This is the report of (then) Captain Simpson explorations in Utah Territory during 1859. While this report was submitted in 1861 it was not published until 1876 because of the Civil War. The report covers a broad range of topics from geography, geology, zoology and history that Simpson observed as he explored a route from Camp Floyd (near Salt Lake City) to Carson City, Nevada. This route was extremely important in the country's westward expansion as his route reduced the distance from the east to San Francisco by more than 250 miles. Not surprisingly, it was quickly adopted by the overland mail, pony express and the telegraph. This complete report includes 495 pp. of text, 24 illustrations and one map entitled Map of Wagon Routes in Utah Territory which details Simpson's explorations (47.5 x 26'). Quarto, hardbound in green cloth embossed covers with gilt title on spine.
