- Description:
- Postcard view of a boy standing on a giant piece of petrified wood in Petrified Forest National Monument near Holbrook, Arizona. Back of card: PETRIFIED FOREST NATIONAL MONUMENT, ARIZONA is located east of Holbrook between U. S. 260 and 66. The logs were buried 160 million years ago by sediments composed principally of volcanic ash. Slowly the wood of the logs was impregnated with mineral solutions of silica which gradually filled in the wood cells until the logs are now 98 percent stone and 2 percent wood.
