The biography of the famous American explorer. James Felix Bridger was one of the greatest of the explorers, mountain men and trappers of the 1820s, 30s and 40s. He walked, rode and canoed over thousands of miles of unknown and often very dangerous country in the West especially through the Rockies. He knew Brigham Young, Kit Carson, John Fremont, George Custer and many other great names of Western history. He was among the first European Americans to see the Yellowstone geysers and the Great Salt Lake.

General Grenville Dodge (who wrote in 1905 and knew Bridger in later life) described Jim as "a very companionable man. In person he was over six feet tall, spare, straight as an arrow, agile, rawboned and of powerful frame, eyes gray, hair brown and abundant even in old age, expression mild and manners agreeable. He was hospitable and generous, and was always trusted and respected."
