1951 Map of Menan Buttes

About this map

Menan Buttes dominate the southwestern quadrant of this landscape, rising as prominent volcanic features above the alluvial plains of the Snake River and Henrys Fork. This 1951 survey, with 1970s revisions, documents a complex network of water management where the St Anthony Canal and Independent Canal snake across the eastern flats. The map records the early transportation history of the region, noting the Historic Monument Site of First Ferry near the North Fork Bridge, marking where travelers once crossed these volatile waters before permanent spans were established.
