Petrified Forest

The trees are so scared that they hide under the rocks!

This is some petrified wood. Fallen trees were covered in volcanic ash, from which silica would leech into the wood and make crystals. Other substances would also combine with the silica to make all the pretty colours.

There are also a lot of fossils in the petrified forest which were preserved in volcanic ash.
