In August 1826, against his mother's wishes, Kit ran away from his apprenticeship. He went west with a caravan of fur trappers, tending their livestock. They made their trek over the Santa Fe Trail to Santa Fe, the capital of Santa Fe de Nuevo Mexico, reaching their destination in November 1826. Kit settled in Taos.  Carson lived with Mathew Kinkead, a trapper and explorer who had served with Carson's older brothers during the War of 1812. Carson was mentored by Kinkead in learning the skills of a trapper, while learning the necessary languages for trade. Eventually he became fluent in Spanish and several Indian languages.  Workman put an advertisement in a local newspaper back in Missouri. He wrote that he would give a one cent reward to anyone who brought the boy back to Franklin. No one claimed the reward. It was a bit of a joke, but Carson was free. The advertisement featured the first printed description of Carson: "Christopher Carson, a boy about 16 years old, small of his age, but thick set; light hair, ran away from the subscriber, living in Franklin, Howard county, Missouri, to whom he had been bound to learn the saddler's trade."  Between 1827 and 1829, Carson worked as cook, translator, and wagon driver in the southwest. He also worked at a copper mine near the Gila River in southwestern New Mexico. In later life, Carson never mentioned any women from his youth. There are only three specific women mentioned in his writing: Josefa Jaramillo, his third and last wife; a comrade's mother in Washington, DC; and Mrs. Ann White, a victim of Indian atrocities.
