Title: Altitude of the top of the Claggett Shale, Glasgow 1 degree 

 X 2 degree quadrangle.

Date: 1987 



Regional map compilation at 1:250,000 scale shows the natural 

 catchment of Lake Bowdoin to be underlain by the Claggett Shale of 

 Late Cretaceous age. Some contributing areas to the south may be 

 underlain by the Late Cretaceous Judith River Formation, which 

 overlies the Clagget Shale. Lake Bowdoin is shown to overlie the 

 Bowdoin(?) structural dome southwest of it's apex.

Title: Reconnaissance investigation of water quality, bottom

 the Bowdoin National Wildlife Refuge and adjacent areas of 

 the Milk River basin, northeastern Montana, 1986-87 



Series: U.S. Geological Survey Water-Resources Investigations 

 Report 87-4243 



Date: 1987 



This initial reconnaissance investigation included ground-water 

 data from two sites south and southeast of Bowdoin, surface water 

 samples from the Dodson South Canal and from 3 sites within 

 Bowdoin, along with Lakeside and Dry Lake Units. Sediment samples 

 were collected from 4 sites in Bowdoin, including one near the DHES 

 "Lake Bowdoin North Shore" site, and from Dry Lake and Lakeside 

 Units. 



This publication includes a geologic map of the Lake Bowdoin area 

 which shows a band of alluvium, linking the Beaver Creek alluvium 

 with the Milk River alluvium, passing just south of Lake Bowdoin.
