The Northern Pacific Railroad corridor serves as the primary artery through this Montana landscape, tracing the southern bank of the Yellowstone River during a period of early territorial development. Surveyed in 1889 by A.H. Thompson and Frank Tweedy, the map documents the critical transit points that enabled settlement, most notably Big Timber at the confluence of the Boulder River. The inclusion of the Harrison Ferry illustrates the era's reliance on river crossings before permanent bridges dominated the valley.
