The word, “petrify” literally means, “turn to stone.” Petrified wood, then, is wood that has turned into stone.

How is it formed? The process of petrification, which can take million of years, starts with three ingredients: wood, water, and mud. When a tree falls, it gets covered with dirt, and after an event such as flood, sediment covers the tree. As the tree rots, the soft spot between the trunk rings rot away and water fills the void and bring in various kinds of mineral deposits, also known as “permineralization.” If you look closely, you can see the rings and pores preserved from the original tree.

We had a chance to visit a Rock Store in Holbrook, Arizona, and saw tons of polished petrified wood that was made into coffee table. Prices range from $1,000 and up. To give you an idea of what the finished products look like, please visit this site.

I took these pictures of petrified wood, by the way, at the Rock Art Ranch.
