1968 Map of Captain John Rapids

About this map

The Snake River carves a deep path through the canyonlands along the Idaho and Washington border, defining the rugged geography of Nez Perce and Asotin counties. This 1968 field survey documents a river corridor shaped by navigation and early settlement, where Captain John Ferry and Grahams Landing served as vital transit points. The terrain is marked by steep ridges such as Weissenfels Ridge and Montgomery Ridge, with numerous drainages like Thiessen Canyon and Sandal Gulch feeding into the main channel. Smaller outposts like Crowers and Perkins appear on the higher ground, while the river itself features notable hazards and landmarks including Buffalo Rapids and Steamboat Island. A lone Cem near the South Fork Captain John Creek provides a tangible link for genealogists researching the families who inhabited these isolated canyon reaches before modern developments changed the landscape.
