I spent a lot of years hunting and trapping in Dolly Sods.It is beautiful and lots of opportunities for pictures.Plan on carrying enough food for the entire trip.If you plan on shooting small game to eat,you are going to lose a lot of weight.
Red Creek has stock trout but there is vehicle access so it isn't real remote.There are a couple really neat streams on top but they have no trout but there are a few chubs.Leave your pole at the car.
Basically,the only small game are snowshoe hares and red squirrels.I would see snowshoe hare tracks in winter but never a sighting of the hares except occasionally in summer when there was no season.The red squirrels are around but fairly wild.
Deer can be hard to hunt on a good year as thet mostly have random patterns and don't stick to trails much over most of that country.When deer numbers are down,it can be much tougher.On one 8 day hunt I did,the wind blew violently for 6 of those days.It is the only place I have ever hunted where deer didn't seem to mind the wind.
There are a few ruffed grouse but you may go days withoout seeing one and they usually fly out way ahead.I did shoot one with my bow from a treestand,only because he stepped behind a tree and I could draw,unseen.
It can snow from Sept through May so be prepared for cold temps.
Dolly Sods is unique and beautiful country though sometimes inhospitable.I love that country.Go well prepared but don't plan on getting your meals there.
