The Deep Time Walk is a 4.6km walking audio history of life. This unfolding takes you from 4.6bn years ago to the present day, with each metre representing one million years. As you walk you begin to recognise the long geological processes and self-regulating patterns that have produced the conditions for the evolution of life. The Deep Time Walk App is a ground-breaking new project, which enables anyone, anywhere to experience a walking audio history of the living Earth. We have assembled a broad and experienced team to produce it.
