1951 Map of Mc Leod Basin

About this map

The Boulder River carves a deep valley through the heart of this landscape, separating the high elevations of Coal Mine Ridge from the rugged peaks of the Gallatin National Forest. This 1951 survey, produced for the Missouri River Basin development program, shows a transition from the agricultural lower valley to the protected timberlands of Baker Mountain and Tepee Mountain. Evidence of early 20th-century life is scattered along the riverbanks, including the West Boulder School and the McLeod School (Aband). Recreational and administrative activity is centered around the Main Boulder Ranger Station and the Old Kaintuck Guest Ranch, while geological landmarks like the Natural Bridge and Falls highlight the unique canyon topography. The map also delineates the high divide at Contact Mountain, where local water sources like Contact Creek and Anderson Springs feed the greater river system.
