200 feet, 15.6 million years

A town in which science is on display in the mass transit system is the perfect place for an NSTA conference. In Portland’s only underground station (70 meters under ground), there is a 200-foot long core sample contained in a glass tube, representing 15.6 million years of geological activity. Click on the picture above to see more of the core sample and the accompanying exhibit information, as well as some images from the Hoyt Arboretum above. Better yet, hop on a MAX blue or red line train and head west.
