Riding the High Wire is the first comprehensive history of aerial mine tramways in the American West, describing their place in the evolution of mining after 1870. Robert A. Trennert shows how the mid-nineteenth century development of wire rope manufacturing made it possible for American entrepreneurs such as Andrew S. Hallidie and Charles Huson to begin erecting single-rope tramways in the 1870s and 1880s. Their inventions were followed by the more substantial double-rope systems imported from Europe. By the turn of the century, aerial tramways were common throughout western mining regions, hauling everything from gold and silver ore to coal and salt and changing the face of the industry. Aerial mine tramways proved to have a special fascination; people often rode them for a thrill, sometimes with disastrous results. They were also very temperamental, needed constant attention, and were prone to accidents. The years between 1900 and 1920 saw the operation of some of the west's most spectacular tramways, but the decline in high-country mining beginning in the 1920s--coupled with the development of more efficient means of transportation--made this technology all but obsolete by the end of the Second World War. Historians and the general reader will be equally enthralled by Trennert's fascinating story of the rise and fall of aerial mine tramways.

This publication is a primer on the subject of aerial passenger tramways. It is intended for Forest Service personnel who are newly assigned to activities that are associated with these transport systems. The text, which is general and nontechnical, contains a description of tramway types, components, and terminology used in the manufacture, installation, and operation of tramways. (RLK).
