All of the Black Hills is sacred. It would be tough to be aware of all the possible offenses we make when taking photos. You have to go with your own heart on this one.

Yes, but just because the area is sacred to someone, doesn't mean they automatically are offended by someone photographing it. It never hurts to learn a little about the culture of an area you are going to visit; in fact, sometimes that can be just as rewarding as the actual photography itself. I agree with John, sometimes you have to just go with your gut feeling, but always be open to others sensitivities.
