Walk a million years on this timeline trail.
To humans, a million years seems unimaginably long, more than 10,000 lifetimes. This trail helps you shift from human time to geologic time.
Find your birthday:
As you walk the trail, think of al that happened before your time.
Talk about time as you walk the trail:
Years -- your birthday
Decades -- your generation
Centuries -- US history
Millennia -- ancient peoples
10,000s -- changing climate
100,000s -- earthquakes and volcanoes
Millions -- a six million year old Grand Canyon
Billions -- oldest rocks in Grand Canyon |
