Title: The New World or Cooke City mining district. Park County, 

 Montana 



Series: USGS Bulletin 811-A 



Date: 1929 



This document emphasizes the petrology, mineralogy and economic 

 geology of the New World District and adjacent areas. Geologic 

 mapping at 1:31,360 scale is anachronistic, updated by Elliott 

 (1979) . 



There is a very interesting description of native copper deposits 

 found within organic-rich intervals of the upper Fisher Creek (?) 

 alluvium near the lower Glengarry adit, across the Stillwater- 

 Fisher Creek divide from the Upper Stillwater wetland. Levering 

 hypothesized bacterial reduction of oxidation products from exposed 

 chalcopyrite nearby as the source. Levering implies that this is 

 a natural process not linked to mine drainage. Bacterial reduction 

 was supported by an inoculation experiment resulting in the removal 

 of copper from various copper sulfate solutions. 



Levering also describes extensive areas of limonitic cementation 

 of post-Pleistecene(?) sediments en Red Mountain.

Title: Bedrock geologic map of the Sawtooth Ridge quadrangle, 

 Teton and Lewis and Clark counties, Montana. 



Series: USGS Geologic Quadrangle Map GQ-381 



Date: 1965 



Wagner Basin is barely on the Sawtooth Ridge quad, and although it 

 includes the Wagner Basin sampling site, it isn't completely clear 

 whether the spring discharge point is within the area covered or 

 not. 



Wagner Basin is shown underlain by depesitional sequence of
