This beautifully preserved petrified log
is made up of almost solid quartz, and its unexpected bright colors sparkle in the sunlight.
Located in hills with ravines hollowed out by nature, the forest is made of petrified logs
that indicate trees were there that were more than 100 feet tall and older than a thousand years.
Fossil termite nests in petrified logs
, leaf impressions with evidence of insect chewing, or predator bite marks in ancient bones demonstrate interactions between organisms of the past.
A vast forest of petrified logs
, strewn across what is now a desert, and fantastic life forms locked in stone bespeak a time when tropical streams and nearby swamps were home to giant 200-pound amphibians, enormous crocodile-like beasts called phytosaurs, and the earliest dinosaurs.
Also, the thick layer of sediment atop the ash contained charred, petrified logs
up to 3 feet thick, which had burned in the fire and fell later.
Later, the area was uplifted by forces of nature, cracking the petrified logs
as neatly as if someone had sawed them.
