petrified forests
Crystallized ancient woodlands
Petrified forests are areas where ancient trees have been preserved through mineralization—organic material replaced by stone over millions of years.
The wood retains its original structure but becomes rock, often beautifully colored by minerals.
The Petrified Forest in Arizona contains logs over 200 million years old.
The term can also describe any landscape of standing dead trees, though the geological sense dominates.
