Specially photographed they are shown in their entirety and in magnificent details. Petrified wood is formed from fallen trees that in the absence of oxygen and microbes, and with water containing minerals, through a replacement process called permineralization, slowly transform into visually spectacular fossils. But Nature often uses a paintbrush in its preservation magic, splashing the wooden canvas with an array of colours and hues before fixing it in a matrix of hard durable quartz, thereby creating splendid works of art. Petrified wood has been found throughout the world, but actual petrified forests are truly noteworthy in the United States, the most famous being the Chinle Formation forest of Arizona.
