Wislizenus in A Journey to the Rocky Mountains in the Year 1839rn rn With a keen and ardent eye, Wislizenus, a German physician, recounts his ramblings in the American West. Seized by a wanderlust that compelled him to leave his rural practice as a country doctor behind, albeit temporarily, Wislizenus joined an expedition of fur traders and, funded by his own modest savings, journeyed through Wyoming and Idaho on the Oregon Trail and then into Colorado. Here he regales us with notes on the geography and history of the region, as well as observations on the wildlife, plants, and peoples of the mountains, capturing in captivating words a now greatly changed realm.rn rn AUTHOR BIO:rn Frederick Adolph Wislizenus (1810-1889) was born in Germany, the son of a pastor, and originally planned to enter the ministry until the natural sciences captured his interest.
