Made another attempt to today find petrified wood in Ohio in Barnesville Belmont County area, using this article as a guide:
The Aboriginal Use of Petrified Wood In Southeastern Ohio
We drove into Barnesville on route OH 800 and followed OH 148 to the southeast toward the Powhatan Point. Making a short story long… we did not find any petrified wood ourselves. Recent rains made raised the creek levels quite abit. However, in the search area, we did visit with an older gentleman who has been collecting wood in the area for 60 years and has a wonderful collection.
So the area does produce petrified just need to visit sometime in Sept/Oct when the water levels will be low.
