The ENDING
In all the Westerns i've seen in 55 years or so,this is one of the greatest climaxes that i have experienced.
...because with the combination of Herrmann's music(one of the gr.scores ever for a Western !)and the Cinematography,we have a poignant,moving and heroic conclusion ever literally going off in the Sunset !

ps Add,also,Coop's dialogue at the end when he finally addresses Hayward : someone(kismet)sees that it gets done(paraphrase)...
