Petrified Forest, Arizona
Millions of years ago this high, dry grassland was a vast floodplain. Tall trees once grew along the banks. These trees fell and swollen streams washed them into adjacent floodplains. A mix of silt, mud, and volcanic ash buried the logs cutting off oxygen and slowed the logs decay. Silica-laden groundwater seeped through the logs and replaced the original wood tissues with silica deposits eventually crystalling them into quartz. Thus the logs were preserved as petrified wood.

This photo and others to follow were taken while we were in Arizonz escaping the snow and cold of Alberta. We were in awe of what we saw and the beauty of this area was at times overwhelming.
Hope you enjoy the photos.
As always thank you for visiting my photo site and for your comments.
