Additional Details ------------------------------ Product description: To find out what really does lie beneath our feet, scientists from Denver's Museum of Nature and Science dug a 2,256 foot well in 1999 and what they found was a surprisingly drastic array of landscapes and animal life-it the very same spot. In addition to what they found in the sediment at that site, geologists were able to look at other findings in the area to pull together an amazing assessment of the geological history of Denver's Front Range.
