2017 Map of Nelson Coulee

About this map

The Musselshell River carves a winding path along the boundary of Petroleum and Garfield counties, defining the central axis of this landscape. The terrain is dominated by a complex network of dry washes and canyons, including its namesake Nelson Coulee, as well as Bratten Coulee and Gibbs Coulee. Human markers are sparse but significant for local history, notably the Coon Cem situated near the intersection of various township lines. To the north, the map shows the transition toward the shores of Fort Peck Lake, where the drainage of Alkali Cr meets the reservoir. Transportation follows the contours of the land via routes like Stage Rd and Dunn Ridge St, which navigate the high ground between the river and the various springs, such as School Section Spring.
