GEM MORRISON, CIRCLE CLIFFS PETRIFIED, HENRY MTN WOODS

Some of the most coveted, colorful, rare and sought after
of all the petrified woods

Over 135 million years ago, the Grand Staircase Escalante National Monument, was closer to the equator and tropical. Dinosaurs roamed the area. The plant life consisted mostly of cycads, ferns and conifers. The earth was geologically unstable. Floods and erosion would uproot trees and plants depositing them in flood plains and along sand bars. Later, volcanic ash covered the area.

In order for the trees to petrify, they had to be buried quickly with mud and silt to eliminate oxygen which would cause them to deteriorate. Ground water rich in silicon dioxide and other chemicals would saturate the buried trees. The reds, browns and yellows result primarily from compounds of iron, while manganese and other minerals account for the purples and dark blues. Through a mineralization process on the cellular level, and by silicon dioxide acting as a cementing agent, the wood became petrified. This process took millions of years!

This area lies within the Colorado Plateau, which has been uplifting for about 40 million years. These upheavals of the earths crust break the logs into irregular sections and exposes them to the forces of erosion. After being exposed the logs are further cracked and broken by the effects of freezing and thawing water that seeps into the cracks.
