The Complete Guide to Petrified Wood: Madagascar, Pacific Northwest & Beyond
Growing up in rural Oregon, I’ve been surrounded by petrified wood my entire life. The Pacific Northwest—where ancient forests once stood and where specimens are still discovered today—has given me a lifelong fascination with these remarkable natural treasures. Petrified wood isn’t just a product I sell; it’s a passion that runs deep in my roots.
At Putnam Valley Trading Co., I’m honored to share petrified wood from around the world with collectors and home decorators alike. Each piece tells a story of transformation, preservation, and the incredible artistry of natural processes.
Let me share what makes petrified wood so extraordinary—and why specimens from different regions of the world each have their own unique character.
What Exactly is Petrified Wood?
Petrified wood is fossilized wood where the organic material has been replaced by minerals—primarily silica (quartz), but also including calcite, pyrite, and opal. Through a remarkable geological process called permineralization, ancient wood is transformed into stone while often preserving the original structure, including growth rings, bark texture, and even cellular details.
The word “petrified” comes from the Greek word petro, meaning “rock” or “stone.” And that’s exactly what happens: wood literally turns to stone.
What makes this transformation so special? Unlike ordinary fossilization where organic material simply decays and leaves an impression, petrification actually replaces the wood’s structure molecule by molecule with minerals. The result is a stone replica that captures every detail of the original tree.

How Does Wood Become Stone?
The petrification process requires very specific conditions:
Rapid Burial: Trees must be quickly buried by sediment—volcanic ash, mud, or sand—before they can decay. This cuts off oxygen and slows decomposition.
Mineral-Rich Water: Groundwater carrying dissolved minerals (primarily silica) must flow through the buried wood.
Mineral Replacement: The minerals gradually infiltrate the wood’s cellular structure, replacing the organic material cell by cell while maintaining the wood’s original form.
Crystallization: Over vast stretches of time, these minerals crystallize, transforming the wood into stone while preserving intricate details like growth rings and bark patterns.
Geological Uplift: Eventually, erosion and geological forces expose these fossilized trees, allowing us to discover and appreciate them today.
The colors you see in petrified wood—vibrant reds, deep browns, golden yellows, brilliant oranges, and even blues and greens—come from different trace minerals present during formation. Iron oxides create reds and oranges, manganese produces blacks and purples, and copper can create greens and blues.
Petrified Wood from Around the World
One of the most fascinating aspects of petrified wood is how specimens from different regions have distinctly different characteristics. Let me share some of the most remarkable sources:
