New Mexico is huge and has many different types of geology. Finding petrified wood in the state can be tricky without the right direction. It’s easy to get lost or miss out on possible finds if you don’t have the correct information beforehand.
Plains cover the majority of our state mostly broken into two parts, the lava-capped uplands in the northeast and the Llano Estacado plains that is bounded roughly by I-40, the Pecos River, and Roswell to Hobbs. We also have the Northwestern plateaus and the southern deserts.
With so many different environments, finding petrified wood in Arizona can be really tough!
To find petrified wood, you need to know how to tell it apart from regular rocks and have some experience. This makes the hunt even harder. Even though it’s hard to find here, the rewards are fascinating!
What Is New Mexico Petrified Wood
Petrified wood is a fascinating natural phenomenon when minerals slowly replace the organic parts of old trees, turning them into stone. Most of the time, petrification takes millions of years and needs specific geological conditions.
It starts when a tree that has fallen or been buried is covered by sediment, like volcanic ash or river sediment, and can’t get oxygen. Without oxygen, decomposition happens more slowly, and minerals in the groundwater start to get into the wood’s cells.
You can look at our detailed guide on where to find petrified wood near you once you’ve visited all the places in our state. We are adding new state guides all the time.
The types of petrified wood found in New Mexico
Several kinds of petrified wood can be found in New Mexico, each with distinct characteristics. Here are some types of petrified wood found in the state.
Rainbow petrified wood
Rainbow petrified wood is a type of fossilized wood with a wide range of bright colors. The name “rainbow” comes from how it looks, bright and colorful like a rainbow.
Most of the mineral silica in rainbow petrified wood is in the form of quartz. As minerals replace the organic parts of the old tree during the petrification process, different impurities and trace elements can lead to a wide range of colors. These impurities and minerals react with the silica.
Coniferous petrified wood
Coniferous petrified wood comes from evergreen trees like pines, spruces, cedars, and firs. It’s a type of fossilized wood that has become stone through petrification. In this process, the tree’s organic matter is slowly replaced by minerals, turning the wood into stone.
This type of petrified wood forms when a tree falls or is buried in sediment, like ash from a volcano or sediment from a river. The water or groundwater seeps into the hole and covers the tree, cutting off oxygen. Without oxygen, the process of decay moves slower.
Fossilized palm wood
Palm petrified wood is fossilized wood from palm trees. It’s made in the same way that other types of petrified wood are. It starts when a palm tree falls or gets buried by sand or ash from a volcano or a river.
It can have different grain patterns and sometimes even keep the structure of the palm trunk, like how it looks like it’s made of fibers. These fossilized remains give us important information about ancient plants and help us learn about Earth’s history.

General Areas You Should Try
We want to ensure your search is successful because New Mexico is large. It’s crucial to search for the key and pay attention to locations where petrified wood is frequently found.
Petrified forests
Collectors looking for petrified wood treasures love to go to petrified forests. These old forests have been kept safe for millions of years and are full of fossils. These forests used to be full of tall trees, but now they are full of petrified wood.
Petrified forests often contain a variety of petrified wood types. Because of the many fallen trees and branches that turned into stone, collectors have much to choose from.
Streams and creeks
Streams and creeks are fantastic places for collectors to find petrified wood treasures. These flowing bodies of water offer unique opportunities for the discovery of fossilized wonders.
Streams and creeks help water get where it needs to go. As the water flows, the land around it slowly wears away, revealing treasures hidden in the sediments. This erosion process brings to the surface pieces or even whole pieces of petrified wood that were once buried below the surface.
Volcanic regions
Volcanic regions are fascinating and fruitful locations for collectors searching for petrified wood. These areas, shaped by volcanic activity, offer unique opportunities to discover remarkable fossilized wonders.
Most places with volcanoes have a lot of different minerals and elements. During the petrification process, these minerals get into the buried wood. This gives the petrified wood its bright colors and unique patterns. The fantastic beauty of the fossilized wood is partly due to its location in a volcanic area.
