Query: The Business of the "mountain men"

Well researched, but very different from what I was expecting. This book focuses on the business aspect of 18 men who made their living trapping. This book glosses over any of the adventure, craft and technique and goes into specifics of the business transactions between the leaders and teams of the expeditions and the financieers. Kit Carson, Jim Bridger, Manuel Lisa, and other well known names are examined in these sketches of the mountain man's struggles for the elusive profits of the trapping business. I think if you're looking for an adventure book, pass this one by, but if you are a business major looking for some historical perspectives on the trapping and exploration ventures of the early and mid 1800s, then you might like this sometimes dry but factual account of the Mountain Men.
