A Walk Through Time - 4.6 Billion Years of Earth History in Half a Mile
Memorial Drive between Mass. Ave. and Wadsworth Street
The Earth is 4.6 billion years old, and many incredible events have occurred during its long and storied history; the formation of the oceans, the origin of life, the first animals, the rise and fall of dinosaurs, and the appearance and evolution of our own species, just to name a few. Take a half-mile walk along the Charles River between Massachusetts Avenue and Wadsworth Street as you explore a scaled-down version of the geologic timeline where each inch represents 145,000 years. Signs along the way will show you when some of these amazing changes and innovations have occurred throughout Earths history and will give you a new perspective on the immensity of geologic time. You will also learn about how geologists figure out how many millions or billions of years ago these events really took place, highlighting some of the important contributions from researchers at MIT.
