There's something else I've seen many times and have shot several elk as a result. Watch for a herd moving out of the timber into the open right before dark. If you see that, be there before light the next morning because more often than not they'll still be there.
And when the move out in the AM, once they clear the timber, who ever had the cow tag puts a CNS hit on the lead cow. This puts the whole herd in a state of confusion causing them to mill a bit providing a good opportunity for your party to fill some more tags. They won't just stand there, they will be moving, but they will present a good opportunity for the hunters who are comfortable taking moving game.
