Studying nature is a great way to feel young…comparatively speaking, that is. There are trees that are hundreds of years old as well as turtle and bird species that can easily outlive the humans who care for them. The entire human race is like a newborn when compared to billion-year-old rocks. It’s mind blowing!

Thanks to a generous gift from the Franke family, we’ve created a way to explore this concept of time through nature. We’re proud to introduce a new treasure, a 3 Billion Year Walk through the Milwaukee Rotary Centennial Arboretum.
