Deep Time Walk


Join Boulder County Volunteer Naturalists for a ‘journey’ where we walk the 4.6-billion-year age of the Earth in 3 miles. In this “Deep Time Walk”, each step walked corresponds to 1 million years, therefore, the whole human history from Homo Sapiens to now happens in the last few inches! The Deep Time Walk enables people to learn from and connect to their own short-lived experience of time on Earth with the vast expanse of geological time right here in Boulder County. Open to adults and children 12 and older accompanied by an adult.

Registration for most programs begins on the 20th of the month before the event.

Registration required.


Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you'll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
