Hubbard Basin 8 Petrified Wood Slab – Nice blues. One of my larger pierces of Hubbard Basin Petrified Wood. This piece has nice variations and features a decent amount of blues. My favorite part is the vein like structure in some of the areas. The back of the piece has a mesh adhered to strengthen the slab. The piece measures approximately 6″ x 8″ and has a thickness of about 1/2. Weighs 1lb 8.27 ounces /688 grams.
