Title: Surficial geology and water resources of the Tobacco and 

 Stillwater River valleys, northwestern Montana

Date: 1971 



Geologic mapping at scale of approx 1:84500 shows Alkali and 

 Thirsty lakes underlain by Quaternary alluvium, but surrounded 

 closely by till of unspecified age (presumably late Wisconsin). 

 Most of catchment is probably underlain by till. Alluvium is 

 likely thin, but no well records shown. No indications of till 

 thickness or of underlying stratigraphy in Alkali Lake area. The 

 bedrock outcrops are shown as Precambrian undivided. No 

 quantitative descriptions of till source composition. 



Water quality data include two conductivity measurements of 1230 

 (June 1968) and 1300 (October 1968) microsiemens/cm, and lab 

 analysis from Thirsty Lake. Thirsty lake was several times more 

 saline, much more sodic and depleted in sulfate relative to 1993 

 Alkali Lake. 



Includes generalizations about ground-water quality in study area, 

 no close by analyses but several from adjoining townships.
