Excerpted from the report introduction:
This bulletin was prepared with a view of furnishing the public with information concerning the location of these deposits. It is not exhaustive in its location of the various deposits, nor is the bibliography which accompanies the bulletin exhaustive as to the sources of information concerning the deposits. The “Western Slope” is divided by natural barriers into three distinct districts; the Southwestern, the Western, and the Northwestern parts of the State. These barriers have so seriously impeded transportation facilities as to limit the areas which may be served by the various railroads.
At the time of this report, railroads were still the major transportation routes to the Western Slope. Thus, this report is organized into three chapters: Chapter I. Mineral Deposits of Northwestern Colorado, Chapter II. Mineral Deposits of Western Colorado, and Chapter III. Mineral Deposits of Southwestern Colorado. Included in the report is a table showing mineral production of the Western Slope by counties to 1917, which may be of historical significance. The two plates presented the coal fields and mineral deposits of the Western Slope.
