What is the author's style in Banner in the Sky by James Ramsey Ullman?

The language and meaning of the story are masked heavily in tradition and custom. Some believe the mountain is evil, and the town eventually takes up this notion. Anyone wanting to climb is dismissed as crazy. The town changes, although slowly. Tradition is also apparent in the code of the guides. This dictates that a guide is responsible for his climber. This code leads to the death of Josef Matt, and it leads Rudi to save Saxo's life up on the high mountain. There is a strong moral drive to take care of one's climber high on the mountain when things go bad. Rudi and Josef pass this extreme test, while Saxo fails when he abandons the group. There is great meaning in doing the right thing.
