Jerry Bryant gave a talk last night on area geography to a full house. We had room for 20 and there were 40 requests. He covered the geology of this area, pointing out marks in the rocks that most of us would never notice. He discussed the volcanic activity from over a million years ago and the most recent period about 32,000 years ago. Standing outside the Park office it was easy to pick out most of the things he had spoken of, especially the different, and inverted, layers of volcanic basalt.
