What is the author's style in A River Runs Through It by Norman Maclean?

The language of these stories is simple English. The language is easy to understand and appropriate for readers of all ages. The stories include some words that the reader might not be familiar with, especially the second story in which the writer introduces several terms associated with lumberjacking. However, each of these foreign terms is explained within the narration, often incorporated into the narration in such a way that the reader is not distracted by the explanation.
