About this map

The confluence of the Bighorn River and the Yellowstone River anchors this 1960 survey, a landscape defined by the shifting alluvial grounds of Pease Bottom and Big Ox Bottom. The historical site of Ft Pease (Site) sits near the northern river bend, marking an early trading and military footprint in the region. The small settlement of Bighorn serves as a focal point along the Northern Pacific railroad, which snakes through the valley following the river’s natural grade.

Transportation and infrastructure are central themes, with the primary rail line and a highway noted as Under Construction crossing the lower portion of the sheet near Pasco. The map reveals the intricate drainage system feeding the Bighorn, including Tullock Creek and the deep cuts of Petes Coulee. Topographical details also highlight the isolation of Government Island and the rugged coulee terrain to the east, illustrating the complex hydrology that influenced settlement patterns and agriculture in Yellowstone and Treasure Counties.
