4.7" Gary Green Jasper (Larsonite) Bog Wood Slab - Oregon

Gary Green Jasper, also referred to as petrified bog wood or Larsonite, is a form of petrified wood from a location near McDermitt, Oregon on the Nevada/Oregon border. It is believed to be wood covered by volcanic activity between 11-15 million years ago. The volcanic event covered this area in debris that deprived the plants of oxygen, halting the decay process. Minerals from the volcanic ash then acted as the replacement material for this petrification/mineralization, giving the wood these vibrant colors.
