2020 Map of Calais

About this map

The Missouri River flows along the southern edge of this landscape, marking the boundary between Roosevelt and Richland counties. This area of northeastern Montana is defined by the drainage networks of several seasonal and perennial waterways that cut through the terrain. Box Elder Cr and Lone Tree Cr run through the central and northern sections, while Lake Cr appears in the far northwest. The small settlement of Calais serves as a primary point of reference, situated north of the river and connected by BIA Rte 1. Further north, Bertino Reservoir sits at the head of Lone Tree Cr, reflecting the region's reliance on water management for agriculture and livestock. The map illustrates a sparse, rural environment with roads like Co Rd 2053 providing access across the northern plateaus.
