THE MINERALS OF IDAHO 11 



IDAHO MINING DISTRICTS 



The following section has in large part been taken from Hill's 

 Mining Districts of the Western United States (James M. Hill, 

 United States Geological Survey Bulletin 507, 1912), from which the 

 Idaho portion has been reprinted without change except for additions 

 to the bibliography. Such additions have been of titles of papers 

 which have come under the present writers notice which are believed 

 to have some interest, either mineralogically or as related to the 

 metalliferous mines. By no means all of the geologic literature 

 relating to the State is mentioned. 



As previously mentioned this classification of the districts has been 

 followed in the body of this manuscript and it has not been possible 

 to revise the text to conform with recent creation of new counties, 

 since it is often difficult to determine, without tedious research and 

 •correspondence, just where a given mine or district lies with reference 

 to the changed geographic boundaries. 



For references to papers on Idaho geology not mentioned here the 

 reader is referred to John M. Nichols' bibliographies published as 

 bulletins of the United States Geological Survey, particularly to 

 Bulletins 746 and 747, which are complete for the period from 1785 

 to 1918, and to subsequent bulletins by the same author. Bulletin 

 of the United States Bureau of Mines, No. 166, A Preliminary Report 

 on the Mining Districts of Idaho, Washington, 1919, should also be 

 consulted. Many references not found in this section will be found 

 in footnotes in the body of the present work. References to pub- 

 lished descriptions, in the following tabulation of mining districts are, 

 unless otherwise stated, to publications of the United States Geological 

 Survey. The abbreviations used in stating these are as follows: 



M Monograph. 



P. P Professional Paper. 



Bull Bulletin. 



W. S. P Water Supply Paper. 



Min. Res Mineral Resources. 



Folio Folio of Geologic Atlas of the United 



States. 



Top. sheet Topographic map sheet of the topo- 

 graphic Atlas of the United States. 



The data given for the Black Hornet district may be taken and 

 explained to give a key to the meaning of the abbreviations, etc., 

 used for the other districts.
