There was a time in the geologic past when Washington and Oregon didn’t exist and an ocean flooded inland across Idaho. Many of the rocks that make up the Boulder, Pioneer, Smoky, and White Cloud Mountains were formed in this oceanic setting.
Join Dr. Paul Link of Idaho State University for a morning lecture and afternoon roadside field trip where you’ll learn the remarkable story of how this ocean formed and how rock that amassed below sea level became the highly elevated land that surrounds us today.
