Hi Dave..the locations listed have been floating around the net for many, many years, it's very old information. That's why it's listed that it may or may not be accurate. When it was first posted here, it had map and gps coords, but when I crossed referenced them with my map I had..they didn't match up so I checked other maps and got the same results so I deleted those..there was no way to find out which map the original poster used.
There is gold to be found in the creeks of McKean Co, I know a gentelman who has a cabin there and he's found gold in the creek that goes through his property, he has prospected other streams in the area and has found in them. Going out and dipping a pan in a creek won't guarantee finding gold..you have to do your homework and that is learning how to read a stream and where the gold will be laying, where it will settle out during times of high water events. You have to get down to the bedrock or hardpack layer where the gold will lay.
