.. Depending where you are in ohio is to how you go about looking for the gold. i live in stark county so i am on the end of the Glacier till zone ... lots and lots of sand and debree(sp) to move ( not unlike other gold prospecting projects ) it just seems to be more spread out here in my area .. not very concentrated.
Second .. what are you going to be using ?? just a shovel and buckets .. a sluice .. a high banker .. a dredge??
Last .. How much are you Wanting to find? in ohio if you find an ounce in a year you are doing Great .. the gold here is very very fine but with some small pickers, plinkers, and nuggets on occasions.
side note.. keep in mind it is a hobby not a get rich into early retirement process here in ohio ..
Good luck and and if you need any help shoot me off a message.
