After he joined the UO faculty, he continued to lead hundreds of geological field trips throughout the state. He studied Oregon's geological record of the Tertiary period deeply. During those 65 million years, the dinosaurs disappeared, grasslands expanded, and grazing animals and other mammals, birds, bony fish and flowering plants took over the world. The Tertiary period ended about 2 million years ago, just before the Ice Ages began. Located on the UO campus near the corner of East 15th and Agate, the Museum of Natural History and museum store are open from noon to 5 p.m. Tuesday through Sunday.
Free parking is available in front of the museum with a permit from the front desk.
