RM2565   "Fir" Wood Opal

Warden, Grant Co., Washington, United States

The fossil woods of the US state of Washington have been well known since the 19th century. This specimen is a wood opal from this area and clearly shows the growth rings of the tree in question. If it is a fir tree or another member of the pine trees, it is already a subject on which we cannot pronounce ourselves.
As we can read in a brochure from the 80s (visit link): "Petrified wood is found throughout the state and is symbolic of our early forests. It represents a period of geological time when extensive volcanism buried great forests with volcanic ash and basaltic lava".


Size: 7.5 x 5 x 1.7 cm.
Found in ±1975.

Col. J. Astor, Barcelona.
