The one-mile-long Walk Through Time you are about to take unfolds a scientific understanding of the five-billion year evolution of life on Earth. The Walk progresses from the formation of the solar system to the present. The Walk offers a rich context for exploring fundamental issues regarding humanity and the future of all life on Earth.
Scale: Each foot of the Walk represents one million years. At this scale ... 1 foot = typical time for continents to move and earthquake faults to slip 20 miles; 0.1 inch = time span back to the end of the last Ice Age; 0.001 inch = human lifetime
