On another occasion, Baker, who had camped with the Shoshone near what is now Medicine Bow, Wyoming, rescued the daughter of a Shoshone chief when she was kidnapped by a Blackfeet band and returned her to her father. Baker married the young woman in October 1847. The bride presented her buckskin-clad groom with a necklace made of bear claws—an emblem of bravery.
In 1858, Baker owned and operated a ferry on the Overland Trail crossing of the Green River. In the Denver newspaper interview years later, he recalled that he charged $10 per wagon for the service. Historian Charles Leckenby related in his book, Tread of the Pioneers, that when a competitor moved in nearby, the men attempted to settle their differences by each swallowing a shot of whiskey before taking rifle shots at each other. Leckenby states that Jim Bridger intervened to put an end to this foolishness.
