They are out at my ranch so I just picked them up with the forks on my tractor. If you don't have heavy equipment rachet straps, winch and surronding trees will elevate to get in a truck or 4 wheeler
I found a creek with tons of petrified wood in it. Everything from small pieces to 5 foot long logs. I took out several small pieces as specimens, but am unable to get the logs out as they are in very rugged terrain and i have to lug em out by hand.
