About this map

Gas City Oil Field and the North Pine Oil Field define the industrial footprint of this Dawson County landscape, where energy extraction meets an extensive network of water management. The terrain is marked by a sophisticated system of small-scale reservoirs and dams, including Upper Magpie Reservoir and the Twin Buttes Retention Dam, designed to manage the intermittent flows of Magpie Creek and Cedar Creek.

Remote roads like Oilwell Rd and Fas 335 connect these isolated sites across a landscape of natural drainage features such as Abbot Draw and Forbill Creek. The presence of numerous named earthen structures like Prairie Goat Dam and the Dead Horse Dam suggests a heavy reliance on managed water for local land use, likely supporting the livestock or resource operations found throughout these eastern Montana plains.
