Gary Green Jasper a.k.a. Larsonite – Green Petrified Bogwood from near McDermitt on the Oregon/Nevada Border - Rockhounding Oregon

Called Gary Green Jasper, Larsonite or McDermitt Green Jasper, depending on who you ask, is a petrified bogwood or swamp bog, where the wood, canes and cattails and creatures living in the bog were all petrified in a Miocene age volcanic event between 11 million and 14 million years ago, a snapshot in time of the algae, fallen trees, vegetation, swamp critters and other swampy things that were happening when this bog was covered by falling ash.

The teal to lime green color of the material is caused by a combination of iron, aluminium, potassium, sodium and calcium. 

The picture above was from a fresh slabbed piece of Gary Green Jasper. What an amazing piece of green petrified wood!
