Arizona - Petrified Forest National Park

Petrified Forest national Park
Arizona
The brilliant colors in the petrified wood come mainly from quartz, manganese and iron.  Most of the fossilized logs are from a tree called Araucarioxylon arizonicum, while two others, Woodworthia and Schilderia, occur in small quantities in the Northern part of the park.  All 3 species are now extinct.
