Through the application of radiometric dating techniques, the relative and absolute ages of rocks and fossil records offer proof of the earth's geographic past.

The geologists' dating techniques are typically based on radioactive dating.

To date the history of such events, credible sources of information such as the natural decay of the elements or compounds contained in the artifacts are used.

For instance, Red Rock Canyon is a region of geologic significance to all people.

The Red Rock Canyon National Conservation area is a beauty that took millions of years to create. Red Rock Canyon was discovered at the bottom of an ocean basin around 500 million years ago.

This ocean basin has accumulated limestone that is home to marine life fossils. The Aztec Sandstone has been found to contain the footprints of two-footed, meat-eating dinosaurs.

There were also uncovered the footprints of small creatures including spiders, scorpions, early mammals, and proto-mammals. Red Rock Canyon's fossils and rock formations provide proof of the planet's geologic past.
