The Mormon row area has several great photo ops. Not only the two Moulton barns with the Tetons as a backdrop, but other buildings, a working ranch, wandering Buffalo and antelope, and the mountains themselves.
The temple that has been captured in Tomb Raider is being renewed now so there are some construction works. Nonetheless, you can enjoy the place and imagine Angelina Jolie running around. There are many rooms and buildings there and tourist start to fill all of it around 10am so you might want to visit it before - worth it!
