1970 Map of Circle Bridge

About this map

The Marias River carves a deep, winding valley through the northern Montana plains in this 1970 survey. The landscape is defined by its complex drainage network, with numerous deep channels including Sixmile Coulee, Wolfe Coulee, and Cottonwood Creek cutting through the high ground to reach the river below. Human presence is sparse but concentrated at key river crossings, most notably at the namesake Circle Bridge and further west at Moffat Bridge. This map offers significant detail for researchers of the Liberty County landscape, highlighting the lonely Erickson Cem situated on the higher flats away from the river bluffs. The presence of Gravel Pits near the river indicates the localized industrial use of the valley's alluvial deposits during this era.
