Season 01  Episode 21

It was the past that brought Dave Varricchio to present-day Montana. Over the past 20 years, paleontology work in Big Sky Country’s wilderness has provided him with unique insight into the Montana of 75 million years ago. While focused mainly on changes in the Earth's crust over the course of millennia, Dave also observes more rapid changes in the evolution of this once sleepy college town.
