1936 Map of Pendroy

About this map

The Great Northern railway line terminates at Pendroy, a focal point for this Rocky Mountain front landscape surveyed in the mid-1930s. The region is defined by an extensive network of named family ranches and rural schools, including Armstrong Ranch, Sullivan Ranch, and Harmony Sch, reflecting a settled cattle and agricultural economy. Water management is central to life here, evidenced by the Bynum Canal and various irrigation channels drawing from the Marias River and its multiple forks. Along the eastern slopes, several small-scale mining operations like the Hubbard Mine and Kellogg Mine are nestled near Black Buttes. The boundary between Pondera and Teton counties bisects the map, showing how early 20th-century political lines navigated the local coulees and creek beds.
