13.7" Petrified Wood Cast Slab - Tom Minor Basin

This is a 13.7" wide slab of a petrified wood cast from the Tom Miner Basin area of Montana. While not technically petrified wood, it's created when the the organic material is destroyed and the void is filled in with silica (agate) and other minerals. The slab has been polished on both sides, and comes out of an old collection.

This piece is exceptionally beautiful when backlit as it's partially transparent and many layers/formation left from multiple deposition events can be seen
