Green Larsonite, also referred to as petrified bog wood, 
is a form of petrified wood from a location near McDermitt Oregon, 
on the Nevada/Oregon border. 
It's believed to be wood that was covered by volcanic 
activity between 11-15 million years ago. 
It helps to connect with the energies of the Earth 
by keeping the vibrations of nature near. 
Meditation with Petrified wood may take you back to connect 
with a time when your Spirit was cradled by Nature.
