By Dr. Keith Jackson - Geology PhD


Petrified wood is truly an astonishing sight to behold. Imagine a tree that has been transformed into stone over millions of years, with every detail preserved in a mix of sparkling, beautiful, and colorful minerals. Simply put, it’s a stunning relic of the past— each petrified tree an ancient story locked in stone.

However, finding petrified wood in Oregon can be challenging if you’re not familiar with the terrain and don’t know where to look. Our lush Pacific Northwest state is home to a variety of landscapes, from coastal regions to vast forests and high deserts, making it quite an adventure to find these hidden geological treasures.

But don’t worry! We’ve done some thorough exploring and found several great places to find Oregon petrified wood. Whether you’re an experienced fossil hunter or just getting started, you’ll have a chance to uncover these incredible remnants with our help through this complete guide.

What Is Oregon Petrified Wood

Petrified wood is a special kind of fossil, a wonderful surprise from nature that takes millions of years to create. It all starts when a tree gets buried by mud, ash, or other materials. This protects the tree from decay, setting the stage for a process known as permineralization.

In this process, groundwater rich in dissolved minerals seeps into the buried tree. Over time, these minerals replace the buried tree’s organic materials, turning it slowly into stone, with the original tree structure perfectly preserved in a rocky form.

But this amazing transformation doesn’t happen just anywhere. Petrified wood is often found in places that were once rich with trees and had conditions that could quickly bury them, like volcanic regions and river floodplains. In the United States, one such location is Oregon.

The Types of Petrified Wood Found in Oregon

Understanding what petrified wood is and how you can identify it deserves a discussion of its own, so we created an article on it that you can check out. And before you head out to find Oregon petrified wood, it would help a lot to know what types of this natural wonder you can come across here.

Petrified Fern

Petrified fern is a fascinating type of fossil that tells us about ancient, lush environments. It often shows the fern’s original leafy structure, veins, and even sporangia, the tiny structures where it makes its spores. Minerals have also replaced the plant’s tissues, and sometimes, they add vibrant colors to the petrified fern.

But how can you tell if you’ve found a petrified fern? Look for the distinct leaf patterns! Ferns have a unique, feathery look to their leaves, which often remain visible in the fossil.

Bogwood Agate

Bogwood agate, sometimes known as petrified bogwood, is another spectacular creation from nature. It forms when trees or woody plants fall into an ancient bog or swamp, get buried in the muck, and start to turn into stone. In this special setting, the wood can become “agatized” or replaced by agate.

This type is a wonderful combination of the natural beauty of wood and the sparkling allure of agate. But how can you tell it’s bogwood agate? The key is the mix of wood features and agate. You might see tree rings surrounded by bands of agate, a hint of the tree’s bark, or a quartz-filled knot where a branch once grew.

Opalized Petrified Wood

Opalized petrified wood is a captivating example of nature’s artistry, where the organic material of a tree has been replaced by opal. This gemstone often displays a dazzling array of colors when viewed from different angles. Imagine the texture of ancient wood combined with the shimmering beauty of opal— it’s breathtaking!

To tell if you’ve found opalized petrified wood, look for the structure of the original wood, like tree rings or bark texture, combined with the distinctive, often iridescent, shine of opal.

Silicified Wood

Silicified wood is another form of petrified wood that’s truly amazing. A piece of this can look a lot like the original wood, but it’s actually stone! The details of the tree, like the bark and tree rings, can be preserved in remarkable detail.

But instead of being made of wood, it’s made of silica, often in the form of quartz. It can have a sparkly, crystalline texture and may even show different colors depending on what other minerals were in the groundwater.

Chalcedony-lined Petrified Wood

Chalcedony-lined petrified wood is a striking type where the natural cavities and cracks within the wood have been filled with chalcedony. Its exterior can retain the texture and features of the original wood, such as the bark and tree rings. But if it’s broken open or cut and polished, you’ll see the stunning chalcedony inside.

To recognize a chalcedony-lined petrified wood, simply be attentive to the combination of wood-like features with the unique appearance of chalcedony, especially in the cavities or fractures of the piece.

General Areas You Should Try

If you’re planning to explore sites that cover wide bases, make sure you check out the following areas where petrified wood is usually found:

Streams and Creeks

Streams and creeks are prime spots for finding Oregon petrified wood. These waterways are natural transporters of rock and sediment. When rain falls on hills and mountains, it washes loose rocks and soil down into the streams. Among these rocks, you can often find pieces of petrified wood that have been eroded.

Petrified wood can be quite heavy, so it tends to get deposited in certain areas of a stream. Look for places where the water slows down, like the inside bend of a stream, or where larger rocks have piled up.

Rivers and River Banks

Rivers and river banks in Oregon can be gold mines when it comes to finding petrified wood. These places are like nature’s conveyor belts, carrying rocks, sediments, and petrified wood from upstream locations down to new areas.

As a keen-eyed rockhound, you can check areas where the river slows down, like sandbars, or where larger rocks collect. These are spots where heavier items, like petrified wood, are likely to settle. River banks can also be great hunting grounds, especially after a flood or high water event, when new material has been deposited.

Petrified Forests

Petrified forests are fantastic spots to seek out petrified wood. These unique areas represent ancient landscapes where trees were quickly buried by sediment or volcanic ash, then slowly turned to stone over millions of years.

In these preserved forests, petrified wood is formed. Each piece tells a story about the plants that lived in that ancient forest and the conditions they experienced.

Common Questions About Finding Petrified Wood In Oregon

Here are some of the most commonly-asked questions about finding petrified wood in Oregon that you might have in mind, too:

How old is Petrified Wood in Oregon

Oregon petrified wood provides a fascinating window into our ancient history, with many pieces dating back tens of millions of years.

Much of these come from the Miocene epoch, which lasted from about 23 to 5 million years ago. This was a time of significant geological activity in our region, with frequent volcanic eruptions that quickly buried local forests under layers of ash and sediment. Over long periods of time, this organic material was replaced by silica and other minerals, ultimately forming the beautiful petrified wood we find today.

So, when you’re holding a piece of Oregon petrified wood, you’re touching a relic from an incredibly distant past, a testament to the power and beauty of nature’s transformations.

Can you find Petrified Palm Wood in Oregon

Unfortunately, Oregon is not known for having petrified palm wood, as this type is generally associated with regions where palm trees naturally grew in the past. The petrified woods you’ll find here are mostly from coniferous trees due to our climate and environment when the petrification process occurred.
