1969 Map of Willow Creek Dam SW

About this map

Crow Indian Reservation Boundary and the Bighorn National Forest Boundary meet in this 1969 field-checked survey of the Montana-Wyoming border. The landscape is defined by deep drainages and high relief, most notably where the North Fork Lodge Grass Creek cuts through the high country. Resource extraction is evidenced by a Marble Quarry located in the southern reaches of the quadrangle near Salt Canyon. Significant topographical landmarks such as The Mesa and Tepee Pole Ridge dominate the southwestern quadrant, providing a clear picture of the transition from the Big Horn mountains toward the plains. The map meticulously tracks several major creek systems, including Willow Creek and Beaver Creek, alongside local named features like The Slide and Percheron Canyon, which illustrate the complex water-carved geography of the borderlands.
