Our next stop on the trip was at the Pacific Coast  cranberry research foundation. Here we looked at how cranberries were harvested and researched, as well as a geomorphologic overview of the area. We then traveled to a place called Port of Peninsula in Willapa Bay. Here, over lunch, our field trip leaders discussed how vibracores of the ground here were used to show evidence of previous earthquakes.

Following lunch, we headed off to Joe Johns Road. Here we looked at a long Ground Penetrating Radar profile of the area to locate scarps that were formed due to seismic activity. The dates of the earthquakes were backed up by the use of optical and radioactive carbon dating.
