may i have a rock treat?
Sorry for the delay! Here is your rock treat!
This is opalized wood from Virgin Valley, Nevada! It is a type of petrified wood in which the plant cells have been replaced with butterscotch colored opal.
Opalized wood from this locale is fluorescent because it contains uranium! This specimen is detectably radioactive. So even though it looks like butterscotch, please don't eat it!
