Walk Through Time
The 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: In real life the physical Walk is presented over the length of one mile (1.6 Kilometers). At this scale, each foot (.305 meter) of the Walk represents one million years of time. At this scale ...

1 foot (.305 meter)=typical time for continents to move and earthquake faults to slip 20 miles
0.1 inch (.254 centimeters)=time span back to the end of the last Ice Age
0.001 inch (.025 millimeters)=human lifetime

The timeline at the top of this page measures 5,280 pixels in length and was created to show the scale of the real Walk (1 mile = 5,280 feet).
