If you want to see mountain goats in YNP, go to the rocks SW of Mammoth, or to the rocks on the east end of the Lamar valley. I see them there regularly. Bring a spotting scope. For wolves, just north of Mt Washburn, overlooking antelope creek, I see wolves pretty often. Watched them kill a moose calf and wound the cow too. Go after Labor Day if you can, the Asians are gone by then. If you have a spotting scope set up, people will ask what you see, tell them you don't see anything or you will have to share your scope with them.
