The East Poplar Oil Field defines much of the industrial character of this northeastern Montana landscape, where the extraction economy meets the drainage systems of the Missouri River watershed. The terrain is marked by a grid-like network of rural routes, including Fas 251, which provide access to the oil infrastructure and scattered agricultural interests in this corner of Roosevelt County. Natural water features create the primary breaks in the human-imposed grid, with the Poplar River winding through the western portion and Lake Creek cutting across the northeastern section. This survey documents the intersection of natural hydrology and modern energy production in the Brockton District, showing how the land was partitioned and utilized for resource extraction in the early 21st century.
