Monday Geology Picture(s): Petrified Trees
Posted by Evelyn Mervine
My friend Ray recently visited Petrified Forest National Park in Arizona and was kind enough to send me some of his gorgeous pictures of the landscape, including the petrified trees. Ray says that these pictures were all taken along the Blue Mesa Loop. These fossilized trees are about 225 million years old! They are weathering out of the Chinle Formation, a beautiful Triassic sedimentary unit. I’ve never visited this park, but it’s now very high on my list of geological places I’d like to visit!
Thanks for sharing some pictures here on Georneys, Ray!
Nice! Ooooh–beautiful scour-and-fill structure in photo #2!
