A Walk Through Time

A Joint Project By:

Broomfield Students
City of Broomfield
Geological Society of America

Virtual Tour
Each geologic section of A Walk Through Time contains a boulder that was formed during a specific geologic period as well as a descriptive plaque. The plaque is illustrated with a hand drawn picture of a creature that lived during the geologic period, a description of the geologic scene of the time, and a description of the boulder. The sundial, prehistory, and history sections contain descriptive plaques. All work - drawing and text - was done by students at Broomfield Heights Middle School.
