That's a very cool map! I have been to Yellowstone about 4 times but I was there mainly for landscape work at Teton as well. This time, I want to spend time on wildlife; hopefully, to see the wolves.
My understanding is that the wolves are going to be really far away. We are talking 500mm - 1000mm and so even the 600mm lens + TC20 will not be helpful. Is that the case?
There are a couple of turnouts along the stretch of road right where the Yellowstone Institute camp is at, and early in the morning that's the best spot to be at with a spotting scope to see if you can find any wolves.
Another good WL spot is the Old Gardner Road, that runs one-way from Mammoth HotSprings to the North entrance, It is a dirt road so it often closes during wet weather. Some of my best Pronghorn shots are from this road, almost always a reliable place for pronghorn. The beginning of the road is tricky to find so ask for help when you are in mammoth.
Just wanted to dedicate a few shots to you all who helped me with the info you supplied. Thanks to all of you who responded; especially, Sean, for that marvelous map!
