Stewart Edward White 
The Riverman [PDF ebook] 

During the early 20th century, the frontier was closing as Americans settled the West, and it brought forth a sort of nostalgia for stories about the Wild West, the Plains, and the frontier. Stewart Edward White was one of the authors who helped keep the Western spirit alive with his books.
It tells the story of the men who worked the logs on the rivers, back when that was the main way to get lumber from the forests to the cities. The author writes the story as fiction but there is so much detail and knowledge that you immediately buy in to the main characters. 
Plus, there is a twist.
