Boulder, Colo., USA: On 15-17 May 2019 more than 600 geoscientists from western North America and beyond will gather at the Oregon Convention Center in Portland, Oregon, USA. They meet to present new discoveries, expand on existing science, and explore geologic features of the Cordilleran region extending from the U.S. and Canadian west coast, north to Alaska and the Arctic, south to western Mexico, and even out to Hawai'i and the Pacific.

The scientific program will include more than 400 oral and poster presentations, organized into 22 themed and discipline sessions covering most research areas in the geosciences. Major topics embrace the rock-forming events, tectonics, and geologic history of the Cordillera, including the volcanoes and earthquakes that characterize much of the region; and the processes active at Earth's surface, including rivers, glaciers, landslides and other landscape elements. Sessions will be held covering geological education, sediments, fossils, geologic mapping, and earth resources. More than 200 students will attend this meeting, many of them presenting their work in a poster session dedicated to student research.

Seven pre- and post-meeting field trips will spread out to eastern Oregon, into the Columbia Gorge, up to Mount St. Helens, south to Willamette wine country (and points in between) to see and discuss regional rocks, features, and geologic problems (natural and human-related) on the ground.

During the conference, 15 commercial vendors, government agencies, and other geoscience organizations will host display booths in the exhibit hall.

Hosting institution: Portland State University

Selected Highlights of the Scientific Program

Four technical sessions were organized to recognize the contributions of six scientists to understanding the geology and resources of western North America:

D3. The Hydrology of Volcanic Terranes: Celebrating the Scientific Curiosity of Ken Lite and Marshall Gannett
Wednesday, 15 May (talks and posters)

T1. Cordilleran Tectonics from the Basin and Range to Alaska and the Arctic: A Celebration of Elizabeth Miller's Career
Wednesday, 15 May (talks and posters)

T3. A Simple Twist of Plate: In Honor of the Career Contributions of the Dynamic Duo -- Rick Blakely and Ray Wells -- to Understanding Plate Interactions and Deformation in Cascadia
Wednesday, 15 May (talks and posters)

T2. Advances in Seismic Hazard Assessment through Paleoseismic and Tectonic Geomorphic Fault Studies: In Honor of Ray J. Weldon II, for His Career and Contributions to the Field
Thursday, 16 May (talks and posters)

Among hundreds of other presentations, many topics that might be of general interest to press and public include the effects of the Missoula Floods across Washington and Oregon; changes in glaciers in the North American West; volcanic processes in the Cascade Range; mapping and risk assessment for geologic hazards; research and practice in geoscience education; and new discoveries of dinosaur fossils in Oregon.
