Boutwell, John Mason & Lester H. Woolsey; Geology and Ore Deposits of the Park City District, Utah. United States Geological Survey, Prof. Paper 77, GPO, Washington, DC, 1912. Quarto, pp. 231, 44 plates and folded maps (including large folded map of underground workings in rear pocket), 18 text figures.

The work is complete and in the original tan cloth with black ruled borders and spine titles. The binding is tight and clean with light blemish on lower spine margin. The text is exceptionally clean and bright as are all maps and plates. A perforated Univ. Idaho stamp on title page but no other markings. In very good condition.

Boutwell and Woolsey were USGS geologists who, under the direction of S. F. Emmons, over a ten year period completed the first comprehensive survey of the Park City District which lies east of Slat Lake City in Utah. At the time the district was known as one of the major lead-silver mining districts in the world. 

A detailed areal and economic geology study was completed and this was followed by a complete study of the underground workings. These were the first comprehensive geological studies of the region since the Clarence King’s 40th Survey Exploration in 1869.

The authors provide a discussion of the geography of the district and its history and development. They provide an excellent bibliography on the district’s history. This is followed by a description of the geology, stratigraphy and structure of the central Wasatch mountains, and the geology, stratigraphy, structure and igneous rocks of the district. Much of the focus is then placed on the ore deposits, their mineralogy, occurrence of the ores, and their genesis. The work is completed with a detailed description of each mine, its ores and workings. The work remains a major historical contribution to what was once a major lead-silver mining district and is now known as a major ski area.
