Title: Geologic and structure map of the Choteau 1X2 degree 

 quadrangle, western Montana. 



Series: MBMG Montana Atlas MA 3 -A. 



Date: 1982 



The scale (1:250,000) limits the usefulness of this map to regional 

 overview. Map shows the Freezeout (?) basin underlain throughout 

 by glaciolacustrine deposits (of glacial Lake Great Falls?). The 

 glaciolacustrine sediments on the sheet are described as up to 30 

 meters in thickness. Uplands to the north are shown as underlain 

 by glacial materials overlying undivided Marias River Shale (Upper 

 Cretaceous). Uplands to the west and south are shown as Marias 

 River, Virgelle/Telegraph Creek and Two Medicine, all undivided, 

 all upper Cretaceous and with the exception of the Virgelle all 

 essentially non-aquifers.

Title: Physical, chemical and biological data for detailed study 

 of the Sun River Irrigation Project, Freezout Lake Wildlife 

 Management Area, and Benton Lake National Wildlife Refuge, 

 west-central Montana, 1990-92, with selected data for 1987- 

 89. 



Series: U.S. Geological Survey Open-file report 94-120 



Date: 1994 



This document contains descriptions of the data collection programs 

 initiated in and around Freezout and Benton Lakes in 1990, and 

 tabulations of soil, surface water and ground water, lake sediment 

 and bioassay data. Interpretation of these data is pending. 



The data assembled include numerous drill-hole descriptions, 

 ground-water level measurements and water quality analyses from the 

 Greenfields Irrigation District south and east of Freezout, 

 comprehensive water quality analyses from all Freezout Lake ponds, 

 and bottom sediment analyses from two sites in the main lake and 

 from Pond #1, and numerous soil analyses from irrigated and 

 unirrigated areas south and east of the lake.
