TRUMBULL, State Geologist, Cheyenne, Wyo. INTRODUCTION This pamphlet upon the South Pass-Atlantic CityMiners' Delight district has been written in response to many inquiries, received from all parts of the country, for definite information regarding mining conditions and geology of the district. Late in the fall of 1913, the writer spent ten days in the camps. The accompanying map shows the surface geology as closely as could be determined by so short a study. Outcrops were tied to nearest land or claim corners by means of pacing and compass. The base map has been worked up from U. S. land surveys, the patented properties as shown on the maps of the Surveyor General's office, and various private surveys to the records of which access could be had. For this base map, this office is under obligation to Mr. P. F. E. Gebhard, Chief Engineer of the Timba Bah Mining Company. No effort has been made to map all the mining claims of the district. All patented lode claims are shown and a few of the unpatented which had been carefully located by instrumental survey. Nor are the patented placer lands shown; for practically all the lands along creek bottoms are patented, and the map would become too complicated were all these claims shown. Many minor details of the surface geology are certain to be found in error, but, as there is no other geologic map of the district in existence, it is thought best to publish this at this time, rather than to wait until a more detailed survey of the area can be made. This district, during the days of the rich placer deposits and the free surface ores, was a large producer, and it is believed that now, since the problem of economic treatment of the base ores has been solved, and the introduction of relatively cheap gas engine, or even electric, power has |
