Taking a Walk Through Time
Imagine walking on a path where ancient creatures once lived--either in oceans or on landscapes
that have become the rock layers beneath your feet. As you walk along this path you can touch
some of the rocks from these layers--rockes that formed in an environment where a trilobite crawled,
where a giant Devonian fish died and was buried, or where a fierce-looking Triceratops and a
giant Tyrannosaurus Rex fought to the brutal end! As you take your Walk Through Time you will
begin to understand when these rocks came into being, under what conditions they formed, and what
creatures lived during the time that these rocks were formed.
Since geologic time measures the age of the Earth from its beginning as a planet to the present,
we have included in our Walk Through Time local prehistory by archaeologists and local history
by historians. On our scale, where the distance of one foot along the path represents one
million years, modern human activity covers a short time span, and would be represented by the
thickness of an adult human finger (about 1/2 inch) at the very end of your walk!
