Geologic Sightseeing
The Oregon landscape has been shaped by plate tectonics and millions of years of volcanic activity. Visitors who travel through the state will find many opportunities to examine the scenic geology and see and collect samples of minerals, rocks, and fossils. Oregon can be divided into the following 9 geologic provinces, each with outstanding geologic scenery.
