In The Far Canyon, Kelton masterfully unveils for his reader the finality of the buffalo's demise, the beginning of a time when cattle would replace the American bison on the southern plains, and ultimately end the Plains Indian culture. The novel reveals the history of the period, not in a general grand swoop of the pen, but rather, up close and personal, so his readership can judge the impact of the period upon his characters.

The novel's first chapter introduces Comanche warrior Crow Feather, whose situation is emblematic of a common recurring theme in all of Kelton's works: change. Protagonist Jeff Layne is faced with the very same dramatic problem, the devastating threat to one's self-concept inherent in change. Layne, the hide hunter from Slaughter is weary of killing and death. He decides to return to south Texas, determined to earn his living with the newest resource on the plains: cattle. And the cultures collide.

Kelton eloquently reveals the impact of hide hunters on Plains Indian culture.

Crow Feather realizes that no matter how many whites the Comanche kill, there will always be more "coming back." Crow Feather also understands that his life and the lives of his wives and children will never be easy again. Are Layne and Crow Feather of a character that will allow them to escape a predetermined fate by reaching that far canyon, or will they simply perish under the cultural dictate of their historical time?

The question is a thematic dilemma that Kelton excels at and it is what transforms his writing into serious literature.
