Making this journey offers an opportunity to do more than read about such changes. When you visit the John Day Fossil Beds National Monument
, nestled within the Journey Through Time's route, you'll be able to explore the very places where the drama is abundantly, though silently, still evident.
The 3-unit monument encompasses a region 40-50 million years old, the remnant of a subtropical jungle once dominated by massive volcanoes and huge brontotheres called "thunder beasts" which resembled modern rhinoceroses.
Four-tusked, elephant-like gomphotheres also roamed these hills and millions of years ago beardogs and entelodonts terrorized browsing animals in a forest landscape that was much warmer and wetter than today. Over 2,000 extinct fossilized species have been found in the valleys and canyons of the Journey Through Time region.
