For Shadow Mt. You would turn right (east) onto Anelope Flats Rd which is about a mile or so nort of Moose on RT 89, follow to stop sign and trun north, follow to Forest service access road on left, camp when you get to the quakies.
Across from Cunninham Cabin is the service road for Spread Creek. Soon after leaving Teton Park boundry in a nice shady spot to camp on the left. Good grass for the horses here and water nearby.
Up the Gros Ventre Rd, about two miles past the camp ground at Slide Lake, there is good parking on the right and nice trail on the left for Horsetail Creek. Another nice ride.
If you horseback in the Spread Creek area or Pacific Creek area, there are grizzlies in both those places. Horsetial Creek and Cow Creek, maybe blacks but no griz, but could see wolves.
I have never been in Shoal Creek though. Friend of ours used to be an outfitter in there years ago. I think his son still runs his camp in there though.
Another nice ride is up on the Sleeping Indian, but little water once you get up there.
