During the Eocene, about 50 million years ago, the western coast of Washington State could best be described as:
O A. Cold, covered by periodic glacial ice, and marked by periodic (and catastrophic) floods.
O B. Beginning where Spokane is today.
O C. Swampy, warm, with tropical vegetation.
O D. Mountainous, dry, with vast forests and large megafauna.
O E. Arid, dry, desert-like, with vast areas of basalt flow.
