Along the side of the road were lots of small pieces of petrified wood and one of my son's picked up a piece to show me and he wanted it....I being a law abiding woman told him..."don't you let me catch you picking up any of those pieces" then turned my back on them and walked away...even hubby (sneaky as he was called) opened up the Velvetta at the campsite and found a beautiful piece the size of the palm of my hand that magically found its way into the velvetta box...
When you leave the forest there is a ranger station with a sign reminding you its against the law to remove any petrified wood...one son had a panic look on his face and cried MOOOOOOM....I told him to shut up, the ranger asked if we had picked up any wood and to my knowledge we hadn't so I said NOPE. 5 kids and a husband said nothing.. :O)
If you had looked closely as you exited the park, the drainage ditches along side the road were MADE of ‘petrified tree’ rocks!
