Found in the vicinity of Eden Valley, Wyoming, blue forest is typically smaller than average petrified woods. A good, general limb size may be about three to four inches in diameter; some up to more than a foot in diameter; others as little as half an inch or less. Incredibly, it dates to about 50 million years ago! Known for its rich blues , you will typically find that greens and blacks are also equally common. Regardless of color, blue forest petrified wood is often characterized by vivid tree rings and insect boring or heavily agatized areas and other interesting attributes that make this petrified wood one of the most cherished in the world. How did the Blue Forest come to be? While we arent scientists, there is plentiful information about blue forest petrified wood for us to draw upon. Around 50 million years ago (during the Eocene Epoch) forests of trees in Eden Valley and the Green River area of Wyoming most likely encountered volcanic explosions or similar activity that downed trees, with the trees eventually becoming submerged in water. Over time, an algae would encase the trees completely, the beginning of the first stages of petrification. This was a slow process that replaced the dead organic material from the tree with quartz, silica, agate, and other minerals. Once the mineral-filled water had entirely replaced the branches, the limbs, and even whole tree sections, intricate details like tree rings or insect boring were permanently preserved. The origins of the various colors are directly related to the types of minerals that were present during this process.
