Ellensburg Vantage Highway Corridor Field Trip

The Ellensburg Chapter of the Ice Age Floods Institute will host a field trip that covers the Vantage Highway corridor between Ellensburg and Vantage on Saturday 18 May 2024.

We will meet at Wildhorse Wind and Solar Facility and Renewable Energy Center parking lot at 11:00am on the 18th.

The trip will include stops at:
1) Renewable Energy Center for a big picture view of geology and physical geography of the area;
2) Pumphouse Road to see impacts of past and current erosion (including that from the 2022 Vantage Highway Fire);
3) Ginkgo State Park Trees of Stone Interpretive Trail for ancient Ginkgo trees and the upper limit of Ice Age flooding in the area; and
4) Ginkgo State Park Interpretive Center for a more complete view of the petrified forest plus  impacts of Ice Age flooding along the present-day Columbia River channel.

Given that we will be field tripping on the 44^th anniversary of the 1980 eruption of Mt. St. Helens, that story will also be woven into several field trip stops.  And if the weather stays somewhat cool and wet into May, we should see plenty of wildflowers in the shrub steppe.

We will have several short (<0.5 mile) hikes on this trip.  Make sure to wear sturdy hiking shoes or boots, dress for the weather, and bring plenty of drinks.

As on past Ellensburg IAFI trips, this is an automobile trip.  We will provide a hardcopy field guide for the trip at Stop 1.  I will also send out a pdf of the field guide several days before the trip.  If you have questions, feel free to contact Karl Lillquist at lillquis@cwu.edu.

Hope you can join us!
