What Is Arizona Petrified Wood
Petrified wood is a unique natural phenomenon when organic wood turns into stone through petrification. It occurs when trees or plants are buried by sediment or volcanic ash, which protects them from decay and keeps them from breaking down.
Over time, groundwater minerals like silica, calcium carbonate, and iron oxides seep into the porous wood cells and replace the organic matter. As the wood breaks down, the minerals slowly form crystals and harden. This keeps the wood’s original structure and cellular patterns in stone.
Arizona’s unique geology and mineral-rich groundwater have contributed to the formation of petrified wood with vibrant colors and intricate patterns.

The types of petrified wood found in Arizona
Arizona has different kinds of petrified wood, each with its traits. Here are some types of petrified wood found in the state.
Agatized petrified wood
Agatized petrified wood is a special kind of petrified wood in which the wood has been replaced by agate, a type of microcrystalline quartz. It’s a beautiful type of petrified wood that is highly valued because it looks like glass and has intricate patterns and colors from the replacement process.
Agatized petrified wood starts to form when dead trees or branches are buried under sediment or volcanic ash layers. This cuts off their access to oxygen and slows down the decomposition process.
Over time, silica-rich groundwater seeps into the buried wood. The water with lots of silica seeps into the wood cells and spreads through the organic matter, slowly replacing it with quartz.
Blue forest petrified wood
Blue Forest petrified wood, also called Blue Forest Stone, is unique in some places, especially in northeastern Arizona. It has a unique bluish-gray color and often has complex patterns and dendrites made of manganese and other minerals.
As the wood breaks down and rots, the minerals in the groundwater are deposited in the cellular structure of the wood. Manganese oxides, in particular, make dendritic patterns that look like delicate ferns or tree shapes. As the manganese becomes minerals and grows in the wood, it makes these dendrites.
The unique bluish-gray color of Blue Forest petrified wood is often attributed to the presence of iron minerals, such as iron oxides, which can give a blue color when combined with manganese dendrites.
Jasperized petrified wood
Jasperized petrified wood is a special kind of petrified wood in which the wood has been replaced by jasper, a type of microcrystalline quartz. Its rich red and brown colors make it look like jasper, where it gets its name.
It’s made in the same way that other types of petrified wood are. It starts with trees or plant parts being buried under layers of sediment or ash from a volcano. Over time, the wood sinks into groundwater with a lot of minerals, like silica.
The mineral-rich water enters the wood cells, slowly replacing the organic matter with quartz. In the case of jasperized petrified wood, jasper, opaque, fine-grained quartz is the replacement mineral.
Rainbow petrified wood
Rainbow petrified wood is a type of petrified wood that is beautiful and highly valued because of its bright colors. It’s made through a process called permineralization. In this process, the original wood is replaced by a mix of minerals, giving the stone a beautiful range of colors.
The bright colors in rainbow petrified wood come from certain minerals and how they interact with the cellular structure of the wood. Iron oxides, for example, can make red, orange, and yellow tones, while copper can add blue and green tones.
The swirls and patterns in rainbow petrified wood are caused by the minerals that enter the wood’s growth rings and cell structure.

General Areas You Should Try
Because Arizona is so big, we want to ensure your search works. It’s essential to look for the key and focus on places where petrified wood is often found.
Desert Regions
Desert areas are great places for collectors to look for petrified wood for several reasons. The dry climate of deserts helps keep living things alive for a long time. With little rain and low humidity, dead trees and plants don’t break down as quickly, which allows the petrification process to work better.
Geological structures in deserts often make it easy for petrified wood to form and stay in place. Ancient river systems, floodplains, and volcanic activity all help deposit sediments, which cover timber and start turning it into stone.
Petrified Forests
Because of many things, petrified forests are great places for collectors to find petrified wood. Petrified forests are places where old trees were kept and turned into stone over millions of years.
There is a lot of petrified wood in petrified forests, making it easier for collectors to find pieces. These forests often have many fallen logs, tree stumps, and small amounts of wood. This gives collectors a wide range of sizes, shapes, and colors.
Streams and creeks
These bodies of water act as natural channels that can move and show off pieces and specimens of petrified wood. With the help of erosion and weathering, moving water can break petrified wood loose from rocks or sediment nearby and carry it downstream.
Petrified wood that was buried or partially covered can be found and seen because water is always moving. As streams and creeks cut through layers of sediment, they expose new surfaces. This gives collectors the chance to find petrified wood that was hidden under the surface.
