Yes, there are scenes in that movie that burn into your memory. The one that always grabbed me was near the end, where Ethan joins the soldiers to attack the Comanche camp. The scene was just before the attack begins, when Ethan gives a low whistle (for the soldiers to advance). There's something chilling in Wayne's eyes in that brief bit of film.
The look on his face when he goes into the cabins and sees the remains of the older daughter (IIRC)
I thought it was a powerful movie.
