What you can find: Petrified wood logs replaced with common opal, with chalcedony infilling central shrinkage cracks. Can be up to 6" across, but most are 2 - 3" across and 12 - 18" long.
Ease of Access: Difficult. The shale is very slippery when wet, the creek has deep pools, and lots of brush/fallen trees.
Locality Type: Creekbed
Additional Information: Most of the wood seems to be eroding from the gravel layer overlying the shale.
