Lewistown serves as the focal point of this 1941 survey, showing a landscape defined by its mining operations and early industrial infrastructure. The area is marked by a complex network of resource extraction, including the Divide Coal Mine and Skaggs Coal Mine to the east, while an Oil Refinery sits just south of the city center. To the northeast, the Judith Mountains rise sharply, housing inactive operations such as the New Year Mine and Western Mines, signaling a shift in the region's mineral economy.
